[The presence of intraventricular fat in a case of dermoid cyst].
A 21-year-old man presented an 11-year history of generalized and temporal lobe epilepsy. In 1993 he was diagnosed by the MRI scan to have intracranial expansive lesion and underwent a subtotal removal of an epidermoid cyst. Two years later a follow-up MRI scan showed the presence of fat in the anterior horns of the lateral ventricles. In 1998 he was reinvestigated because of the increased frequency of epileptic seizures and resistance to pharmacological treatment. MRI scan showed enlargement of the cyst and presence of the same amount of intraventricular fat as in the previous examination. The radical removal of the tumor was carried out and histological examination revealed that in fact we were dealing with a dermoid cyst. During a four-year postoperative follow-up, there was no evidence of recurrence of the tumor and the amount of intraventricular fat remained unchanged. The presence of fat in CSF spaces is an indication of possible presence of specific intracranial pathology, which requires clarification. The quantity of fat may remain unchanged for many years or indefinitely.
