RESUMO

Traumatic neuroma results from regeneration attempts of the proximal end of an injured or severed nerve, resulting in a non-neoplastic nodular lesion. The lower extremity after amputation is the most common site, followed by the head and neck. Traumatic neuromas occurring in the abdomen, however, are rare. In the abdominal region, traumatic neuromas occur in the cystic duct stump and the common bile ducts as well as around the celiac trunk. This study reports a case of a 59-year-old man who presented with a traumatic neuroma arising at the stump of the inferior mesenteric artery after rectal cancer surgery. Traumatic neuromas at the stump of the inferior mesenteric artery have not been previously reported. The lesion exhibited atypical imaging features, including a well-enhanced nodule, a significant interval growth in size and a mild increase in 18F-fluorodeoxyglucose uptake, resembling lymph node metastasis. This case report will help physicians understand the sites of occurrence and imaging features of traumatic neuromas in the abdomen.
