Sigmoid sinus thrombosis in an elderly client with chronic varicose vein in the leg: a case report

Dehydration and malignancies are known as the most frequent predisposing factors of cerebral venous sinus thrombosis in older adults despite the fact that 30% of them remain idiopathic cerebral venous thrombosis (CVT) cases with no clear etiology. Cases of left sigmoid sinus involvement were rarely reported. Herein, an elderly case of sigmoid sinus thrombosis with unilateral hearing loss with chronic varicose vein in the leg was reported. Sigmoid sinus thrombosis that affects hearing is one of the rare complications of otitis media. Whether or not a large chronic varicose vein in the leg can serve as a predisposing factor for CVT requires further studies. Successful management of anticoagulant therapy prevented serious complications in the patient.
