Epididymo-orchitis developing as a late manifestation of intravesical bacillus Calmette-Guerin therapy and masquerading as a primary testicular malignancy: a report of 2 cases.J Urol. 1992 Nov; 148(5):1534-5.JU
In 2 cases epididymo-orchitis, indistinguishable from a testicular tumor, developed as a late (15 and 34 months, respectively) complication following use of Tice strain bacillus Calmette-Guerin for treatment of superficial bladder carcinoma. In each instance the lesion was asymptomatic and ultrasonography demonstrated a complex scrotal mass. Inguinal orchiectomy was performed for diagnosis and therapy. The importance of obtaining a mycobacterial culture for further therapy planning is stressed.
