Ruptured cerebral aneurysm is the most common cause of non-traumatic subarachnoid hemorrhage. Subsequent to this catastrophe, patients have usually evidence of severe headache with sudden onset, signs of meningeal irritation, and depression of consciousness. Difficulties in diagnosis arise when the clinical picture is not classical. Cerebral vasospasm following aneurysmal subarachnoid hemorrhage is the leading cause of death and disability after aneurysm rupture. In the presence of a typical history and a normal CT scan, lumbar puncture should be performed with spectrophotometry analysis of the supernatant. After subarachnoid hemorrhage has been confirmed, four-vessel angiography should be performed as soon as possible. The surgical treatment of subarachnoid hemorrhage caused by ruptured aneurysm is the method of choice.

Ruptured cerebral aneurysm is the most common cause of spontaneous subarachnoid hemorrhage (SAH). Rarely cerebral venous sinus thrombosis (CVST) may present initially as acute SAH, and clinically mimics aneurysmal bleed. We report 2 cases of CVST who presented with severe headache associated with neck pain and focal seizures. Non-contrast brain CT showed SAH, involving the sulci of the convexity of hemisphere (cSAH) without involving the basal cisterns. Both patients received treatment with anticoagulants and improved. Awareness of this unusual presentation of CVST is important for early diagnosis and treatment. The purpose of this paper is to emphasize the inclusion of vascular neuroimaging like MRI with venography or CT venography in the diagnostic workup of SAH, especially in a patient with strong clinical suspicion of CVST or in a patient where neuroimaging showed cSAH.
