Abstract:
Objective Inflammatory myofibroblastic tumor (IMT) is a rare condition. This report summarizes the characteristics of IMT in order to strengthen clinicians' understanding of this disease. Case Presentation A 59-year-old female patient presented with intermittent right flank and abdominal pain with fever for 1 month, and a right renal mass detected 3 weeks ago. The highest body temperature during the course of the illness was 39℃. She received symptomatic antiinfective treatment at another hospital for 2 weeks, and the symptoms were alleviated. Enhanced CT of the lower abdomen strongly suggested a right renal carcinoma, with multiple small lymph nodes in the peritoneal cavity and retroperitoneum. MRI indicated a neoplastic lesion in the right kidney, with suspicion of chromophobe cell carcinoma. Laparoscopic partial right nephrectomy was performed under general anesthesia, and the procedure was successful. Postoperative pathology showed that there was significant localized infiltration of lymphocytes and formation of lymphoid follicles, and the lymph nodes showed chronic inflammation. The final diagnosis was IMT. In the follow-up of 3 months, no tumor recurrence was observed. Conclusion IMT has a high misdiagnosis rate. When imaging findings are atypical for renal cell carcinoma, IMT should be suspected. The preferred treatment is laparoscopic partial nephrectomy.
