They usually show symptoms in the early years. Incidence of showing symptoms decrease with increasing age, some giant arachnoid cysts even become completely asymptomatic and they are detected incidentally during autopsies. Herein we reported a case who applied to the emergency department with complaint of headache and diagnosed as arachnoid cyst located on right temporal lobe and operated on thereafter. A 17-year-old male patient suffered from headache occasionally was applied to our emergency department as his headache aggravated. A cystic lesion occupying almost half of the right hemisphere and impressing on lateral ventricle was detected on computed cranial tomography of the patient whose neurological examination was found normal. The lesion was found to be consistent with arachnoid cyst on diffusion magnetic resonance ımaging carried out for differential diagnosis. Arachnoid cysts can lead to non-specific symptoms as well as they can be asymptomatic. Indications and methods of surgical treatment for these cysts are currently controversial CR - Rengachary SS, Kennedy JD. In: Intracranial Arachnoid and Epen- dymal Cysts.
