Chemical pericystitis: a rare complication of intravesical doxorubicin

We report a rare instance of chemical pericystitis in a 60-year-old man who had undergone transurethral resection of a bladder tumor and subsequent intravesical instillation of doxorubicin. The patient had a high fever lasting for 18 days, lower abdominal pain and mild hydronephrosis. Extravasation of doxorubicin through the resected and thinned region of the bladder wall seemed to be responsible for this complication. The lesion improved spontaneously without any sequela.
