Intracranial epidermoid cyst diagnosis

Diagnostic procedures evolved from angiography and ventriculography to non-invasive computed tomography and MRI 1).

CT

The typical imaging appearance is homogenous non-enhanced hypodense on CT. The CT density of the epidermoid cyst is usually between −2 and +10 Hounsfield units (HU) 2) 3).
