| Abstract: | A 22 year old woman had a seizure, and the skull X-ray showed an intracranial arched calcification. CT scan permitted diagnosis of dermoid cyst. Rupture of the cyst was testified by low density areas disseminated on the cortical surface and intra-ventricular fat level. Surgical removal confirmed dermoid cyst with rupture and fat fluid inside. Authors underline infrequency of such intra-ventricular fat level. CT scan, with low density of lipidic origin promote considerably such diagnosis both of the real nature of the cyst and of its rupture. |
