title: [A case of neurogenic bladder due to arachnoid cyst of the middle cranial fossa].
abstract: A 6-year-old girl, with urinary incontinence for the past 3 years, showed an overactive bladder and detrusor-sphincter dyssynergia (DSD) in urodynamic study. An epileptic focus in the right occipital area, as well as a large arachnoid cyst in the left middle cranial fossa was revealed by EEG and intracranial CT. After surgery for the arachnoid cyst, urinary incontinence was improved with disappearance of the epileptic focus in EEG, and an alteration of overactive bladder into normolactive one and improvement of DSD were observed in urodynamic study. It was considered that the urinary incontinence of this case might be associated with the ectopic epileptic focus due to the arachnoid cyst.
