We discussed the case of a 14-year-old patient with acute onset of psychiatric symptoms for two months who had been examined and different antipsychotic drugs had been prescribed by several psychiatrists without any neuroradiological imaging. Because of unresponsiveness to the antipsychotic drugs, computed tomography and magnetic resonance imaging were performed which revealed a ruptured intracranial dermoid cyst. The patient underwent surgery and antipsychotic medications were withdrawn in short time. The emphasis of this case is that intracranial lesions can present with neuropsychiatric symptoms and findings only without any neurological deficit or signs.

On dört yasinda yaklasik olarak 2 aydir akut baslangiçli psikiyatrik semptomlari olan, herhangi bir nöroradyolojik görüntüleme yapilmaksizin farkli kliniklerde çesitli antipsikotik ilaçlar baslanan olguyu tartistik. Antipsikotik ilaçlara yanit alinamamasi üzerine çekilen bilgisayarli tomografi ve manyetik rezonans görüntülemelerde intrakraniyal rüptüre dermoid kist tanisi konuldu. Cerrahi tedavi uygulandi ve kisa bir süre içerisinde antipsikotik ilaçlari kesildi. Olguda intrakraniyal lezyonlarin belirgin bir nörolojik defisit veya bulgu olmaksizin sadece nöropsikiyatrik semptom ve bulgularla basvurabilecekleri vurgulanmistir.
