Abstract
Background: Gastrointestinal hemangiomas are very rare and are even rarer in the mesentery. It is not known whether they originate in the bowel wall or the mesentery currently. Some studies have described mesenteric hemangiomas that originate in the bowel wall and extend into the mesentery. We herein describe a case of cavernous hemangioma of the mesorectum. Case presentation: A 31-year-old male presented with hematochezia and sensation of rectal tenesmus. Both the rectal MRI and contrast-enhanced CT scan of the whole abdomen indicated rectal wall thickening, marked dilated and tortuous vessels around the rectum. In addition, an anomalous vein had arisen from the superior mesenteric vein, extending down to the mesorectum. The patient underwent laparoscopic surgical resection of the mesorectal lesion and the involved portions of the rectum. The surgical samples underwent pathological analysis, and a diagnosis of mesenteric cavernous hemangioma was confirmed. Seven days after surgery, the patient was discharged without postoperative complications.Conclusion: Mesenteric hemangiomas are extremely rare tumors. In our present case, an anomalous vein had arisen from the superior mesenteric vein, extending down to the mesorectum. This findings suggest that the mesenteric hemangioma more likely originated in the mesentery.
