Objectives: To report the experience of Ibn Rochd oncology center on management of solitary bone plasmacytoma. Describe the radiological findings in bone solitary plasmacytoma throughout plain radiographs, CT and MRI. Methods: Ten cases of solitary bone plasmacytoma were collected retrospectively in the Ibn Rushd-oncology center over a period of 8 years. Results: The mean age was 57 years old (range 48-68) and the mean consulting time about 8 months (range 4-24). The plasmacytoma was vertebral in six cases, in the pelvis in two, in a maxillary sinus in one, and in the cranial vault in one case. The most common primary clinical signs were pain and neurological disorders. The diagnosis was based on imaging data (plain radiographs, CT and MRI) and histological examination of bone biopsy. A research assessment for multiple myeloma was achieved in all cases and found normal. Radiotherapy graded 40 to 45 Gy was delivered in ten patients. Decompressive laminectomy was performed in four patients. After the end of treatment, there has been a regression of pain in eight patients and recovery of neurological disorders in half. Conclusion: Solitary bone plasmacytoma is a malignant tumor developed from plasmocyte cells. Its diagnosis is retained after a looking for a negative multiple myeloma. The basic treatment of solitary plasmacytoma bone is radiotherapy, which provides the best local control. Surgery is useful only in cases of nerve compression or bone instability.

Introduction: Lung small cell carcinoma is a neuroendocrine tumor, it is a very aggressive tumor characterized by its propensity for invasion and metastasis. The aim of our study is to describe the typical CT scan appearance of small cell lung carcinoma. Patients and Methods: This is a retrospective study of 22 patients with lung small cell carcinoma and explored by chest computed tomography (CT) with upper abdominal cuts. Our study was focused on the characteristics of the tumor process, the lymph nodes involvement (hilar and mediastinal), mediastinal structures invaded, lung parenchyma signs and parietal pleural extension. We also describe the secondary locations to abdominal floor. Results: The tumor processes were headquarters in 80.2% of cases. Their outlines were irregular in shape and lobed central in peripheral forms. The average number of mediastinal lymph node chains achieved was 2.4. Hilar or mediastinal lymph node was observed in 90%. Mediastinal structure most often invaded was the ipsilateral pulmonary artery (55.7%). Ventilation disorders, obstructive, were observed in 18% of patients presenting a central form. 54% of patients had extra-thoracic secondary locations at initial staging. Conclusion: The small lung carcinoma cells present in the majority of cases, such a proximal tumor; with mediastinal-pulmonary hilar extension. Chest CT allows determining the size of the tumor, its location and mediastinal invasion .She also clarifies the contact with the vena cava, the heart chambers, especially the pulmonary arteries.

Introduction: Brain metastases are rarely localized in the corpus callosum (CC), and exceptionally multiple within the same CC. They present clinically as a intracanial hypertension syndrome and sometimes by specific symptoms resulting from disturbance of functions in CC. Observation: We report the case of a 65-year-old patient, presenting with a continuous headache lasting from two months ago, without fever or visual disturbance or cerebri (intracranial hypertension), or seizure. They are accompanied by poor concentration and irritability lasting for 6 months. Neurological examination revealed ideomotor slowdown, a normal walk, apraxia, without motor and sensory deficit or balance disorder or coordination. The Mini Mental State (MMS) amounted to 26/30. A brain CT scan is requested showing a hypodense lesion occupying the splenium of the corpus callosum, and a hypodense lesion in the body with periphery contrast enhancement. The hemispheric disconnexion syndrome (HDS) is sought and MRI is conducted for trying to predict the nature of the lesions. Conclusion: HDS is a rare entity, as much that it occupies almost never the center stage of clinical presentation in the pathology of the corpus callosum. It comprises a series of specific symptoms. Knowing them could help anticipate the topographic diagnosis of a lesion before performing imaging. [ABSTRACT FROM AUTHOR]

