Summary
Deep cerebral venous thrombosis (DCVT) is a rare condition. MRI and CT imaging effectively detect DCVT, with MRI showing high signals in deep veins and revealing venous infarcts.
Area of Science:
- Neurology
- Radiology
- Vascular Medicine
Background:
- Deep cerebral venous thrombosis (DCVT) is a rare but serious neurological condition.
- Early and accurate diagnosis is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the diagnostic utility of CT and MRI in detecting deep cerebral venous thrombosis.
- To assess the imaging findings and follow-up of DCVT patients.
Main Methods:
- Retrospective analysis of eight patients with DCVT.
- Utilized CT, MRI, CT angiography, MR angiography (MRA), and digital subtraction angiography (DSA).
- Assessed direct and indirect signs of thrombosis and parenchymal involvement.
Main Results:
- CT showed a "cord sign" in five patients and infarcts in three.
- MRI revealed high signal intensity in deep veins in all patients and infarcts in five.
- Imaging modalities (CT, MRI, MRA, DSA) showed concordant findings for thrombosis.
- Follow-up MRI demonstrated progressive venous recanalization.
Conclusions:
- CT and MRI are valuable tools for diagnosing deep cerebral venous thrombosis.
- MRI is particularly sensitive for detecting DCVT and associated infarcts.
- Imaging findings correlate with clinical presentation and can show recanalization over time.
