title: Enterovesical fistula caused by regressive change of non-Hodgkin's lymphoma: A case report.
abstract: Enterovesical fistula (EVF) is a rare complication of diverticulitis, as well as Crohn's disease, intestinal malignancy, radiotherapy and trauma. EVF formation is associated with inflammation of the involved bowel segments. The current study presents the case of a 35-year-old man with non-Hodgkin's lymphoma who developed pneumaturia, fecaluria and recurrent urinary tract infections following chemotherapy, accompanied by regressive change of the lymphoma. Abdominal computed tomography scans revealed that the terminal ileum had adhered to the bladder wall. The patient underwent exploratory laparotomy and partial resection of the terminal ileum, and EVF was confirmed. Histological examination revealed an inflammatory response but no evidence of residual lymphoma. The diagnosis of EVF is occasionally difficult and requires appropriate radiographic examination. Surgical treatment is recommended.
