Primary malignant lymphoma of the urinary bladder is extremely rare, and to our knowledge, no case described in the radiologic literature has been accompanied by calcification. We report a case in which the condition was associated with calcification, and describe the pelvic CT and MR imaging findings.

Vesicoenteric fistula is a rare complication of bladder squamous cell carcinoma. We report the case of a 70-year-old male who complained of painless, total gross hematuria. Abdominopelvic computed tomography (CT) revealed an approximately 2.7-cm lobulated and contoured enhancing mass in the bladder dome. We performed partial cystectomy of the bladder dome after transurethral resection of the bladder. The biopsy result was bladder squamous cell carcinoma, with infiltrating serosa histopathologically, but the resection margin was free. Postoperatively, follow-up CT was done after 3 months. Follow-up CT revealed an approximately 4.7-cmx4.0-cm lobulated, contoured, and heterogeneous mass in the bladder dome. A vesicoenteric fistula was visible by cystography. Here we report this case of a vesicoenteric fistula due to bladder squamous cell carcinoma.
