Utility of 67Ga scintigraphy in disseminated infection after BCG instillation for treatment of bladder carcinoma.

Intravesical instillations of bacille Calmette-Guérin (BCG), an attenuated live strain of Mycobacterium bovis, is the treatment of choice for superficial bladder cancer. Local side effects are frequent, although adverse systemic reactions are uncommon, but more serious. We present 2 patients who developed disseminated M. bovis infection with multiorgan involvement after intravesical BCG therapy. (67)Ga scintigraphy was very helpful for the diagnosis as the only imaging tool with pathological findings.
