Abstract

Arachnoid cysts are cerebrospinal fluid-containing brain lesions representing approximately one percent of intracranial masses. Although considered as a benign condition, in adults they may present with headache, seizures, focal neurological signs and behavioral changes due to the progressive expansion or hemorrhage. A case of a 55-year male with intracranial arachnoid cyst was reported. The patient presented to our clinic with increased partial seizures activity, almost constant right hand tremor, as well as progressive memory impairment and behavioral changes within the last six months. The neurological examination revealed mild weakness and tremor in right hand. Neuropsychological battery detected clinical symptoms of impaired memory, intellect and spatial orientation. EEG demonstrated diffuse slow-wave activity and epileptic focus in the left frontotemporal region. MRI, CT and Tc-99m MIBI SPECT scans identified neuroimaging features of an arachnoid cyst localized in the left frontotemporal region. A symptomatic add-on therapy with levetiracetam was initiated. Analyses of the current literature and of our own notices were discussed in regards to the clinical expression, management and differential diagnosis of arachnoid cysts.
