Learning objectives To review the causes and pathophysiology of cerebral venous thrombosis (CVT) as a means to know when to expect it, and to recognize radiological appearances on CT.The purpose is to establish diagnostic confidence in an emergency setting, since early diagnosis and treatment are crucial.
Read more Background CVT represents 1-2% of strokes in adults. Mortality rates ranges between 5-30%, with several studies showing mortality rate of up to 50% in untreated patients. CVT involves thrombosis in dural venous sinuses, cortical veins or deep cerebral veins. The poor outflow leads to congestion and blood–brain barrier disruption resulting with vasogenic edema.  Almost 50% of cases will also develop parenchymal hemorrhage due to rapid rise of venous pressure leading also to cytotoxic edema and infarction.It is much more prevalent in young...
Read more Findings and procedure details CT is always the initial imaging tool to rule out any neuropathology. Being familiar with CT imaging findings is of great importance for establishing diagnostic confidence in order to prevent acute complications and non-reversible consequences.Non-contrast CT (NECT) is the starting point for suspected CVT. Direct signs include hyperdense vein - the "cord sign" in case of cortical vein thrombosis, usually combined with expanded, hyperdense sinus which is indicative of thrombus presence in the venous sinus. (Figure.1)Indirect signs as sulcal effacement...
Read more Conclusion CT is the first and many times the only tool in emergency setting. It offers many clues to the diagnosis of CVT, which is vital for prompt treatment, helping prevent complications and irreversible outcomes.
