Meningiomas of the lateral ventricles

Neuroradiological and surgical considerations in 18 cases

Maurizio Fornari, Mario Savoiardo, Giulio Morello, and Carlo L. Solero

M eningiomas of the lateral ventricles are uncommon tumors. They represent about 2% of intracranial meningiomas, which, in their turn, account for 13% to 18% of all intracranial tumors. 27 Most of the reports dealing with this subject are not recent. We reviewed 18 cases of meningiomas of the lateral ventricles operated on at the Neurological Institute of Milan from 1956 through 1978 (1.5% of the 1175 intracranial meningiomas operated on in that period) with special regard to the neuroradiological diagnosis and the surgical approach.

this report we describe the case of a 52-year-old man referred for treatment of an intraventricular mass that was found to be a CG. We also discuss surgical treatment of this unusual entity, as well as possible causes of a large, aggressive granulomatous reaction within the lateral ventricle. Case Report History and Examination This 52-year-old African-American man with a history of diabetes, hypertension, hyperlipidemia, and chronic renal insufficiency presented to an outside hospital with an acute episode of transient hemi-paresis and numbness.

A rteriovenous malformations (AVM's) located entirely or predominantly in the ventricular system are uncommon. Even in the large surgical experience of Drake 3 involving 166 patients with cerebral AVM's, only six (4%) lesions were predominantly intraventricular: three in the lateral ventricle, two in the third ventricle, and one in the fourth ventricle; another five AVM's (3%) involved the basal ganglia: four were located in the thalamus, and one was in the head of the caudate nucleus. From January, 1977, through June, 1984, 70 patients with intracranial

C horoid plexus cysts of the lateral ventricle represent one of a variety of epithelium-lined cysts of the neuraxis. These cysts are a relatively common finding at autopsy. Shuangshoti and Netsky 11 noted that cysts of the telencephalic choroid plexus were observed in 66% of 124 routine postmortem specimens. These cysts are known to cause few clinical symptoms. Neither Dandy 3 nor Obrador, et al. , 9 have described a case of a cyst that produced symptoms in their very extensive reviews of lateral ventricle tumors. Since Baker and Gottlieb 2 first

170 cm in height and weighed 70 kg; her head circumference was 58.5 cm. A physical examination revealed no abnormalities and no apparent neurological deficit. Computerized tomography scans demonstrated dilation of the lateral, third, and fourth ventricles, and two separate tumors: one in the atrium of the right lateral ventricle and the other in the inferior horn of the left lateral ventricle. The two tumors were slightly hypo- to isointense on T 1 -weighted MR images ( Fig. 1 upper ) and were markedly and homogeneously enhanced by intravenous administration of

Mayfield head holder in a surgical position and registered in the neuronavigation system with an accuracy of less than 2 mm. The contralateral interhemispheric approach was performed at the lateral ventricle first, and then the ipsilateral interhemispheric approach was performed at the same lateral ventricle by passing through the same callosotomy area. Contralateral Interhemispheric Transcallosal Approach The head was positioned parallel to the floor and tilted 45° upward. 7 The scalp was incised in a curvilinear fashion and reflected toward the contralateral side.

I t is well known that both villous hypertrophy of the choroid plexus and choroid plexus papilloma cause excessive production of cerebrospinal fluid (CSF) leading to hyrocephalus. 1–4, 6, 8, However, villous hypertrophy of the choroid plexus, as identified by Davis 1 in 1924, is a rare condition. We report a case of choroid plexus hypertrophy in both lateral ventricles, which was found to be villous hypertrophy as described by Davis.

Neurosurgical Forum: Letters to the editor To The Editor Ludwig G. Kempe , M.D. Charleston, South Carolina 848 849 I congratulate Dr. Fornari, et al. , for the fine article on the sagittal paramedian parietooccipital cortical incision for meningiomas of the lateral ventricles (Fornari M, Savoiardo M, Morello G, et al: Meningiomas of the lateral ventricles. Neuroradiological and surgical considerations in 18 cases. J Neurosurg 54: 64–74, January, 1981). Some comment seems to be called for, however, when the

(Wakai S, Narita J, Hashimoto K, et al: Diverticulum of the lateral ventricle causing cerebellar ataxia. Case report. J Neurosurg 59: 895–898, November, 1983) contains a significant omission.

T umors of the lateral ventricle are rare lesions in a general neurosurgical practice; they account for < 1% of intracranial tumors. 6 Although intraventricular metastases from epithelial malignancies are extremely rare, 39 they must be considered in the differential diagnosis of an intraventricular mass. 38 Best estimates suggest that intraventricular metastases comprise ~ 6% of all intraventricular tumors, and occur in < 5% of patients with cancer. 21 Metastatic brain tumors located within the cerebral ventricles are indeed a unique challenge for