Introduction: Rhabdomyosarcoma is a relatively common malignancy of the facial. It affects older children and young adults. The locations are often orbital and nasal passages. Diagnosis is based on the complementary contribution of radiology and pathological examination, sometimes only test confirmation. The aim of this work is to point out the contribution of imaging in the diagnosis of these tumors. Observation: An 18-year-old patient, consultant for a swelling of the right lateralized gradually, increasing volume palace and extending the maxilla, with intermittent bleeding and unencrypted fever. CT objectified extensive bone destruction interesting right hemi mandibular, the upper right maxillary bone lysis palace, the walls of the maxillary sinus and nasal cavities. The nasopharynx is also compressed by the tumor mass, the rétrozygomatomaxillaire Pterygomaxillary lodges and is invaded. A biopsy was performed and confirmed the diagnosis. CT brain and abdominal ultrasound were normal. Conclusion: Rhabdomyosarcoma is a common mesenchymal tumor extension is fast. The prognosis is directly related to the existence of metastasis, hence the need to know early diagnosis and establish a complete and accurate staging. [ABSTRACT FROM AUTHOR]

Introduction: Intraocular non-Hodgkin lymphoma (IONHL) runs a uniformly fatal course. Once the central nervous system is involved, survival without treatment is very limited. Although treatment does not substantially improve the long term survival, it provides short term improvement in these patients. Observation: We report a case of an intraocular non-Hodgkin lymphoma in a patient treated at the Oncology Center Ibn Rochd of Casablanca. It was about a patient of 31 years with no specific pathological history, who presented in April 2013 with clinical symptoms of redness in the right eye and decreased visual acuity. Ophthalmological tests showed a right blindness and ocular ultrasound an incomplete posterior detachment of the retina with a cataract. This assessment concludes to an anterior right sclero-uveitis. The patient received systemic corticosteroids. Given the persistence of symptoms and the appearance of sclerotic nodules, an etiologic looking for a systemic disease was found normal. Cranio-orbital scanner objectified diffuse infiltration of the intraocular soft tissues and biopsy of nodules confirmed the diagnosis of peripheric TNHL. The complementary staging found submandibular and jugular-carotid lymph nodes with laryngeal thickening. Before the diagnosis of IONHL, the patient received chemotherapy (2 cures of DHAP) and local radiotherapy (45 Gy) followed by enucleation of the right eye. The evolution was marked by the death of the patient due to brain metastases with a term of 15 months. Conclusion: IONHL presents as the form of several clinical features. Treatment was initially based on radiotherapy. Recently, combination with chemotherapy has improved survival and tolerance, especially after the introduction of intra-vitreal chemotherapy.

Introduction: Malignant transformation of mature ovarian teratoma to epidermoid carcinoma is a very rare complication, representing 1-3% of cases. It is seen most often in women of pre-menopausal or post-menopausal period and which the risk increases with age. Observation: We report the case of a 51-year-old woman, in the pre-menopausal period, who presented with abdominal pain associated with a pelvic mass. Abdominal and pelvic ultrasound showed a right ovarian tumor. Hysterectomy without annexial conservation associated with omentectomy was performed, revealing a squamous cell carcinoma in a mature teratoma of the ovary, so the patient received chemotherapy with paclitaxel and carboplatin with a good evolution after a loss of 1 year. Conclusion: Treatment of malignant mature ovarian teratoma is the same as epithelial ovarian cancer. Prognosis depends on several factors, with a survival rate of 70% in stage I and 11% in the advanced stages. [ABSTRACT FROM AUTHOR]

Introduction: The hemangioma is the most common primary tumor of the spleen. It can be isolated or register among haemangiomatosis. It is a rare tumor with a definitive diagnosis which can only be confirmed by a surgical approach and by histological examination of the surgical specimen. Observation: We report the case of a female patient of 67 years, which complained during a year before of left upper quadrant pain, of gravity type. The clinical examination revealed a huge splenomegaly arriving until the hypogastrium. Abdominal ultrasound showed a large splenomegaly measuring 25 cm in long diameter, with heterogeneous echostructure including multiple hypoechoic areas. The patient underwent splenectomy and diagnosis of cavernous hemangioma was confirmed by histological examination. Conclusion: The purpose of this observation is to highlight the difficulties in preoperative diagnosis of this lesion and determine the therapeutic approach that is required. [ABSTRACT FROM AUTHOR]

