ABSTRACT
Gout is the most common form of microcrystalline arthropathy which usually does not pose a diagnostic challenge when patients have typical presentation, appropriate biochemical picture and classical radiographic appearance. However, formation of gouty tophi in unusual locations and with atypical presentations may mislead clinicians and radiologists, thereby justifying gout nickname as the "great mimicker". When interpreting images of tendon related masses, radiologists should be aware of gouty tophi as a possible differential given its variable and nonspecific imaging appearance. In this article, we present a case of a patient with a painless tophaceous gout nodule, adjacent to the Achilles tendon.

A large urothelial tumor was detected by ultrasonography in the dilated collecting system of a well-functioning renal allograft 15 years after transplantation. The tumor was confirmed at computed tomography. Nephrectomy showed a transitional cell carcinoma. The occurrence of malignant tumors in renal allografts is a well known but rare complication.

Selective and superselective renal embolization is a generally accepted technique for treating traumatic or iatrogenic renal arteriovenous fistulas or arteriocalyceal fistulas. Only a minority are pure arteriocalyceal fistulas. During embolization, an arteriovenous fistula may become a frankly bleeding arteriocalyceal fistula, causing massive haematuria and necessitating further embolization.
