| ABSTRACT |
|
Intracranial teratomas are diagnosed mostly in young population and usually involve midline structure. We report a case of mature teratoma in an adult patient with unusual location in cerebellar hemisphere. A 47-year-old woman presented with severe headache and nausea. Computed tomography and magnetic resonance imaging demonstrated a posterior fossa lesion with cerebellar hemispheric location not involving midline. Histological examination of surgical specimen showed fully matured representative tissues of the three germ layers confirming teratoma. This is a rare example of mature teratoma with unusual age of the patient and location. |
