Subdural empyema in the adjacent cortex of an arteriovenous malformation [Arteriovenöz malformasyona komşu beyin korteksi Üzerinde subdural ampiyem]

Background: the coexistence of arteriovenous malformation and subdural empyema is extremely rare. case report: a 40-year-old man was admitted with a severe headache. his cranial computerized tomography findings showed a right-sided temporal intracerebral hematoma with a midline shift. during surgery,an organized capsule and subdural empyema,which contained pus and trabeculae,were seen as the dura was elevated. after resection of the infectious tissue,the intracerebral hematoma was reached and evacuated,and the nidus of the arteriovenous malformation (avm) was resected. the recovery was uneventful. herein,we discuss the formation mechanism of empyema,together with the avm in the same hemisphere,and the possible role of the hemodynamic and ischemic processes associated with the steal phenomenon. additionally,we present the proliferative and inflammatory roles of the molecular biological factors; vascular endothelial growth factor (vegf) and basic fibroblastic growth factor (bfgf) promoting angiogenesis in avm. conclusion: additionally,we present the proliferative and inflammatory roles of the molecular biological factors; vascular endothelial growth factor and basic fibroblastic growth factor promoting angiogenesis in avm. © 2015,ege university press. all rights reserved.
