Colloid cyst of the third ventricle: sometimes more conspicuous on CT than MR.
نویسندگان
چکیده
We present two cases of surgically proved colloid cysts that were more apparent on CT scans than on MR images. These cysts, while hyperdense on CT scans, were nearly isointense with brain on multiple MR sequences. This relative lack of visibility represents a potential pitfall when imaging a patient with headache.

Familial colloid cyst of the third ventricle is very rare. This is one of the two largest families reported and the first in which all affected members are siblings. One asymptomatic sister was found by screening, emphasizing the value of screening. A brother and two sisters from a family consisting of three brothers and three sisters who were diagnosed as having colloid cyst of the third v...
متن کاملColloid cysts of the third ventricle: correlation of MR and CT findings with histology and chemical analysis.
Eight patients with colloid cysts of the third ventricle were examined with CT and MR. In six, surgical resection was performed and the material was subjected to histologic evaluation; the concentrations of trace elements were determined by particle-induced X-ray emission. Stereotaxic aspiration was performed in two. The investigation showed that colloid cysts are often iso- or hypodense relati...
متن کاملMR and CT of masses of the anterosuperior third ventricle.
Six patients with masses of the anterosuperior portion of the third ventricle were imaged with MR and CT. Four patients had proved colloid cysts, one patient had a proved astrocytoma, and one patient had a presumed colloid cyst. Multiplanar MR imaging provided accurate localization of the anterosuperior third-ventricle mass in all cases. The MR intensity characteristics of the colloid cysts var...

BACKGROUND AND PURPOSE Colloid cysts of the third ventricle are rare benign brain tumors. The purpose of this study was to correlate their patterns on MR images with the probability of success of percutaneous treatment. METHODS Nineteen patients underwent endoscopic treatment for colloid cysts of the third ventricle. The cases were divided into two groups based on difficulty of the aspiration...
متن کاملEndoscopic Treatment of Colloid Cysts of Third Ventricle: Study of Three Cases
Introduction: Colloid cyst of the third ventricle is a rare intracranial benign tumor. Traditionally, treatment is carried out by transcallosal or transcortical transventricular approach. Currently, the endoscopic treatment of these lesions is increasingly used. We reported our preliminary experience about three cases of colloid cysts treated by neuroendoscopy. Methods and Patients: We condu...
