Orbital malignant peripheral nerve sheath tumor: A case report and review.

Malignant peripheral nerve sheath tumor of the orbit is an exceedingly rare entity. These tumors exhibit locally aggressive behavior, recurrences, distant metastasis, and poor response to existing treatment protocols. Orbital nerve sheath tumors are often associated with neurofibromatosis 1, and malignant transformation of neurofibroma into malignant nerve sheath tumor has also been seen.

Recurrent solitary fibrous tumor of eyelid: A rare entity.

Orbital and adnexal solitary fibrous tumors (SFT) are rare entities. The clinico-radiological and histologic features overlap with those of other spindle cell variants, and hence the use of immunohistochemical stains helps in making an accurate diagnosis. Furthermore, a thorough surgical resection is imperative to prevent tumor recurrences.

Imaging Manifestations of Genitourinary Tuberculosis.

The genitourinary region is one of the most common sites of extrapulmonary tuberculosis (TB) involvement. The imaging features of genitourinary TB are protean and can mimic other entities, including malignancy, and pose a diagnostic dilemma. Hematogenous seeding and lymphatic spread of mycobacteria from pulmonary, tonsillar, and nodal TB are implicated in the pathogenesis of genitourinary TB.

Secondary Hypertension and Complications: Diagnosis and Role of Imaging.

Hypertension is a common problem; if left untreated, it can result in significant complications, including those involving the cardiovascular system and end organs. Approximately 10% of patients with hypertension are classified as having , defined as hypertension attributable to a specific and potentially remediable cause. The evaluation for secondary hypertension typically begins with acquiring the patient history and performing a physical examination and screening laboratory tests.

A Standardized Ultrasound Scoring System for Preoperative Prediction of Difficult Laparoscopic Cholecystectomy.

Purpose: Laparoscopic cholecystectomy (LC) has become the treatment of choice for cholelithiasis. Still some patients required conversion to open cholecystectomy (OC). Our aim was to develop a standardized Ultrasound based scoring system for preoperative prediction of difficult LC.

Role of Whole-Spine Screening Magnetic Resonance Imaging Using Short Tau Inversion Recovery or Fat-Suppressed T2 Fast Spin Echo Sequences for Detecting Noncontiguous Multiple-Level Spinal Tuberculosis.

Study Design: Retrospective review.

Purpose: The purpose of the present study was to evaluate the role of whole-spine screening using short tau inversion recovery (STIR) or fat-suppressed T2W fast spin echo (FSE) sequences in patients with spinal tuberculosis (TB).

Overview Of Literature: The identification of noncontiguous multiple-level spinal tuberculosis (NMLST), symptomatic or not, is important because of its management implications.

Conclusion: Proper wound care and personal hygiene are of paramount importance for good wound healing.

Neurocutaneous melanosis: Review of a rare non-familial neuroectodermal dysplasia with newer association of cerebellopontine angle cistern lipoma.

Neurocutaneous melanosis is a rare neuroectodermal dysplasia with a grave prognosis. It is actually a disorder of neuronal migration at the time of the embryogenesis hence classified as a neurocristopathy. The patients are initially identified by the skin manifestations of the disease in the form of melanocytic naevus which can be hairy or non-hairy.

Delleman Oorthuys syndrome.

Oculocerebrocutaneous or Delleman syndrome is a rare congenital syndrome characterized by microphthalmia/anophthalmia with or without orbital cysts, focal skin defects, intracranial cysts and skin appendages. We here report a case of 1-year-old male child with periocular skin tags, lid colobomas, and dermal hypoplasia. The patient had delayed developmental milestones and history of tonic-clonic seizures.

Giant-cell tumor of the patella in a skeletally immature girl.

Background: We reported on a case of a giant-cell tumor of the patella which occurred in a skeletally immature patient. This combination of unusual age of presentation and atypical location made our case clinically and radiologically unique.

Case Report: A 13-year-old girl presented with complains of knee pain and swelling.

Schwannoma of the scrotum: case report and review of the literature.

Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering the peripheral nerves. Common locations include the head, neck, mediastinum, and retroperitoneum. These tumors are usually asymptomatic until they become large and compress the surrounding tissues.

Right phrenic nerve palsy: a rare presentation of thoracic aortic aneurysm.

Phrenic nerve palsy causing hemidiaphragm paralysis is a very uncommon feature of thoracic aortic aneurysm. In one case, a 45-year-old man complained of chronic chest pain, dysphagia, and hoarseness of voice; posteroanterior view chest radiograph revealed lobular enlargement of the superior mediastinum and elevated right hemidiaphragm. Contrast-enhanced computed tomography (CT) of the thorax revealed a giant partially thrombosed aneurysm originating from the ascending aorta and extending into the aortic arch, causing a widening of the aorta-pulmonary window and a compression of the thoracic esophagus.

Clinical examination vs. MRI: evaluation of diagnostic accuracy in detecting ACL and meniscal injuries in comparison to arthroscopy.

Background: To compare the diagnostic accuracy of clinical examination and MRI in evaluation of meniscal and ACL injuries using arthroscopic findings as reference standard.

Material/methods: A total of 51 patients with traumatic knee injuries were identified and prospectively followed up with clinical examination, MRI and arthroscopy. Clinical examination and MRI findings were compared with arthroscopic findings.

Bilateral persistent hyperplastic primary vitreous: a close mimic of retinoblastoma.

Bilateral persistent hyperplastic primary vitreous (PHPV) is a rare disorder of eye. It is one of the most important differential diagnoses of retinoblastoma, hence early and accurate diagnosis is important. We here report a case of an 11-month-old child which was referred to ocular OPD with complaints of bilateral leukocoria.

Isolated pontine tuberculoma presenting as "fou rire prodromique".

The authors present the case of a young child with "fou rire prodromique" as an initial manifestation of pontine tuberculoma. This report is the first description of fou rire prodromique as the presenting sign of CNS tuberculosis. The combination of clinical information and CT findings allowed for precise localization of the lesion and suggested tuberculoma as the possible etiology.

Painless left hemorrhagic pleural effusion: an unusual presentation of leaking saccular aortic arch aneurysm.

Most thoracic aortic aneurysms are asymptomatic and are detected by chance on routine chest imaging for some other reasons. Only rarely it is symptomatic due to leak and dissection which is a potentially life threatening event that commonly presents with severe pain. In this report, we present the case of a 67-year-old man who presented with shortness of breath, intermittent cough, fever, and left sided painless hemorrhagic pleural effusion.

Giant extraosseous Ewing sarcoma of the lung in a young adolescent female--a case report.

Extraosseous Ewing sarcoma is a rare soft tissue tumour that is histologically indistinguishable from the bone Ewing sarcoma. The translocation involving chromosome 22 along with CD 99 expression is pathognomonic and is useful in differentiating from other small round cell tumours. Primary lung involvement by this malignant tumour is very uncommon and up to this date only ten cases have been reported.
