A rare case in emergency department: intracranial dermoid cyst rupture

Intracranial dermoid cysts (IDC) are rare cystic lesions that are present from birth. After rupture of these cysts, patientsmay present to the hospital with ischemic cerebral symptoms, headaches, seizures, syncope, and meningitis. Brain magnetic resonance imaging (MRI) is the most sensitive radiologic method in the diagnosis of IDC rupture, which has a high mortality rate. Patients should be rapidly evaluated for surgery if a symptomatic and ruptured cyst is detected. In this presentation, we aimed to describe the diagnosis and treatment of IDC in a 23-year-old male patient brought to the emergency department after syncope.
