Partial nephrectomy(PN)is primarily used to treat small size renal cell carcinoma(RCC),aiming to minimize the impact on kidney function.Although the recurrence rate post-PN is low,vigilance in diagnosing recurrence is crucial to differentiate it from inflammatory pseudotumor(IPT)and therefore prevent unnecessary interventions.In the case of a 56-year-old female patient who underwent PN for RCC of the right kidney,a mass was identified in the original surgical site over a year later,raising concerns of local recurrence based on imaging findings.However,when the patient declined puncture biopsy,a Radical Nephrectomy(RN)was performed instead.Subsequent pathology results revealed the presence of IPT,not tumor recurrence.This case underscores the importance of a comprehensive analysis of imaging features to accurately diagnose postoperative recurrence following PN.Where uncertainty persists,puncture biopsy should be considered to provide a definitive diagnosis.Moreover,emphasizing ongoing training in PN techniques and adherence to established protocols is essential to minimize the likelihood of complications such as trauma and infection,thereby reducing the occurrence of both postoperative PN recurrence and IPT.
