Abstract
- The locations of 9 ventricular tumors were outlined by radiological studies and their natures were determined by pathological studies following surgical intervention except for two cases. Clinical manifestations, radiological findings and incidence of the various tumors with regards to their locations in relation to the ventricles, were analyzed. Following are the results: 1. Of the 9 cases, 4 were lateral ventricular tumors, and the rest were third ventricular tumors. Of the lateral ventricular tumors 2 were meningiomas while the other 2 were ependymomas. Observations revealed that either meningioma or ependymoma were found in both the right and left ventricles. 2. The 5 cases of third ventricular tumors were diagnosed after neuro-radiological studies. Surgical interventions were performed on three. The type of tumors was determined by pathological studies of the surgical specimen which revealed, one colloid cyst, another meningioma and the other teratoma. 3. The predominating neurologic manifestations were headache and papilledema. The lateralizing sing occurred more frequently in those with the lateral ventricular tumors. Paroxysmal headache were experienced in the case with colloid cyst, meningioma of the third ventricle, and choroid plexux papilloma of the lateral ventricle. 4. The most prominent radiological find was ventricular dilatation. The dilatation of anterior choroidal artery was observed in one cases of meningioma of the lateral ventricle. Secondly changes of the sella turcica due to increased intracranial pressure were seen in cases of lateral ventricular tumors and in 3 cases with the third ventricular tumors. In the colloid cyst there was an elevation on the anterior portion of the internal cerebral vein while the rest of the veins were flattened and displaced downward on the lateral view. 5. The cerebrospinal fluid protein content was significantly increased in 5 cases and electoencephalogram revealed either a focal or a generalized abnormal activity in the 6 cases. 6. In these studies we found out that Conray ventriculogram has the distinct benefit in accurately outlining tumors in the ventricles as compared to pneumoventriculogram.
