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...
Objective To describe our surgical techniques, analyze their safety and their postoperative
outcomes for foramen magnum tumors (FMTs).
Methods From 1986 to 2014, 34 patients with FMTs underwent surgeries using either
the lateral suboccipital approach, standard midline suboccipital craniotomy, or the far

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 The study reviewed the histology of cases of grade I meningiomas with spontaneous necrosis, grade I without necrosis and grade II meningiomas, to evaluate the histological and immunohistochemical factors of the patients' prognosis, while correlating the clinicopathological features with the clin...
Meningiomas are common, usually benign tumors of the central nervous system that have a high rate of post-surgical recurrence or regrowth. We determined expression of the proteins merlin, NDRG2, ERBB2, and c-MYC in meningiomas using immunohistochemistry and assessed relationships between protein expressi...
