Adnexal torsion is a common gynecological emergency and a significant cause of acute pelvic pain in women. Hydrosalpinx-induced torsion of the adnexa is a rare situation and requires prompt and accurate management. Twenty-three years old nulliparous woman admitted in our structure for acute pelvic pain. The ultrasound revealed an enlarged right ovary with an adnexal cystic mass. We suspected the diagnosis of a right adnexal torsion due to cystic ovarian mass. Laparotomy revealed torsion of the right adnexa and a second large mass appearing to be a hydrosalpinx. Diagnosis of adnexal torsion is difficult and is based on a range of arguments obtained by anamnesis, clinical examination, ultrasonography and other investigations. Early diagnosis is important for preserving tubal and ovarian function, given the risk of ovarian necrosis in young women. Laparoscopy is the gold standard for diagnosing and treating adnexal torsion. The treatment can be conservative or radical, consisting of detorsion of the twisted adnexa, with or without adnexectomy.

Our purpose is to illustrate the radiological aspects of the annular pancreas as an etiology of duodenal obstruction in infants. We report the case of a 4-month-old girl, who was admitted to our department with postprandial vomiting evolving since birth. The initial examination found a severely dehydrated patient. Abdominal ultrasound showed gross dilatation of the stomach and duodenum, it also showed pancreatic tissue surrounding the duodenum, suggesting a diagnosis of annular pancreas as the cause of the duodenal obstruction. Post-contrast abdominal CT showed the gastric and duodenal dilatation, and a ring of pancreatic tissue surrounding uncompletly the second portion of the duodenum. The patient underwent a bypass surgery which consisted in a duodeno-duodenostomy with simple post-operative follow-up and no recurrence of digestive symptoms. Annular pancreas is a rare pathology to be sought in neonatal obstruction. A good knowledge of radiological semiology is essential for a good diagnostic approach. However, surgery is the only effective way to diagnose and treat this pathology.

A brown tumor is a non-neoplastic lesion resulting from an abnormality of bone metabolism in the context of hyperparathyroidism.We report the case of a 51-year-old woman who initially consulted for edentulism and a growing mandibular mass. She benefited from a radiological and biological assessment which made the diagnosis of primary hyperparathyroidism combined with a parathyroid adenoma.We remind through this observation the difficulty to establish a correct diagnosis in patients with an osteolytic process of the maxilla and the necessity to look for hyperparathyroidism in front of a giant cell lesion given the insidious character of this endocrinopathy.

Intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) is the first effective approved treatment for reducing ischemic stroke disability, and having a stroke within 3 months is usually a contraindication to thrombolysis. In this paper, we describe the case of a 58-year-old patient who received repeated intravenous thrombolysis at 10 days interval for a recurrent ischemic stroke, with dramatic improvement. The carotid diaphragm was behind this recurrent stroke and it was treated by stenting.

Malignant rhabdoid tumor is an uncommon pediatric tumor that often arises from the kidneys but can also develop in other soft tissues including the orbits, where it is known as atypical teratoid rhabdoid tumor. Orbital location is exceptional, with just a few reported cases. Imaging allows for an accurate diagnosis, but histological confirmation is required. The treatment is yet unclear but nearly often surgical, either with or without chemotherapy. In this report, we present a case of a neonate of 1-month-old with an orbital primary malignant rhabdoid tumor with synchronous cerebellar location. The patient was unable to undergo surgery, he had chemotherapy, and unfortunately died 1 week after following palliative treatment. We will illustrate this clinical experience and point out the importance of radiological imaging in the assessment of this uncommon condition.

Accessory breast tissue (supernumerary breast tissue) is due to the absence of regression of the primitive milk lines during embryonic life which extends from the axilla to the groin. It is mostly located in the axilla where it is often confused with the axillary extension of the breast, or any pathological process occurring in armpits. Ectopic mammary glands should not be misdiagnosed as it can potentially undergo the same pathological processes that occur in a normally located breast including benign or malignant breast tumors. We report the case of an intracystic papilloma arising from left axillary accessory breast tissue in a 63-year-old woman. The principal symptom was pain in a palpable left axillary mass without inflammatory signs. Subsequent imaging and histopathologic examination proved it to be a papillary tumor in ectopic breast tissue.

