Isolated nerve sheath tumors of the uterine cervix are very rare entities. This is especially true for benign nerve sheath tumors. We present, to the best of our knowledge, the first case of a benign nerve sheath tumor resected hysteroscopically. Our patient is a 69 year-old white female with a history of post menopausal bleeding. Initial workup included an endometrial biopsy and an ultrasound....

A 38-year-old man was diagnosed with malignant peripheral nerve sheath tumour of the maxilla. He was treated with total maxillectomy. Histopathological examination of the resected specimen revealed a close resection margin. The tumour was of high grade with an MIB-1 labelling index of almost 60%. At six weeks following the surgery, he developed local tumour relapse. The patient succumbed to the...

PURPOSE To describe four patients with optic nerve sheath meningioma in whom visual improvement began to occur even before completion of a standard course of radiation therapy. DESIGN Retrospective case review. METHODS A review was conducted of 35 patients who received stereotactic three-dimensional conformal radiotherapy for optic nerve sheath meningioma from 1990 to 2005. RESULTS Four p...

A 53-year-old man presented with a 5-month history of visual loss in his left eye. Visual acuity could be corrected to 20/20 with an increased hyperopic correction. Dilated funduscopy showed faint choroidal folds and elevation of the left optic disc. The coronal view of T2-weighted magnetic resonance imaging demonstrated a fluid-filled dilated sheath surrounding normal optic nerves. General phy...

BACKGROUND AND OBJECTIVE The recommendations for the level of injection and ideal placement of the needle tip required for successful ultrasound-guided sciatic popliteal block vary among authors. A hypothesis was made that, when the local anesthetic is injected at the division of the sciatic nerve within the common connective tissue sheath, the block has a higher success rate than an injection ...

PURPOSE To describe the arterial blood supply, capillary bed, and venous drainage of the rat optic nerve head. METHODS Ocular microvascular castings from 6 Wistar rats were prepared by injection of epoxy resin through the common carotid arteries. After polymerization, tissues were digested with 6 M KOH, and the castings washed, dried, and coated for scanning electron microscopy. RESULTS Imm...

purpose: to assess the histopathological and immunohistochemical features of orbital spindle cell tumors. methods: a descriptive, retrospective study was performed on 63 pathology reports on all types of orbital spindle cell tumors at the pathology department of farabi hospital between 1995 and 2005. immunohistochemistry studies for different markers, such as smooth muscle actin, desmin, s100 p...

introduction: elevated intracranial pressure (icp) is a major and potentially lethal disorder in patients admitted to the emergency department (ed). several methods are being used to investigate for elevated icp. here we assessed and compared the diagnostic accuracy of two existing tools of ophthalmoscopy and optic nerve ultrasonography in detection of elevated icp. methods: 131 participants wi...

Malignant peripheral nerve sheath tumours are uncommon aggressive soft tissue sarcomas that originate from peripheral nerves or cells associated with the nerve sheath. Scalp malignant peripheral nerve sheath tumours are extremely rare and the role of multimodality management is unclear. We report a 43-year-old female with scalp swelling and rapid growth. Imaging demonstrated an ...
