Isolated Inferior Sagittal Sinus Thrombosis in Young Patient: Rare Case Report

Abstract

Cerebral venous thrombosis (CVT) is a less common type of stroke, mostly in young patients. The majority of these cases are due to thrombosis of superior sagittal sinus and transverse sinus. Isolated thrombosis of the inferior sagittal sinus is very rare. Here, we report a 22-year-old male patient with no significant past medical history who presented to the emergency department of our hospital with a convulsion, decreased level of consciousness, and right side weakness. His laboratory investigations, including the coagulation profile, were normal. A non-contrast brain CT showed a 5 × 3 cm hematoma in the left parasagittal parietal lobe with no associated midline shift or intraventricular extension. The cerebral magnetic resonance (MR) angiogram did not show any underlying aneurysm or vascular lesion. However, the cranial MR venogram showed inferior sagittal sinus thrombosis, while other cranial veins and dural sinuses were patent. The patient was admitted to the hospital and managed with low-molecular-weight heparin and warfarin sequentially. He had significant improvement (consciousness and weakness have improved, and seizures are under control). This present case illustrates a rare case of isolated cerebral venous thrombosis and also reviews the known literature on this condition.
