Postoperative developmental dural arteriovenous fistula

Summary Dural arteriovenous fistulas (DAVFs) are rare vascular abnormalities that comprise 10–15% of all intracranial arteriovenous malformations. Strong evidence suggests that the development of DAVFs in adults is acquired and may be caused by various factors, including sinus thrombosis, venous hypertension, trauma, and infection. We report a case of a 39-year-old woman with a left temporal hemorrhagic lesion and an associated developmental venous anomaly. The patient underwent craniotomy and surgery for the removal of the mass. Approximately 2 months postsurgery, the patient complained of left-sided tinnitus with a bruit over the left temporal region. Cerebral angiography showed a DAVF close to the operation site.
