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...

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...

We describe a case of anaplastic meningioma presenting in an extracranial osseous location, initially diagnosed as cancer of unknown primary. Although anaplastic meningioma comprise 3% of all meningiomas, this subtype is more likely to be associated with metastases. The increased degree of dedifferentiation in anaplastic meningioma makes diagnosis difficult, especially if characteristic imaging...

background: meningioma is among the most common slow growing central nervous neoplasms, which recurs locally despite the benign histologic features. the aim of this study was to evaluate osteopontin and ki67 expressions in different histologic grades of meningioma in a group of iranian people. methods: in this cross-sectional study, first, the paraffin blocks with the definite pathological diag...

We report a case of papillary adenocarcinoma of the sigmoid colon with psammoma bodies and intracytoplasmic hyaline globules. The patient was a 59-year-old woman. The tumor showed central ulceration with smooth elevated ridges. Histologically, the tumor was composed of numerous large irregular tubular structures accompanying infolded papillary growth. The tumor cells showed cytoplasmic basophil...

Current staging methods are inadequate for predicting the overall survival of meningioma. DNA microarray technologies improve the understanding of tumour progression. We analysed genome wide expression profiles of 119 meningioma samples from two previous published DNA microarray studies. The Cox proportional hazards regression models were applied to identify overall survival related gene signat...

A 68-year-old man underwent a resection of the right middle lobe for a solitary lesion detected at computed tomography. The histologic result was suggestive for a pulmonary meningioma. Although the result of a preoperative brain computed tomography scan was negative, magnetic resonance imaging showed a skull-base meningioma. On the basis of the absence of symptoms, we decided to observe the int...

Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The pa...
