Sarcoidosis is a systemic disease characterized by granulomatous inflammation. Pulmonary
and lymphatic granulomatous involvement are common.We present a rare case report of
involvement of the central nervous system affecting the ocular region and mimicking optic
nerve sheath meningioma. We report the cas...
Pediatricmeningiomas are rare and account for only 2.2% of the central nervous system
(CNS) tumors. In this age group, they aremore frequently located in atypical sites, such
as, mainly, the ventricular system, with a frequency of 8.8 to 13.6%. Adding this to the
fact that the angiomatous subtype constit...
Anaplastic or malignant meningiomas that are classified as World Health Organization
(WHO) grade III account for less than 1% of all meningiomas diagnosed. Despite the
aggressive course, distant metastases are a rarity, occurring in only 0.1% to 0.2% of
cases. We report the case of a 56-year-old woman wh...
Resumen: Las lesiones del ángulo pontocerebeloso (APC) representan el 6 al 10% de las neoplasias intracraneales, siendo los schwannomas vestibulares y meningiomas los más comunes. Sin embargo, hasta el 15% pueden ser otras lesiones, entre ellas las derivadas a partir de restos de células melanocítica...

Introduction Meningiomas are the most common primary intracranial tumors,
accounting for up to 35% of the neoplasms in this category. Approximately 10–20%
of these neoplasms are histologically atypical, and the lymphoplasmacyte-rich meningioma
(LPM) corresponds to a very rare subtype of meningioma that...
Abstract Introduction: One of the main concerns in endoscopic endonasal approaches to the skull base has been the high incidence and morbidity associated with cerebrospinal fluid leaks. The introduction and routine use of vascularized flaps allowed a marked decrease in this complication followed by a gr...

Rosai-Dorfman disease is a benign lymphoproliferative disease with rare occurrence in
the overall population. The characteristic findings of the disease are emperipolesis on
microscopy and S-100 protein positivity on immunohistochemistry. The present report
describes the case of a 57-year-old man who pre...
ABSTRACT CONTEXT: Brain metastases are the most common tumors of the central nervous system. Because of their high frequency, they may be associated with rare situations. Among these are tumor-to-tumor metastasis and an even a rarer situation called simultaneous brain tumors, which are more related to p...
