OBJECTIVES: Three‑dimensional evaluation of maxillary sinus volume using VR mesh and correlate it with the volume of maxillary canine, lateral incisor, and dentoalveolar and skeletal dimensions in both impacted and non‑impacted sites. MATERIALS AND METHODS: In a retrospective cross‑sectional study, cone beam computed tomography scans of 100 patients with unilateral palatally impacted maxillary canine were analyzed. Canine, lateral incisor, and maxillary sinus volumes on the impaction and non‑impaction sides were measured using DICOM files, with three‑dimensional softwares (MIMICS) and VR mesh to accomplish this assessment. RESULTS: There were no significant differences in canine and lateral incisors volumes between male and female patients in the impacted side at (p > 0.05) while the maxillary sinuses volume revealed a statistical difference (P = 0.022) between male (12642 ± 810) and female (12481 ± 650) patients in the impacted side. A strong positive correlation was found between canine and lateral incisor volume for male patients in the non‑impacted (r = 0.420**, P = 0.008) and impacted sides (r = 0.334*, P = 0.038). CONCLUSIONS: There were no significant differences in the canine volume, the height of the anterior alveolar ridge (AARHMLI), and anterior dentoalveolar (ADAHMLI) of maxillary lateral incisors in the impacted/non‑impacted side, but it showed a statistically significant difference for the lateral incisors volume in the impacted and non‑impacted sides for male and female patients. The maxillary sinus volumes revealed a statistical difference between males and females in impacted and non‑impacted sides. [ABSTRACT FROM AUTHOR]

Aim and Objective : Our study was an observational and evolutional to analyze the significance of orbital volume calculation in predicting the probability or tendency of developing late enopthalmous on patients with unilateral orbital fracture with or without associated midface injury reported to our hospital. Materials and Methods: The subjects in our study included fifteen patients between18 and 60years. They were treated surgically and conservatively. Patients were exposed to series of examination from the day of injury or reporting for a consecutive period of up to six months following injury. CT was taken prior to treatment following management to evaluate the volume change in orbit. Its correlation and significance to treatment outcome were analyzed using MIMICS software by Materialise by comparing injured orbit to opposite side normal eye. Result: Conclusive of clinical examination and summary of statistical analysis patients were categorized into three groups: Low (with volume change of less than 2%), Medium (volume change between 2 to 20%) and High (volume change more than 20%) by comparing fractured orbit to uninjured orbit and a statistically significant mean value of 27.7 ± 2.6 cu.mm for fractures eye and 25.9 ± 2.6 cu.mm for normal eye was found ( P ≤≤ 0.05). Conclusion: Orbital volume can be considered as useful criteria in evaluation of patients with orbital fracture. Evaluation and follow up in correlation with resultant volume assessment provide a better indicator for assessment of prognosis and enopthalmous. Unlike other methods for volume assessment MIMICS software by Materialise provide a better method and it can be incorporated to working station in hospital. Every CT assessment in orbital trauma should include orbital volume as a parameter and this software is easy and user-friendly software that does not require its technical knowledge for application.

Proximal muscle weakness in children, as well as adults, can be the presenting feature of a wide range of diseases including but not limited to the idiopathic inflammatory myopathies, muscle dystrophies, metabolic, endocrine, and drug-induced myopathies. Certain diagnostic clues such as selective muscle involvement in inherited dystrophies, cramping on exertion in metabolic myopathies, diffuse muscular pain in endocrinal myopathies, and relevant drug history along with a lack of appropriate treatment response to steroids should be considered. Awareness of other possibilities and a keen eye to identify the mimics may avoid diagnostic delays and allow timely treatment. In this review, we cover some of the salient features of the various myositis mimics and the pertinent investigation findings as well as gray areas which may confound recognition of the underlying etiology. Later, we discuss key features of certain mimics while providing an overview of the differential diagnosis and clinical management for treating clinicians. [ABSTRACT FROM AUTHOR]

Although MRI has a spectrum of findings which help in the diagnosis of tuberculosis (TB) spine, a broad spectrum of spine pathologies resemble Pott's spine on MRI and are often missed due to inadequate clinical details. As a result, patients are often subject to unnecessary biopsy. A blinded radiologist may misdiagnose such mimic cases as TB. Our aim is to enable the reader to learn the main criteria that differentiate spine TB from other spine etiologies that mimic TB. A retrospective search was done and authors collected only MRI spine reports that showed a differential diagnosis or diagnosis of TB spine from the computer-based data records of the institution over a four-year period. This revealed 306 cases of TB spine out of which 78 cases with an alternate diagnosis that resembled TB spine were included. We describe a single institute review of 78 such cases that resemble and mimic Pott's spine on MRI. The cases being: (n = 15) pyogenic spondylitis, (n = 1) brucellar spondylodiscitis, (n = 12) rheumatoid arthritis, (n = 12) metastases, (n = 8) lymphoma, (n = 5) post-trauma fractures, (n = 10) degenerative disc disease, (n = 2) Baastrup's disease, (n = 9) osteoporotic fracture, (n = 3) spinal neuropathic arthritis, and (n = 1) case of Rosai-Dorfman disease. The clinical and radiological findings of all these cases were correlated with lab findings and histopathology wherever necessary. Appropriate recognition of these entities that resemble and mimic TB spine on MRI is important for optimal patient care. This paper exposes radiologists to a variety of spine pathologies for which biopsy is not indicated, and highlights key imaging findings of these entities to facilitate greater diagnostic accuracy in clinical practice.