Introduction: The osteochondromatosis is a rare metaplasia of the synovial tissue characterized by the formation of cartilaginous body (chondromas) or osteochondral (osteochondroma) in a joint, bursa or tendon sheath.This condition is usually mono-articular and preferentially affects the knee. The topography of the ankle is exceptional. The purpose of this study was to report a rare case of osteochondromatosis of the ankle and the contribution of imaging in the diagnosis of this pathology. Observation: An old woman of62 years consulting for mechanical intermittent pain in the right ankle associated swelling of the anteromedial surface of the ankle for 6 months. The radiograph shows several calcifications facing the anterior side of the tibia. The CT scan of the ankle has objectified the presence of multiple bone fragments next to the - internal anterior side of the ankle with varying size, some of which are regular limits and others are calcified cartilage. These fragments seem to come off the underside of the anterior tibial pilon. It joins in a tibial-talar and subtalar arthrosis. Conclusion: The osteochondromatosis of the ankle is a very rare location that requires as any other location, early detection before installing the chondropathy. [ABSTRACT FROM AUTHOR]

Purpose: In testicular lymphoma, tumor cells grow infiltrating through the tubules and through the normal testicular vessels, and the normal vascular architecture of the testis is preserved. wether the macroscopic appearance is nodular or diffus. The aim of this study is to describe the grey-scale and Doppler findings in testicular lymphoma, and to evaluate whether identification at color Doppler ultrasound of testicular vessels with straight course crossing a mass in improving characterization of the lesion. Materials and Methods: A cohort of 21 patients with testicular mass underwent scrotal Doppler ultrasound within the period between June 2012 and May 2014. Color Doppler images were available were reexamined to assess the features of the lesion, either mass forming or diffuse, and presence of normal testicular vessels with straight course crossing the lesion. Results: Thirteen patients with pathologically-proven lymphoma were found, five patients were carrying another histological type and 3 patients in whom lymphoproliferative disease was suspected on clinical and US ground and pathology or clinical evolution showed non-neoplastic disease. Lymphoma patients age ranged 21-72 y (median: 64 y). Eight patients had primary disease and one had testicular involvement in sistemic disease. None had bilateral involvement. Patients with non neoplasic lesions (three patients) had proven non-specific inflammation (n = 1), granulomatous orchitis (n = 1) and tuberculosis (n = 1). Involvement of the testis was focal in six patients with lymphoma, diffuse in the others. Color Doppler US demonstrated normal testicular vessels with straight course within the tumor in the nine cases of lymphoma. Conclusion: In patients over 60 and/or with history of lymphoproliferative disease presenting with a testicular mass lymphoma must be considered; Demonstration of normal testicular vessels crossing the lesion is a useful adjunctive criterium to confirm the diagnosis. Inflammatory lesions may present the same imaging features as lymphoma. These criterias should be researched by the radiologist to predict eventually the kind of tumour as preoperative approach.

Objectives: Magnetic resonance (MR) imaging plays a pivotal role in assessment of prostate cancer. We review the currently available MR methodologies for the evaluation of prostate cancer in a practical and integrated clinical context, discuss and illustrate the recent advancements in the field. We also argue the advantages and limitations of current diagnostic MR imaging of the prostate. In addition, we develop an imaging algorithm for MR imaging protocol of the prostate cancer. Methods: Experience of our department and pictorial review of literature. Results: Prostate cancer is the most frequently diagnosed cancer in males. It's can be divided into detection, localization, and staging; accurate assessment is a prerequisite for optimal clinical management and therapy selection. Traditional prostate MR imaging has been based on morphologic imaging with standard T1-weighted and T2-weighted sequences, which has limited accuracy. Recent advances include additional functional and physiologic MR imaging techniques (diffusionweighted imaging, MR spectroscopy, and perfusion imaging), which allow extension of the obtainable information beyond anatomic assessment, and provides the highest accuracy in diagnosis and staging of prostate cancer. Conclusion: Owing to its exquisite soft-tissue contrast, MR imaging is well suited for assessment of the prostate. It's a rapidly evolving field, and the application of many new techniques to the evaluation of prostate cancer will continue to improve the diagnostic accuracy of prostate cancer.
