Idiopathic myointimal hyperplasia of the mesenteric veins: Case report and review of the literature

et al. 2019

In 1991, Genta and Haggitt described four patients with segmental ischemic colitis caused by idiopathic myointimal hyperplasia in the small mesenteric veins (IMHMV). There are now 33 published cases of IMHMV in the literature; however, this condition is still sufficiently rare that it poses a diagnostic challenge to pathologists and clinicians and is often clinically or histologically confused with inflammatory bowel disease (IBD) or ischemic colitis. IMHMV is characterized by intimal smooth muscle hyperplasia resulting in thickened small and medium‐sized mesenteric veins (with arterial sparing). Clinically, it presents with symptoms that mimic IBD, such as bloody diarrhea, abdominal pain, and weight loss. Surgical resection appears to be curative. The present case describes a 63‐year‐old Vietnamese man with cardiovascular risk factors who was diagnosed with IMHMV after many months of severe symptoms. A review of the current literature follows the case report.

“…The etiology of this nonthrombotic occlusion of mesenteric veins is poorly understood. First described by Genta and Haggitt in 1991, 33 reported cases of IMHMV have now been reported (Table ), and it is likely there are many more misdiagnosed or not reported.…”

Idiopathic myointimal hyperplasia of mesenteric veins (IMHMV) is a rare and poorly understood ischemic colitis that occurs in the rectosigmoid colon of predominantly young, previously healthy, male patients. A 76-year-old Japanese man presented to our hospital with a 1-year history of worsening diarrhea, lower abdominal pain, and weight loss (-6 kg). Laboratory evaluation revealed white blood cell count of 13,200/μL, C-reactive protein level of 2.0 mg/dL (normal range, 0.0-0.3), and negative results for stool culture (including Clostridium difficile). Colonoscopy showed circumferential and edematous narrowing of the sigmoid colon with deep longitude ulceration. Biopsy was done and examination of the specimen demonstrated no specific ischemia. The patient was treated with bowel rest, antibiotics, and i.v. fluids; however, his symptoms worsened. Finally, sigmoidectomy was carried out. Histological examination demonstrated significant myointimal hyperplasia of mesenteric veins leading to thickening and stenosis of the venous lumen. Therefore, the final diagnosis was IMHMV. Three months following sigmoidectomy, he was asymptomatic.

“…Endoscopic findings include inflammation, ulceration and pseudopolyposis, usually restricted to the sigmoid colon. Initial biopsies are often non‐specific or may suggest an ischaemic aetiology to the presentation …”
