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 Los meningiomas son los tumores primarios más frecuentes del sistema nervioso central, tienden a ser benignos y de lento crecimiento. Pueden ser asintomáticos o incluso manifestarse únicamente con síntomas psiquiátricos, incluyendo un cuadro psicótico. No existen estudios clínicos controla...
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...
Meningiomas are among the most common central nervous system tumors, with an
incidence that ranges from 15% to 40% of intracranial tumors. Of these, only 0.5% to 3%
are intraventricular, and the rarest of them occurs in the fourth ventricle.
Fourth-ventricle meningiomas originate generally fromthe choroi...
Chordoid meningiomas (CMs) are a rare subgroup of tumors, accounting for 0.5% of
all meningiomas. Chordoid meningioma tumors correspond to World Health Organization
(WHO) Grade II lesions and behave aggressively, with an increased likelihood of
recurrence. There are few genetic studies about CMs, but we...
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...
