Acute Sphenoparietal Sinus Thrombosis and/or Superficial Middle Cerebral Vein Thrombosis following Dental Extraction: A Case Report

The diagnosis and treatment of sphenoparietal sinus thrombosis remain challenging. The cases of sphenoparietal sinus thrombosis were rarely reported in literature. We aimed to present the diagnosis and treatment of sphenoparietal sinus thrombosis through a case study. A 42-year-old male patient initially presented with an acute moderate headache. Cerebral edema and hemorrhage in the drainage area of the superficial cerebral veins were confirmed in a CT scan. The absence of veins around Sylvian fissure and sphenoparietal sinus was found by cerebral arteriography. Thrombosis in the right sphenoparietal sinus was diagnosed and anticoagulant therapy was administered. The CT features and clinical symptoms fairly improved afterward. The most powerful and necessary evidence for the diagnosis of sphenoparietal sinus should be cerebral edema in the drainage area of the lateral fissure vein associated with sphenoparietal sinus thrombosis.
