Case contributed by David Cuete


Study requested for clinical suspicion of stroke

Patient Data

Age: 55 years
Gender: Male

CT brain


CT demonstrates a hypodese ovoid mass involving the left lateral  ventricle and appears to protrude anteriorly into falx , producing a slight mass effect, displacing the midline. No calcifications or cystic degeneration are observed in the mass. After the injection of intravenous contrast, no mass enhancement is observed,  but an hypodensity is evident in the body of the corpus callosum. No hydrocephalus is observed.

Case Discussion

This mass given its characteristics was reported as a subependymoma of the lateral ventricle.

Subependymomas are rare benign intraventricular, with indolent growth and usually asymptomatic. It preferably located at the lateral ventricles and the fourth ventricle. Usually result from a incidental finding in imaging studies or autopsy. Rarely become  a symptomatic lesions.

It is important to distinguish from a central neurocytoma especially if located in the third ventricle or lateral ventricle.
