Tetraventricular Hydrocephalus And Subarachnoid Fat Vesicles Induced By Ruptured Spinal Dermoid Cyst
ABSTRACT The authors report a case of spinal dermoid cyst which ruptured; this originated a migration of free fat vesicles into the ventricles and subarachnoidal spaces. The fat vesicles caused obstructive hydrocephalus; witch represents a quite exceptional complication. The intracranial fat causing hydrocephalus was found before the discovery of the spinal mass. The authors suggest that the finding of intracranial fat in the absence of a local source makes the search for an intraspinal dermoid cyst.
