SSK Okmeydanı Eğitim Hastanesi, Nöroşirürji Kliniği, İstanbul We present a case of partially thrombosed giant aneursym of the posterior inferior cerebellar artery (PICA). Giant aneursyms of the PICA are quite rare. 50- 60 percent of giant aneursyms are thrombosed, but complete obliteration of the aneurysmal sac is uncommon. Bleeding tendency of the giant aneurysms are similar with other aneurysms. Thrombosis of an aneurysm does not decrease the risk of bleeding. Progressive neurological symptoms can be seen in time due to mass effect. In these report, we did not visualized the vertebral artery which extends after the aneurysm. The patient did not accept operation. He has been followed for three years, in the follow up angiographies we detected no decrease in size and an increase in the thrombosed part of aneurysm. No deferioration in the neurological status of the patient was observed. Anahtar Kelimeler : Giant aneurysm, PICA aneurysm, thrombosed aneurysm
