1. Answer D. Dermoid tumor. 2. Discussion Intracranial dermoid tumors are uncommon and have been reported to comprise 0.04% to 0.25% of all intracranial masses.1,2 The most common location of dermoid tumors is the midline, in contrast to epidermoids. The posterior fossa, parasellar and frontobasal regions are common locations for dermoid tumors.3 Dermoid tumor rupture is rare, and although rupture usually occurs spontaneously, rupture following closed head trauma has rarely been reported.1–3 The presenting symptoms of a ruptured dermoid tumor include headache, visual disturbance (as a result of compression of

A typical MRI finding for a ruptured intracranial dermoid tumor are fat signals in the subarachnoid space which show hyperintensity in T1-weighted images and hypointensity in T2-weighted images.2,3 References 1.
