Summary
A rare case of aseptic cortical venous thrombosis occurred in a woman with ulcerative colitis, presenting as cerebral hemorrhage. This finding suggests a potential link between ulcerative colitis and isolated cerebral venous thrombosis.
Area of Science:
- Neurology
- Vascular Medicine
- Gastroenterology
Background:
- Aseptic cortical venous thrombosis is uncommon, typically occurring with dural sinus thrombosis.
- Ulcerative colitis is a known risk factor for both dural sinus thrombosis and isolated cortical venous thrombosis.
Observation:
- A 26-year-old woman with ulcerative colitis experienced a spontaneous cerebral hemorrhage.
- Spin-echo MRI revealed a thrombosed cortical vein overlying the hemorrhage.
- Angiography confirmed the presence of the thrombosed cortical vein.
Findings:
- The signal characteristics of the thrombosed cortical vein were consistent with those observed in dural sinus thrombosis.
- This case highlights the possibility of isolated cortical venous thrombosis in patients with ulcerative colitis.
Implications:
- This case expands the understanding of cerebrovascular complications associated with ulcerative colitis.
- It underscores the importance of considering cerebral venous thrombosis in ulcerative colitis patients presenting with neurological symptoms.
- Further research may elucidate the specific mechanisms linking ulcerative colitis to isolated cortical venous thrombosis.
