Case Report
A 70-year-old male, affected by hypertension, hyperlipidemia, and ischemic heart disease, presented to the emergency department with a history of lumbar pain radiating bilaterally to the back lasting from about 1 week. The patient's history showed subsequent transurethral resections (10 and 5 months before) and intravesical BCG therapy (3 months before) as treatment for bladder transitional cell carcinoma. Two months apart, due to biopsy-proven residual high-degree transitional papillary cell
Discussion
Intravesical BCG instillation therapy is the treatment of choice for early-stage transitional cell bladder cancer with reported cure rates of 70%.3 Although it is a well-tolerated treatment, systemic reactions such as fever, malaise, hepatitis, and pneumonia have been described.3, 4 Vascular complications such as mycotic aneurysms occur in less than 1% of cases.5 In literature, less than 30 cases of MB-related mycotic aneurysms are reported.6, 7 The presence of mycotic aneurysms, similar to
