Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare entity reported in adults, frequently mimicking inflammatory bowel disease (IBD). We report the first case of intestinal ischemia secondary to IMHMV presenting as IBD in a pediatric patient with Down syndrome. Chronic intestinal ischemia is rare in children, and this case emphasizes the need to consider this in the differential, when histopathology is suggestive.

Article Synopsis
- The study explores rare vascular diseases (Behçet disease, enterocolic lymphocytic phlebitis, idiopathic myointimal hyperplasia of mesenteric veins, and mesenteric arteriovenous dysplasia) that can cause bowel ischaemia and are often misdiagnosed as Crohn's disease due to similar symptoms and histological patterns.
- Researchers compared clinical and pathological data of 13 patients misdiagnosed with Crohn's disease and later found to have these vascular diseases against a control group of 15 patients who were correctly diagnosed with Crohn's.
- Key distinguishing features were identified: Crohn's disease showed signs like transmural inflammation and abscesses, while

Background: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare condition that poses a diagnostic challenge to surgeons and pathologists alike. Our aim is to describe two cases of IMHMV requiring operative intervention. The challenge going forward is accurately and systematically identifying factors from both a pathologic and clinical perspective that guide timely diagnosis and avoid unnecessary treatment.

Article Synopsis
- * After worsening symptoms a month later, CT angiography revealed changes suggesting the presence of an arteriovenous fistula (AVF) in the mesentery, alongside continuing ischaemia and necrosis of the bowel.
- * Emergency surgery led to a diagnosis of idiopathic myointimal hyperplasia of mesenteric veins (IMHMV), characterized by specific CT findings, requiring bowel resection due to the damaging effects of this non-thrombotic venous obstruction.
