特发性肠系膜静脉硬化性肠炎（IMP）是比较罕见的疾病，临床上以腹痛、腹泻为主要表现，可伴有恶心、呕吐等非特异性症状。临床表现无特异性，有时诊断比较困难。CT的特征是肠系膜小静脉血管及其分支钙化，病理学上提示静脉壁的显著纤维化和钙化时可以确诊，目前其病因和发病机制尚不清楚。

Idiopathic mesenteric phlebosclerosis (IMP) is a relatively rare disease. Clinically, abdominal pain and diarrhea are the main manifestations of IMP, and may be associated with non-specific symptoms such as nausea and vomiting. Clinical manifestations of this disease are not specific, it was difficult to diagnose. The calcifications in mesenteric venous walls and their branches in computed tomography (CT) and significant fibrosis and calcification in mesenteric veins in pathological examinations are the characteristics for the diagnosis of IMP. The etiology and pathogenesis are still unclear.
