tumors and the usual location for intracranial germinomas is the midline structures such as the pineal and suprasellar regions (1). To the best of our knowledge, intracranial germinoma primary arising in the lateral ventricle has not yet been reported in the medical literature. We describe here a case of lateral ventricular germinoma that showed rapid progression and it mimicked choroid plexitis.

We report the CT and MR appearance of a nontraumatic hemorrhagic arachnoid cyst presenting with a third nerve paresis in a 37-year-old man. The cyst, located in the left suprasellar area, contained a fluid-blood level with stigmata of subacute hemorrhage on both CT and MR studies.

Chronic pulsatile subcutaneous administration of low doses of gonadotrophin releasing hormone (GnRH) is an effective therapy for men with hypogonadotrophic hypogonadism. Hypersensitivity reactions to GnRH are rare. We wish to report hypersensitivity reactions with intravenous GnRH after low dose subcutaneous pulsatile GnRH treatment in two men with hypogonadotrophic hypogonadism due to suprasel...

Unilateral central or centrocaecal scotoma may result from optic nerve compression. However, such defects bilaterally usually indicate non-compressive optic neuropathy of toxic or nutritional, hereditary, or demyelinating origin. Three cases are reported of patients who presented with somewhat atypical bilateral central or centrocaecal scotomata and were found to have suprasellar mass lesions d...

PURPOSE To report an unusual case of optic nerve seeding 12 years following treatment of a suprasellar germinoma. METHODS Observational case report. RESULTS A 34-year-old woman presented with a 3-week history of subjective right eye visual loss. She had been diagnosed with a suprasellar germinoma at 22 years of age, which had been partially excised and radiated (5400 cGy). The tumor had sho...

Motor activity in healthy young humans displays intrinsic fluctuations that are scale-invariant over a wide range of time scales (from minutes to hours). Human postmortem and animal lesion studies showed that the intact function of the suprachiasmatic nucleus (SCN) is required to maintain such scale-invariant patterns. We therefore hypothesized that scale invariance is degraded in patients trea...

OBJECTIVE Suprasellar meningiomas have been resected via various open cranial approaches. During the past 2 decades, the endoscopic endonasal approach has been shown to be an option in selected patients. We wished to examine the learning curve for parameters such as extent of resection, visual outcome, and complications. METHODS We retrospectively reviewed a consecutive series of patients in ...

AIM To evaluate clinical findings and magnetic resonance imaging (MRI) characteristics of Rathke's cleft cyst (RCC) in 22 patients. MATERIALS AND METHODS Twenty-two patients were imaged using non-enhanced MRI and 17 underwent an additional contrast-enhanced MRI examination. Fifteen patients received an additional non-enhanced computed tomography (CT) examination, and amongst these, two underw...
