AI Article Synopsis
- Infectious granulomas in the kidney are uncommon, but cases exist involving conditions like tuberculosis and sarcoidosis; this report highlights a specific instance of a cryptococcal granuloma.
- An 80-year-old male with rheumatoid arthritis underwent cryotherapy for kidney cancer, and follow-up scans showed a mass that was initially thought to indicate cancer recurrence.
- After further investigation, the mass was identified as an infection-related granuloma, leading to a year-long antifungal treatment with positive results.
Article Abstract
Infectious granulomas arising in the kidney are rare. However, there are few reports regarding renal granulomas, such as xanthogranulomatous pyelonephritis, sarcoidosis, malakoplakia, and tuberculosis. Here, we report a case of cryptococcal granuloma resembling a locally progressed tumor after percutaneous cryotherapy for renal cell carcinoma. A male patient in his 80s with rheumatoid arthritis underwent computed tomography (CT)-guided cryoablation for biopsy-proven papillary renal cell carcinoma. Follow-up contrast-enhanced CT imaging obtained 4 months after ablation confirmed an enhanced mass on the edge of the ablation zone. There were no symptoms related to the mass. This mass was radiologically diagnosed as local tumor progression and treated with repeated cryoablation. Percutaneous biopsy of the mass was performed immediately after the second cryoablation, and the mass was pathologically diagnosed as granuloma related to infection. The patient was administered antifungal fluconazole for 1 year with a good outcome.
