Craniocervical neuroepithelial cyst (colloid cyst).

Neuroepithelial (colloid) cyst of the cerebellar vermis containing a xanthogranuloma.

A case of a neuroepithelial cyst of the cerebellar vermis is presented. The cyst contained a viscous fluid and a xanthogranulomatous nodule. The fluid showed high signal on T1- and low signal on T2-weighted MR images. The xanthogranuloma showed mixed intensities with partial contrast enhancement. The correlation of the cyst contents and MR signals is discussed.

FAMILIAL COLLOID CYST OF THE THIRD VENTRICLE: A CASE REPORT AND REVIEW OF THE LITERATURE

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...

Intramedullary neuroepithelial cyst of the spinal cord.

Treatment of colloid cysts of the third ventricle through neuroendoscopic Nd: YAG laser stereotaxis.

OBJECTIVE Colloid cysts (IIIVT CC) are benign neuroepithelial cysts located in the anterior third ventricle. The authors propose the use of Nd:YAG laser stereotactic neuroendoscopic for guided resection of the third ventricle colloid cysts. METHOD Eleven patients presented third ventricle colloid cysts and were treated by Nd:YAG laser guided with stereotactic endoscopy (n=7) , stereotactic en...

Calcified congenital arachnoid cyst with heterotopic neuroglia in wall.

Two unique findings, advanced calcification and ectopic neuroglia, were encountered in the wall of a giant congenital arachnoid cyst occurring in a 40 year old woman. The cyst almost totally filled the supratentorial subdural space of the left hemicranial cavity, was not connected with the subarachnoid space, and thus developed intra-arachnoidally. Its congenitally derived nature was supported ...
