Abstract

Intraventricular meningiomas are rare and make up between 0.5% and 3% of all
intracranial meningiomas, representing one of the most challenging tumors in neurosurgery due to
their difficult location. Being initially asymptomatic, such tumors usually attain large size before clinical
presentation and diagnostic detection. Available literature concerned with their surgical management
remains scarce. Herein, we present a case of microsurgical resection of incidental intraventricular
meningioma in a 32-year-old female patient who was admitted to the hospital due to the sudden loss
of consciousness, retrograde amnesia, and nausea following a head trauma. Routine brain magnetic
resonance imaging revealed an irregular expansive formation located in the occipital horn of the right
lateral ventricle showing heterogeneous contrast enhancement. The patient underwent right-side
temporal osteoplastic craniotomy with total tumor microsurgical resection followed by external ventricular
drainage, and recovered fully afterwards. Histopathologic analysis of tumor tissue samples
confirmed the tumor as meningioma WHO grade I. Postoperative brain computed tomography confirmed
complete tumor resection. In conclusion, intraventricular meningiomas are rather rare extraaxial
tumors and may present with various symptoms depending on their size and difficult location.
The development of most modern neuroimaging methods offers the opportunity of their precise and
accurate diagnosis, better surgical planning, and favorable outcome. Microsurgical gross resection utilizing
intraoperative neuromonitoring and cutting-edge neurosurgical armamentarium remains the
treatment of choice for these location-challenging and surgically demanding, predominantly benign
intracranial tumors.
