Can near-infrared imaging distinguish a gelatin-based matrix granuloma from a malignancy in a kidney?

Differentiating granulomas from cancerous tissue poses a significant challenge in upper urinary tract surgery. We present the case of a 62-year-old male with a gelatin-based matrix (Surgiflo ) granuloma in the kidney following renal cyst decortication eight years earlier. Contrast-enhanced abdominal...

Description
Summary:Differentiating granulomas from cancerous tissue poses a significant challenge in upper urinary tract surgery. We present the case of a 62-year-old male with a gelatin-based matrix (Surgiflo ) granuloma in the kidney following renal cyst decortication eight years earlier. Contrast-enhanced abdominal tomography revealed a Bosniak type-4 cyst at the previous operation site. The patient underwent laparoscopic partial nephrectomy with near-infrared imaging. The lesion presented as hypofluorescent relative to normal kidney tissue. Histopathological examination revealed a foreign body granuloma due to unabsorbed Surgiflo. The fluorescence pattern could not distinguish a Surgiflo granuloma from a malignant lesion of the kidney.
