Conclusion
We describe a case of spontaneous mesenteric haematoma in a female patient suffering from an exacerbation of Crohn's disease and intestinal stenosis. The mesenteric haematoma was identifiable both on pre-operative computerised tomography and intra-operatively. This case identifies the first association of spontaneous mesenteric haematoma with an exacerbation of Crohn's disease and highlights the need to consider rare differential diagnoses such as SMH when performing radiological assessment of unexplained symptoms in inflammatory bowel disease patients.
