Summary
This case report details a rare instance of isolated cortical vein thrombosis in a 45-year-old man, presenting with seizures and hemiparesis. Prompt anticoagulation with heparin was initiated for this unusual cerebral venous thrombosis presentation.
Area of Science:
- Neurology
- Vascular Medicine
- Radiology
Background:
- Cerebral venous thrombosis (CVT) is a serious neurological condition.
- It often involves dural sinus thrombosis, but isolated cortical vein thrombosis is rare.
Observation:
- A 45-year-old male with a history of epilepsy presented with generalized seizures and subsequent right hemiparesis.
- Brain MRI showed abnormalities in the left frontal lobe and superior sagittal sinus.
- Cerebral angiography revealed a non-demonstrable left frontal cortical vein, despite a patent superior sagittal sinus.
Findings:
- Exploratory craniotomy confirmed an isolated cortical vein thrombosis.
- Laboratory data did not indicate factors typically associated with cerebral venous thrombosis.
- The patient was treated with heparin anticoagulation.
Implications:
- This case highlights the possibility of isolated cortical vein thrombosis, a rare variant of cerebral venous thrombosis.
- It underscores the importance of comprehensive neuroimaging and angiography in diagnosing CVT.
- The definitive etiology remains unknown, warranting further investigation into potential underlying causes.
