Unusual Case of Cerebral Venous Thrombosis in Patient with Crohn's Disease

Area of Science:

• Neurology
• Gastroenterology
• Hematology

Background:

• Crohn's disease (CD) is associated with an increased risk of hypercoagulable states, potentially leading to complications like cerebral venous thrombosis (CVT).
• While CVT is considered a rare complication of CD, its development is often linked to active disease states.

Observation:

• A 17-year-old male with a history of CD, managed with mesalazine and azathioprine, presented with acute neurological deficits including right-sided weakness and hypesthesia.
• Brain MRI revealed acute infarction and cortical subarachnoid hemorrhage. Magnetic resonance venography identified a filling defect in the superior sagittal sinus, indicative of CVT.
• The patient exhibited no symptoms of active CD flare-up, such as bloody stools, abdominal pain, or weight loss.

Findings:

• This case demonstrates CVT occurring in a patient with Crohn's disease during a period of clinical remission.
• The findings suggest that the underlying Crohn's disease pathology, independent of active inflammation, may contribute to the hypercoagulable state leading to CVT.

Implications:

• The risk of CVT in Crohn's disease patients may persist even in the absence of active disease.
• This highlights the importance of considering CVT in CD patients presenting with neurological symptoms, regardless of their current disease activity status.
• Further research is warranted to elucidate the specific mechanisms linking Crohn's disease to CVT outside of active disease phases.
