title: Surgicel granuloma: unusual cause of "recurrent" mass lesion after laparoscopic nephron-sparing surgery for renal cell carcinoma.
abstract: We present the first clinical report of Surgicel granuloma after laparoscopic nephron-sparing surgery and present the characteristics of this radiological image mimicking local recurrence. A 47-year-old man underwent laparoscopic nephron-sparing surgery for left renal interpolar incidentaloma; Surgicel bolsters were used for hemostasis. Histological examination revealed conventional clear-cell renal cell carcinoma with negative surgical margins. Magnetic resonance imaging at 3 months revealed a 2.5-cm enhancing mass in the region of nephron-sparing surgery. Computed tomography-guided core biopsy revealed foreign-body granuloma. Serial magnetic resonance imaging showed a decrease in the size/enhancement of the lesion during 12 months. To conclude, Surgicel may invoke foreign-body reaction leading to formation of pseudotumor, which leads to diagnostic dilemma.
