A Case of Actinomycosis Involving Urachal Remnant / 대한비뇨기과학회지

We report a case of urachal actinomycosis. The patient presented with complaints of micturition pain and a left lower abdominal mass with pain. Magnetic resonance imaging(MRI) showed the mass extending from the dome of the bladder to just beneath the rectus muscle. Exploration revealed a hard mass in the urachal cord, which was attatched to a part of sigmoid colon and the dome of the urinary bladder and extended to the umbilicus. The mass, urinary bladder dome, sigmoid colon and urachal cord were resected, and histopathological revealed actinomycosis.
