Summary: IMHMV is a rare cause of ischemic bowel disease, characterized by proliferation of smooth muscles in mesenteric veins. Pre-operative CT with specific imaging features such as continuous concentric thickening of the colonic wall, poor enhancement, and enlarged tortuous pericolic arteries can facilitate rapid diagnosis of IMHMV.

Summary: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare and poorly understood disease characterized by non-thrombotic and non-inflammatory occlusion of the mesenteric veins. Its etiology is unknown and it presents with symptoms such as abdominal pain, bloody diarrhea, and weight loss. IMHMV is often misdiagnosed as inflammatory bowel disease, highlighting the need for increased awareness among clinicians.

Summary: In this study, clinical, radiologic, and endoscopic findings in 124 patients with idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) were examined in order to provide clinicians with a framework for pre-surgical identification of this rare disease.

Summary: IMHMV is a rare disease caused by proliferation of smooth muscle cells in mesenteric veins, leading to venous ischemia. This report describes a case of colonic ischemia in a 63-year-old man due to IMHMV.

Summary: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare cause of chronic colonic ischemia characterized by smooth muscle proliferation and narrowing of the mesenteric veins. It mainly affects the rectosigmoid colon in middle-aged males. Diagnosis and treatment require surgery, but misdiagnosis is common, leading to prolonged clinical course. We present a case of IMHMV presenting as left hemicolitis in a 53-year-old male, with endoscopic, histopathologic, and radiographic findings confirming the diagnosis.

Summary: This study aimed to systematically evaluate the surgical procedures and outcomes for patients with idiopathic myointimal hyperplasia of the mesenteric veins. The majority of patients achieved remission with surgical intervention, with surgical resection being the most commonly performed procedure. Surgical decision-making should consider the extent of the disease.

Summary: Idiopathic myointimal hyperplasia of mesenteric veins (IMHMV) is a rare type of chronic colonic ischemia. It often mimics inflammatory bowel disease and surgical resection is the curative treatment.

Summary: In this case report, a male patient with idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) and a presumed history of ulcerative colitis was described. The incorrect diagnosis of ulcerative colitis based on radiological findings led to unnecessary treatment with immuno-modulators and poor treatment response. Physicians should consider the possibility of IMHMV in cases with suspected inflammatory bowel disease or non-occlusive ischemia of the distal colorectum to prevent misdiagnosis and inappropriate treatment.

Summary: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare and poorly understood noninflammatory ischemic colitis. It is frequently misdiagnosed as an inflammatory bowel disease and is characterized by chronic abdominal pain, weight loss, and diarrhea. The pathophysiology involves the proliferation of the intimal smooth muscle in mesenteric veins, leading to bowel ischemia. Surgical resection is typically required for diagnosis as there are no effective medical therapies.

Summary: A 71-year-old man presented with abdominal pain and constipation, leading to a diagnosis of idiopathic myointimal hyperplasia of mesenteric veins (IMHMV). He underwent laparoscopic resection and histologic examination confirmed the diagnosis.

Summary: This retrospective observational study investigated the clinical features of 12 cases of idiopathic myointimal hyperplasia of the mesenteric veins. The radiologic and pathologic characteristics were found to be distinct from those of ulcerative colitis or nonspecific ischemic colitis. The study suggests that careful interpretation of endoscopic and radiologic images, as well as generous biopsies with interpretation by experienced pathologists, might lead to an early diagnosis and prevent unnecessary medical treatment.

Summary: Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is a rare ischemic bowel disease that often requires surgery for precise diagnosis. This case report describes a successful surgical treatment of an 81-year-old female patient with IMHMV, who remained well without additional medication during a two-year and 8-month follow-up.
