This axial (cross sectional) CT image shows a multilobulated, low density mass in the fourth ventricle with a few scattered calcifications. This represents an epidermoid cyst which is a congenital lesion consisting of keratinized epithelium with desquamation. These expand/grow over time. This is the same as a congenital cholesteatoma. This resulted in obstructive hydrocephalus in this case. | |
