Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare cause of chronic colonic ischemia characterized by intimal smooth muscle proliferation and luminal narrowing of the small to medium sized mesenteric veins. It predominantly affects the rectosigmoid colon in otherwise healthy, middle-aged males. Definitive diagnosis and treatment are surgical; however, patients are frequently misdiagnosed, which often results in a protracted clinical course. We describe a case of IMHMV presenting as left hemicolitis in a 53-year-old male, as well as the endoscopic, histopathologic, and radiographic findings that established the diagnosis.
特发性肠系膜静脉内膜增生症（IMHMV）是一种罕见的慢性结肠缺血病因，其特征为内膜平滑肌增生和中小肠系膜静脉管腔狭窄。它主要影响健康中年男性的直肠乙状结肠。明确的诊断和治疗是手术；然而，患者经常被误诊，这往往导致病程延长。我们描述了一例以 53 岁男性左侧结肠炎为表现的 IMHMV 病例，以及内镜、组织病理学和影像学检查结果，这些结果确立了诊断。
