A 15-year-old female presented with primary amenorrhea and delayed onset of secondary sexual characteristics. Earlier she was operated for endoscopic third ventriculostomy (ETV) for a tense suprasellar arachnoid cyst with obstructive hydrocephalus. MRI revealed recurrence of hydrocephalus. Hormonal levels were suggestive of hypogonadism and deficiency of growth hormone. She was operated for fen...

Clear-cell meningioma is a rare subtype of meningioma which occurs at a younger age and has a higher recurrence rate than other subtypes. We report two cases of clear-cell meningioma, one in the thoracolumbar spinal canal and the other in the cerebellopontine angle. Though the CT and MR imaging findings were not different from those of ordinary meningioma, after surgical removal the condition r...

introduction: meningioma is a benign and slowly-growing tumor that is responsible for 20% of brain neoplasms. it can be accompanied by some genetic disorders such as neurofibromatosis type 2 and is more common among women. as a space occupying lesion, it produces a wide range of signs and symptoms by compressing the adjacent and underlying tissues in the brain. trauma and viruses are possible e...

OBJECT The 2-fold higher incidence of meningioma in women compared with men has long suggested a role for hormonally mediated risk factors, but specific mechanisms remain elusive. METHODS The study included data obtained in 1127 women 29-79 years of age with intracranial meningioma diagnosed among residents of Connecticut, Massachusetts, North Carolina, the San Francisco Bay Area, and 8 Texas...

Rhabdoid meningioma is a rare aggressive variant of meningioma, regarded as WHO Grade III type. Histologically and cytologically, it is distinctive type having abundant eosinophilic cytoplasm, cytoplasmic inclusion with eccentrically placed vesicular nuclei and prominent nucleoli. High recurrence rate and poor outcome are important features. Here, we are presenting a rare case of rhabdoid menin...

The study evaluated neuroophthalmologic and computerized tomography (CT) findings in 100 patients with somatotrophic adenoma and clinical picture of acromegaly, who underwent transsphenoidal adenomectomy. Prior to the surgery, visual field was normal in 77 patients. The diameter of adenoma in these patients ranged from 8 to 30 mm on CT, and the average value was 13.5 mm. Various kinds of visual...

Multiple pulmonary metastases from meningioma are rare. We report here a 59-year-old man with multiple pulmonary metastases from a recurrent intracranial meningioma. The primary intracranial tumour in the left occiput was totally excised in 2009. Pathological examination confirmed the diagnosis of atypical meningioma and adjuvant radiotherapy was given to help prevent recurrence. However, recur...

The aim of this study was to explore x-ray computed tomography (CT) and magnetic resonance imaging (MRI) characteristics specific to granular cell tumors (GCTs) of the neurohypophysis.The clinical and imaging data of 6 patients with operation-proven GCTs of the neurohypophysis were analyzed retrospectively.There were 6 patients with GCTs of the neurohypophysis confirmed pathologically. Five of ...

This case study describes a young man with symptoms suggestive of the presence of a space-occupying lesion within the cranial cavity. Imaging studies confirmed a lesion in the suprasellar region and surgical intervention to remove the tumor yielded an unexpected diagnosis. Neuroimaging characteristics and histopathology including immunohistochemistry are described. Gangliogliomas are uncommon C...
