Abstract: Following anterior temporal lobectomy performed to control intractable complex partial seizures (CPS), it is rare to find a symptomatic cyst at the lobectomy site causing increased intracranial pressure and neurological deterioration. We report a 24-year-old lady who underwent anterior temporal lobectomy with extended amygdalohippocampectomy for CPS of temporal lobe origin. Ten months following the procedure, she developed a large expanding cyst at the temporal lobectomy site manifesting with recurrence of CPS, progressive focal neurological deficit and increased intracranial pressure. The patient underwent a repeat craniotomy, decompression of the cyst along with wide excision of the wall and fenestration of the arachnoid membrane into the basal cisterns. Following the procedure, the features of increased intracranial pressure and focal neurological deficit promptly improved and her seizures became better controlled. Craniotomy and fenestration of a symptomatic iatrogenic cyst following temporal lobectomy results in clinical improvement, obviating the need for a permanent cystoperitoneal shunt.
