“…Still, intraventricular meningiomas (IVMs) are rare lesions with an incidence of approximately 0.5%-3% of all intracranial meningiomas [6][7][8][9][10][11][12][13] . As with other meningiomas, a female predominance was observed in previous research, while most of IVMs were diagnosed after the third decade of life, and were less common in pediatric patients 6,[14][15][16][17] . They are mostly observed in lateral ventricles, especially the left one, with trigone region being the most common location in more than 90% of cases 8,12,14,[18][19][20][21] .…”

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.

“…Only few cases require surgical intervention because of progressive intracranial hypertension and mass effect caused by dilated temporal horn. Several factors were reported to be related to the occurrence of postoperative ETH, including meningitis after surgery, neurologic deficits after operation, and inappropriate ventricular drainage[5]. In our case, a large trigon meningioma was resected.…”

“…Entrapment of the temporal horn (ETH) is characterized by dilation of the temporal horn of the lateral ventricle, caused by cerebrospinal fluid (CSF) obstruction at the trigone level. It is secondary to several pathological conditions, including infection[1], intraventricular hematoma[2], parasitic infection[3], arteriovenous malformation[4], and intraventricular tumors[5]. Most reported cases of ETH were secondary to these pathological conditions.…”

BACKGROUNDEntrapment of the temporal horn (ETH) is a rare pathologic condition. It is a kind of focal hydrocephalus caused by obstruction of flow pathway of cerebrospinal fluid. It is caused by various conditions, but ETH secondary to postoperative gamma-knife radiosurgery (GKS) is extremely rare.CASE SUMMARYA 52-year old previously healthy woman underwent resection of a large intraventricular meningioma. A small fragment of residual tumor with no obvious enlargement of the temporal horn was observed 3 mo after surgery, and she was referred for GKS. Two months after GKS, she complained of headache and progressive paralysis of the left limb. Magnetic resonance imaging revealed enlargement of the temporal horn. There was a second procedure to resect the residual tumor 8 mo after GKS. After the second procedure, she recovered smoothly. As of the date of this writing, she has remained in good condition.CONCLUSIONThis case reminds us that ETH should be considered in the treatment of intraventricular meningiomas, especially before GKS.

“…Female dominance was observed in present study which was similar to previous researches. [8,12,13] Most of intraventricular meningiomas were diagnosed after 3rd decade of life span and less common in pediatric patients which was contradictory to Germano and his colleagues’ [14] opinions that the frequency was higher in child. Ventricular meningioma appeared large in size due to the extensively available space, which posed challenges to neurosurgeon regarding to gross total tumor resection.…”

Intraventricular meningiomas are rather rare and only represent a small proportion of all intracranial meningiomas. Data are still limited toward this peculiar entity and surgical resection remains challenging for neurosurgeons. The purpose of present study is to demonstrate clinical features, surgical treatment, and potential risk factors determined long-term prognosis of intraventricular meningiomas. A total of 89 surgically treated and histopathologically confirmed intraventricular meningiomas were identified in our institution from 2008 to 2018. Clinical features, neuroimaging findings, surgical records, and prognosis data were extracted and reviewed retrospectively. Group comparison and recurrence-free survival analysis were performed. Female predominance was well established with a sex radio of 2.1:1. Raised intracranial pressure and decline of visual acuity were 2 chief symptoms that patients generally complained of. Preoperative magnetic resonance imaging (MRI) scans were performed in all patients and there was a trend toward lateral ventricular meningiomas were larger in size than others ( P = .07). Superior parietal lobule and temporal approach were widely adopted and lateral/4th ventricular meningiomas were more easily to acquire total tumor resection as compared with 3rd ventricular meningiomas ( P = .03). After an average follow-up of 57.3 months, 6 patients experienced recurrence of disease in our series. Individuals with subtotal resection ( P < .001) and higher World Health Organization classification ( P = .001) were more prone to relapse. Intraventricular meningiomas presented with a wide variety of symptoms. Surgery remained 1st treatment of choice and optimal surgical approach should be planned individually based on preoperative MRI evaluation. Patients underwent subtotal tumor resection and with malignant tumor nature should be carefully monitored during follow-up.
