A 38-year-old man experienced dizziness and numbness in his right hand. Computed tomography revealed a subarachnoid hemorrhage in the precentral sulcus. T2-star-weighted MR images detected a thrombosis in the superior sagittal sinus (SSS) and in the cortical vein draining into the SSS. Based on these findings, we initiated an anticoagulant therapy at the early stage of the disease. In addition, protein S deficiency was found to be the cause of the cerebral venous thrombosis. Therefore, we continued administering the anticoagulant therapy to prevent a recurrence. In a case of an atypical subarachnoid hemorrhage, cerebral venous thrombosis as the cause of hemorrhage should be considered, which can be diagnosed using T2-star-weighted MR images.