Introduction: Stroke mimics are some of the common causes of misdiagnosis of stroke, with an attendant surfeit of finances and resources. Aim: We attempt to discuss some of the common neurological conditions mimicking stroke in the emergency. Methods: We reviewed the articles in English discussing stroke mimics in the last 5 years of publication. Purpose of the Review: We discuss the most common causes of stroke mimics encountered in neurological practice. In this short communication, we shall focus on the discussion of the diagnostic pitfalls and clinical clues that will help distinguish mimics from a true stroke. [ABSTRACT FROM AUTHOR]

Systemic sclerosis is a rare autoimmune connective tissue disorder characterised typically by tightening and tethering of skin. However, several other disorders are also characterised by hardening and thickening of skin. These mimics can be potentially confused with systemic sclerosis, leading to a misdiagnosis. This review describes the aetiopathogenesis, clinical features and treatment of Morphea (localised scleroderma), Scleredema, Scleromyxoedema, Eosinophilic fasciitis, Nephrogenic Systemic Fibrosis, Diabetic Cheiroarthropathy, chronic GVHD, POEMS syndrome and drug induced scleroderma like illness. A careful and thorough clinical assessment is essential in order to differentiate these mimics from each other and from systemic sclerosis, establish the diagnosis, and initiate appropriate treatment.

Multiple sclerosis (MS) is a chronic, inflammatory disease of the central nervous system characterised by immune-mediated demyelination, and is a leading cause of neurological disability worldwide. It has a wide spectrum of clinical presentations which overlap with other neurological conditions many times. Further, the radiological array of findings in MS can also be confused for multiple other conditions, leading to the need to look for the more typical findings, and interpret these in close conjunction with the clinical picture including temporal evolution. This review aims to revisit the MRI findings in MS, including recent innovations in imaging, and to help distinguish MS from its mimics. [ABSTRACT FROM AUTHOR]

Background: Despite having been declared eliminated in December 2005 from India as a public health problem, the prevalence of leprosy exceeds 1/10,000 population in certain districts/states of India. A spurt in its prevalence by 60% - from 0.74 to 1.18 within 1-year from 2012 to 2013 in the area under Pimpri Chinchwad Municipal Corporation (PCMC) of Pune district of Maharashtra, wherein our institution is located, motivated us to carry out this study. Aims and Objectives: This prospective study entailed recording of the epidemiological data of cases of leprosy and carrying out correlation of their clinical and histopathological diagnoses as per Ridley-Jopling scale along with inclusion of indeterminate and pure neuritic types. Materials and Methods: Eighty fresh untreated patients hailing from areas under PCMC-in whom leprosy was clinically considered to be either the diagnosis or the differential diagnosisreporting to the department of dermatology of our tertiary care hospital were enrolled. Their age, sex, and clinical findings were recorded on a proforma. Slit skin and scrape smear were stained by the Ziehl-Neelsen method. Punch biopsies-processed and stained by hematoxylin and eosin and Fite-Faraco method for morphological assessment and identification of the lepra bacilli, respectively-were evaluated histopathologically and a clinico-histopathological correlation, attempted. Results: Male tofemale ratio of the study patients was 2.3:1; their age ranged from 14 to 74 (mean, 36.67) years. The overall clinicohistopathological concordance observed was 70%. Five cases of indeterminate leprosy (IL) emerged on histopathological examination from among the nine skin biopsies on patients of dermatoses mimicking leprosy (pityriasis alba, postinflammatory hypopigmentation, nevus depigmentosus, etc.). Conclusion: This study enabled us to detect additional cases of IL (from among dermatoses mimicking leprosy) and led to more accurate typing, thereby underscoring the importance of clinico-histopathological correlation as an important diagnostic aid.

Leiomyomas are benign smooth muscle tumors that can arise from any organ, but are infrequently seen in the genitourinary tract. We present a case of a 55-year-old gentleman with a history of swelling in left testis since 6 months associated with pain. A clinical diagnosis of seminoma was made. On ultrasound, the same lesion was reported as mass with homogenous echogenicity with orchitis. However, histopathological examination revealed a diagnosis of tunica albuginea leiomyoma. Tunica albuginea leiomyomas are a rare entity. This case report highlights the awareness of tunica albuginea leiomyomas, which can be clinically mistaken for malignant testicular tumor.

Basal cell carcinoma (BCC) is the most common malignant tumor of skin. The most common site (80%) is head and neck. BCC exhibits a varied morphology such as adenoid, keratotic, sebaceous, basosquamous, apocrine, eccrine or fibroepithelial. Tumors with a similar histopathological picture are cutaneous adenoid cystic carcinoma and primary cutaneous cribriform apocrine carcinoma. Immunohistochemistry, along with clinical findings, acts as an adjunct in reaching an accurate diagnosis. Here, we present an interesting case of adenoid BCC in a 55-year-old man.
