Learning objectives Illustrate the normal anatomy and anatomical variants of the cerebral venous system. Describe the key CT and MRI findings in cerebral venous thrombosis (CVT). Identify common false positives and pitfalls that may lead to diagnostic errors in CVT.
Read more Background  CVT is a rare but serious condition that requires rapid diagnosis for early treatment and improved prognosis.Risk factors: Pregnancy, postpartum, oral contraceptive use, thrombophilia, malignancy, infections, and dehydration.Clinical presentation: The clinical manifestations of CVT can be highly variable and often non specific, which may lead to diagnostic delays. The most common symptoms are described in the table 1. [fig 1] Given the heterogeneous and sometimes subtle clinical presentation, imaging plays a crucial role in early detection and confirmation of the diagnosis.Classification based on...
Read more Findings and procedure details Normal Anatomy, physiology, and anatomical variantsThe cerebral venous system plays a crucial role in draining deoxygenated blood from the brain parenchyma, maintaining intracranial pressure balance, and facilitating the clearance of metabolic waste. Unlike the arterial system, cerebral veins lack valves, allowing bidirectional flow and making them susceptible to thrombosis in states of altered haemodynamics.The cerebral venous system consists of: Dural venous sinuses: Superior sagittal sinus, transverse sinus, straight sinus. These large endothelial lined channels collect blood from the superficial and deep venous systems...
Read more Conclusion CVT is a rare but serious condition that requires timely diagnosis and management to prevent severe complications. Due to its non specific clinical presentation, imaging is fundamental for early detection and accurate classification. [fig 15]