Post-traumatic testicular torsion is a rare condition, accounting for approximately 4%-8% of all reported cases of testicular torsion in the literature. Prompt clinical suspicion and intervention are crucial; as testicular torsion is considered a medical and surgical emergency that may lead to testicular necrosis. Ultrasound imaging plays an important role in assessing the integrity of the traumatized scrotum and facilitating early detection of associated testicular torsion. In this case report, we present a neglected post-traumatic testicular torsion in a 13-year-old child that led to orchiectomy.

Endometrial stromal sarcoma (ESS) is an uncommon uterine mesenchymal neoplasm. The primary extra-uterine location of ESS is a very rare occurrence.We present a case of a 39-year-old woman presented with severe abdominal pain, MRI showed bilateral ovarian tumors with heterogeneous intensity on T2-weighted imaging (T2WI) and T1-weighted imaging (T1WI), with restricted diffusion, including hyperintense areas on T1WI, not erased on T1-weighted fat-suppressed imaging, hypointense on T2WI, and not enhanced after contrast. This mass extended to the Douglas and invaded the uterine and the rectum serosa suggesting an underlying endometriosis. No abnormalities were suspected in the endometrium.The exploration revealed a friable mass arising from ovaries associated with nodules in the small intestine and sigmoid. The patient underwent bilateral adnexectomy and the anatomopathological study revealed a low-grade endometrial stromal sarcoma.This is one of the few reports covering the radiological features of low-grade extra-uterine ESS in the ovary which is probably secondary to degeneration of endometriosis with no evidence of primary uterine ESS.

Mycotic aneurysms (MA) are a rare but severe complication of systemic infections, carrying a high risk of rupture, hemorrhage, sepsis, and potential multiple organ failure. Intracranial arteries are often affected and present a significant mortality risk due to cerebral bleeding and ischemic strokes. In this paper we describe the case of a 23-year-old female patient who presented with a sudden onset of right hemiparesis, followed by loss of consciousness. Cerebral imaging revealed multiple infarcts in both hemispheres and intracranial hemorrhage secondary to ruptured pseudoaneurysms. On transthoracic echocardiogram, she was found to have a left ventricular cardiac cyst with mobile vegetations potentially responsible for mycotic aneurysms and cerebral strokes. The patient underwent endovascular embolization for the mycotic aneurysms and cardiac surgery for the left ventricular cyst with satisfying clinical outcomes. Postsurgical analysis revealed the cyst to be of hydatid (Echinococcus) origin.

Epigastric abdominal pain is a common indication for consultation. In the majority of cases, medical history, clinical examination and routine biological exams allow for an easy diagnosis. Sometimes the symptomatology is unusual, in which case it is essential to perform a complete clinical examination and to use various imaging techniques to search for eventual atypical causes. Membranous obstruction of inferior vena cava is a rare cause of such a phenomenon. We describe a Budd-Chiari syndrome caused by membranous obstruction of inferior vena cava in a 66-year-old woman with no medical history as a rare cause of epigastric abdominal pain. We will describe this clinical experience in the light of the literature and point out the contribution of radiological imaging in the diagnosis of this rare pathology.

Xanthogranulomatous pyelonephritis is a rare and aggressive form of chronic pyelonephritis, it can occur at all age groups but is more common in women than in men, supposedly relating to the increased incidence of urinary tract infections and chronic nephrolithiasis in woman. Computed tomography (CT) findings are very helpful in making the correct diagnosis, but the definitive diagnosis is still based on histology, as there are many differential diagnoses such as renal cell carcinoma and renal tuberculosis. The complications of this type of pyelonephritis are due to the involvement of adjacent organs. The most frequent ones are Psoas abscess, perinephric abscess, and sepsis. Nephrocutaneous and renocolic fistulas are less common. We report a case of a 61-year-old male, who presented to emergency for left-sided lumbar pain for whom radiological investigations confirmed a renocolic fistula complicating xanthogranulomatous pyelonephritis. The diagnosis of XGP was proven by histopathological examination of the nephrectomy specimen slides, but there was also association with an underlying malignant squamous differentiation consistent with urothelial carcinoma, which was not evident on CT. XGP is a rare variant of chronic pyelonephritis with known imaging features. The treatment of choice is nephrectomy and histopathological examination is required for final diagnosis, as there may be associated renal malignancy.

