An incidentally detected third ventricle chordoid glioma.
(49/146)
Chordoid glioma is a rare low-grade tumor located in the third ventricle-hypothalamic region. Since its first report, 37 cases have been described in the literature. We report on an additional case that we considered significant because of its incidental detection and its uneventful surgical removal. (+info)

We report a case of 50-year-old man who was presented with recurrent episodes of left sided hemiparesis. CT scan and MRI brain revealed a large intraventricular fatty lesion. Histopathological examination showed a picture of angiolipoma. (+info)

Anterior third ventricle meningiomas. Report of two cases.
(53/146)
Third ventricle meningiomas are rare, representing approximately 0.15% of all meningiomas. The majority of third ventricular meningiomas are located posteriorly in the pineal region. Less commonly, they arise in the anterior part of the third ventricle. We report the cases of two patients with large and giant meningiomas originating in the anterior part of the third ventricle.

Meningiomas of the lateral ventricles. A review of 10 cases.
(54/146)
BACKGROUND: Intraventricular meningiomas are rare tumours that represent about 2% of all intracranial meningiomas, and represent one of the most challenging problems in neurosurgery. They are located deep within the brain and often are sizable and highly vascular. We report on a series of 10 meningiomas of the lateral ventricles treated at our institution during the last 28 years. PATIENTS: Ten patients (6 women, 4 men; mean age 41.6 yrs) were admitted to our medical center between 1978-2005 with meningioma of the lateral ventricles. Headache was the first symptom in 8 cases and ocular signs were present in 5 patients. RESULTS: Seven tumours were located in the right ventricle (70%) ranging in size from 2-8 cm, with 7 tumours larger than 3 cm in diameter. Nine patients underwent surgery with total excision in 8 cases and subtotal in the other; the remaining patient only received radiosurgery. CONCLUSIONS: Total resection is the gold standard for treatment which was possible in all but one of the cases undergoing surgery. (+info)
Familial occurrence of tumours of the choroid plexus.

The case histories of two children of consanguineous parents with papillomas of the choroid plexus are presented. Although exogenic factors in the genesis of these neoplasms can not be excluded, autosomal recessive inheritance is proposed. (+info)
Tumors of the lateral ventricle: the factors that affected the preference of the surgical approach in 46 patiens.
(56/146)
AIM: Optimal surgical pathway for lateral ventricle tumors is still controversial. The purpose of this study is to discuss the factors that affected the preference of the surgical techniques for removing lateral ventricle tumors. MATERIAL AND METHODS: 46 consecutive patients underwent operation for lateral ventricle tumors. The mean age was 36 years. Preoperative magnetic resonance imaging (MRI) images were examined to determine the location, expansion and size of each tumor. The transcallosal approach was used in 25 patients, and the transcortical approach was used in 21 patients. We performed MRI to determine the tumor size and recurrence or increased size of the residual tumor. RESULTS: Total resection was performed in 31 patients. Only one patient, with glioblastoma, died due to hepatic encephalopathy and intraventricular hemorrhage after the operation. Additional neurological deficits were seen 4 patients, and postoperative seizure occurred in one patient. The mean duration of follow-up was 38,37 months. CONCLUSION: Lateral ventricle tumors can be treated best by careful selection of the surgical approach according to localization of the tumor within the ventricle, the expansion side of the tumor, the size of the tumor, the origin of the vascular feeding branches, the venous drainage, and the relationship of the structures, and the histopathological features.
