“…The lateral ventricle is the first site of implantation of these tumors, than the third and the fourth ventricles'. Lateral ventricular tumors predominate on the left side, with more than 90% occurring in the region of the trigone [3,[6][7][8]. The principal clinical presentation of the IVM, is the raising intracranial pressure [3,4], concording with our 2 cases.…”

Submit Manuscript | http://medcraveonline.com offers to the neurosurgeons the opportunity to make precisely the diagnosis, and guide their surgical approaches. Meticulous and rational planning enable complete removal of these usually benign tumors, offering permanent cure and long term survival. This paper will discuss clinical, radiological findings, and surgical management of this pathological entity, through 2 cases of IVM managed in our neurosurgery department. First caseA 17 years old female, presented with increasing intracranial pressure syndrome, severe headache, vomiting, and papillary oedema grade1. The patient was without any sensory or motor deficit. The CT and MRI shows a huge intraventricular lesion located in the occipital Horne of the right lateral ventricle ( Figure 1). The patient underwent a ventricular shunting, and the tumor was excised in a second time. The removal was complete using a temporo parietal approach, and the post operative status was stable, with improvement of the headache. The histological exam indicates a fibroblastic meningioma (Figure 2). Second caseA 15 years old girl, consulting for severe headache, with vomiting, and diplopia. The physical examination shows no motor or sensory deficit, and right 6 th nerve pulsy, with papillary oedema grade 2. CT and MRI show a very large intraventricular tumor, located at the right lateral ventricle (Figure 3 & 4). The patient underwent ventricular shunting, and the tumor was removed in a second time. The excision was total using a temporo parietal approach, and the post operative status was simple, with improvement of the headache. The histological exam indicates a fibroblastic meningioma too. AbstractIntraventricular meningiomas IVM, make up 0,5-3% of all intracranial meningiomas, and represent one of the most challenging tumors in neurosurgery. Being initially asymptomatic usually attains a large size before detection. we review through 2 cases of IVM managed in our neurosurgery department, the clinical, radiological and evolutionary features of these lesions.

“…Meningiomas of the fourth ventricle are defined as those that have their origin in the local choroid plexus and occupy this ventricular cavity without meningeal implantation. 1,3,5 In 1963, Abraham and Chandy suggested a classification for posterior fossa meningiomas, without dural implant, consisting of three types: 1) choroid plexus meningiomas, which develop only in the fourth ventricle; 2) choroid screen meningiomas, which develop partially in the interior of the ventricle and partially in the cerebellar hemisphere and vermis; and 3) cisterna magna meningiomas, without dural implantation and with intraventricular extension, which are originate from the most lateral portion of the choroid plexus, outside the Luschka formen. 1,8,9 Those classified as types 1 or 2 are deemed true.…”

“…Among the differential diagnosis of fourth-ventricle tumors are metastasis, choroid plexus papilloma, hemangioblastoma, medulloblastoma and ependymoma. 3,5,11 The radiological differentiation of such lesions is important for the surgical planning, because it implies different levels of difficulty for total excision and, therefore, different initial forms of intraoperative management of the lesions. The characteristics of meningiomas, both in the MRI and in computeed tomograhy (CT), indicate well-circumscribed lesions with regular and mild edges, probably of slow growth, with homogeneous and very intense enhancement by the contrast agent.…”

“…1,3,4 It is believed that the meningiomas in the fourth ventricle originate from the choroid plexus, and do not present dural adhesions. 1,3,5 The first case was described by Cushing and operated by Sachs in 1938. 3,6,7 We describe the case of a 31-year-old patient, who was operated at our service for resection of a tumor in the fourth ventricle whose anatomopathological diagnosis indicated meningioma; we also performed a review of the literature.…”

Meningioma of the Fourth Ventricle: Literature Review

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 from the choroid plexus and have no dural adhesions. Most often, they manifest in young patients, around 41 years of age, with a possible predominance in females, through intracranial hypertension and cerebellar syndromes. The treatment consists of surgical resection, which commonly presents good results due to the characteristics of the tumor. So, for better preoperative planning, the radiological differentiation of the most frequent tumors in this location is important.The most common histologic subtypes are fibroblastic and meningothelial, both grade I according to the World Health Organization (WHO), although there are reports of tumors of grades II and III.We report a case of meningioma of the fourth ventricle operated in our institution, and we have conducted a literature review, through which we found that 57 cases have been reported so far, with the first one reported in 1938.

“…[ 1 ] About few such sporadic cases have been reported in the literature. [ 2 ] They arise from the choroid plexus and mostly lie strictly within the ventricular cavity. Clinical features and imaging are not characteristic to identify these lesions preoperatively, and most of them are thought to be some different tumor.…”

Meningioma's occurring intraventricular region are rare and these occurring in the fourth ventricle is even rare. Because of the rarity, it is not usually considered as a differential diagnosis in any age group. Clinical features and Imaging is not characteristic, and most of them are thought to be some different tumor. Here, we discuss two cases harboring a primary fourth ventricular meningioma Grade II, which was surgically excised successfully. Total excision was achieved in both cases and as the tumor was firm to soft and vermian splitting was not required. Understanding the clinical features and a careful preoperative radiological examination is required to differentiate this tumor from more commonly occurring lesions at this location.
