Intracranial dural arteriovenous fistulas (DAVFs) are typified by pathological anastomoses between meningeal arteries and dural venous sinuses or cortical veins. There are many causes contributing to the etiology of DAVFs. Among the variable causes, acquired DAVFs secondary to craniotomy had rarely been reported, especially for delayed DAVFs at the transverse-sigmoid sinus. Till now, there are only 12 published cases of delayed DAVFs at the transverse-sigmoid sinus secondary to craniotomy. Herein, the authors describe such an extraordinary rare case secondary to petroclival meningioma resection via far lateral approach, and to the best knowledge of us, this is the first well-documented case of delayed DAVF at the transverse-sigmoid sinus following far lateral craniotomy. Furthermore, cases of delayed DAVFs at the transverse-sigmoid sinus secondary to craniotomy were reviewed and investigated, and the clinical characteristics and treatment were also broadly discussed.
