Epidermoid cyst are benign lesions representing 0,3-1,5% of intracranial tumors. They originate from inclusions of epithelials cells during closure of neural tube. Symptoms result from compression of adjacent structures or rarely due to rupture causing Chemical meningitis. In this report, we present the case of a 34 years old male with history of ictal headache and meningeal signs. Brain CT showed hypodense suprasellar lesion with signs of rupture into the ventricular system. MRI showed a hypointense lesion on T1 and hyperintense on T2, suspecting epidermoid tumor. The Patient was operated and the sample demonstrated an epidermoid cyst. Spontaneous cyst rupture and spillage of the content into subarachnoid space or ventricles manifest as meningeal syndrome and cause high morbidity. Cyst rupture into de ventricle is infrequently described in literature.