Although it was first described over 100 years ago, lumbar puncture is still an important diagnostic tool for a variety of infectious and noninfectious neurologic conditions. With the widespread use of this common and relatively safe performed medical procedure, minor and major complications can occur even when standard infection control measures and good techniques are used, including post lumbar puncture headaches, infection, bleeding, cerebral herniation, radicular pain, and even pneumocephalus in extremely rare cases. We describe a previously unreported complication of lumbar puncture performed for the diagnosis of meningitis in a 33-year-old woman with no medical history causing pneumorrachis, tension pneumocephalus, and sacral meningocele infection leading to death. Lumbar puncture is a simple diagnostic procedure with few complications, but if the technique is incorrectly performed, or if it is accompanied by occult congenital malformations such as sacral anterior meningocele in our case, the consequences can be fatal.

Close follow-up of patients with liver cirrhosis has led to increased detection of hepatocellular carcinoma (HCC) at an early stage, especially with magnetic resonance imaging (MRI) innovations. We report the case of a 70-year-old man, with a recent history of liver cirrhosis due to chronic hepatitis C virus (HCV) complicated by hepatocellular carcinoma (HCC), and for whom trans-arterial chemoembolization (TACE) was planned, as the patient was assigned Child B7 at admission. Angiography performed during the first TACE cycle shows not only the “tumor blush” corresponding to previously detected HCC but also an additional small foci of HCC uptake seen within a large dysplastic nodule giving the appearance of “nodule-within-nodule.” Early detection of hepatocellular carcinoma improves prognosis. Hence, it is essential to be aware of all early aspects of HCC, including the nodule-within-nodule appearance on cross-sectional imaging, and also in angiography, as in this case.

Intestinal malrotation is a congenital rotational anomaly that results of abnormal rotation of the gut, said to occur in 1 in 6000 live births. Common mesentery predisposes to volvulus of the midgut and internal hernias due to the left position of the cecum and appendix. The association of this anomaly with acute left appendicitis is rarely reported in the literature. Occurrence of acute appendicitis on common mesentery is a source of diagnosis difficulties, which may lead to a surgical management delay. We report a case of a 10-year-old boy, admitted for a left-sided iliac pain whose radiological investigations confirmed a left acute appendicitis associated with complete common mesentery. The child underwent laparoscopic surgery with simple post-operative follow-up.

Acute intestinal intussusception in adults is a rare condition, most often secondary to an organic lesion (tumor or inflammation), representing 1%-5% of intestinal obstructions. Pure colic intussusception on lipoma rectal causing bowel obstruction is an exceptional situation. A 60-year-old man presented to the emergency department for acute abdominal pain with marked abdominal distention and red rectal bleeding. A contrast-enhanced abdominal CT scan was performed, which revealed a recto-sigmoid intussusception on lipoma, causing mechanical intestinal obstruction. The patient underwent a partial reduction of the intussusception with partial sigmoid resection and end colostomy. Colonic lipomas of the recto-sigmoid region represent a very rare condition and a subsequent etiology for intussusception and bowel obstruction in adults. However, it should be considered in the differential diagnosis of such situations.

Background: Giant cell tumors (GCTs) are locally aggressive but rarely malignant bone neoplasms that uncommonly involve the skull. In this report, we describe a tumor of the sphenoid sinus. Case presentation: A 51-year-old female was presented with headache, and bilateral decreased visual acuity, CT scan, and brain MRI revealed an infra-sellar enhancing tumor expanding to the sellar and supra-sellar region which proved to be a GCT. the patient had received 03 months of preoperative denosumab-based treatment and imaging follow-up showed regression in size and morphology modifications of tumor tissue. Conclusion: This is one of few reports to describe the appearance of sphenoid bone GCT, and the first report to highlight the effects of short-term denosumab treatment in GCTb in such a location.

Background: Carotid Web and focal carotid diaphragm are atypical fibromuscular dysplasia. The bilateral stroke due to this dysplasia is extremely rare. We will report a series of three young patients, admitted for a bilateral ischemic stroke caused by carotid bulb web and internal carotid diaphragm. Also, we will discuss their manifestations and treatment modalities. Case presentations: In our study, we will report a series of three North African patients, two females an one male, at the mean age of 37, admitted for an ischemic stroke caused by bilateral carotid bulb web and bilateral internal carotid diaphragm.All of our patients were young and didn't have a history of drug use. Conclusions: In our series, only end-vascular treatment was performed which was necessary to prevent any recurrence. Antiplatelet therapy was used in all cases to prevent any stroke during the follow-up.
