35-year-old woman who died after a presumed seizure episode

A 35-year-old woman died after a witness saw her "foaming at the mouth". A seizure was presumed to have occurred by emergency personnel. At autopsy, there was mild dilatation of the lateral and third ventricles:



This translucent mass was identified in the third ventricle:


Histological examination of the cyst contents revealed:



Although no ciliated epithelium was identified within the specimen, there were columnar cells with a pseudostratified configuration:


However, the majority of the cyst lining was flattened, simple epithelium:



Diagnosis?  (Please post to comments)

Diagnosis is colloid cyst of the third ventricle. Normally one would see ciliated columnar cells lining the cyst, but they appear to be attenuated and flattened by the internal pressure of the cyst itself.

There is a larger group on Facebook called Colloid Cyst Survivors which is worldwide. My daughter was diagnosed with a colloid cyst at a young age and is being monitored with annual MRIs to track it's growth. We are in Canada and I think neuros take a wait and see approach to them here rather than operate right away. So far it has not grown at all and is 7mm. She is almost 17 yrs old. She is not symptomatic. It is my opinion that these are more common than we previously thought. Now that more people are having CT scans done for concussions etc they are showing up more often and at a younger age.
