Abstract:
We describe the unique case of a 6-year old boy who presented with recalcitrant generalized tonic-clonic seizures and clinicoradiological features of congenital Cirsoid aneurysm. The lesion was supplied by occipital arteries and a large right parietal parasagittal intracranial feeding artery in a Yokouchi type C pattern. The venous drainage was communicating with the posterior part of the superior sagittal sinus. Six months after successful ligation of the feeding arteries and complete surgical excision of the lesion, the patient remains seizure free.
