A three month-old Mangalarga Marchador colt, that eliminated urine in jets through the penian urethra, anus and through four fistulae in the perianal area. Post-mortem examination revealed that the fistulae communicated the pelvic urethra and the bladder to the rectum and the rectum and the pelvic urethra to the perianal area. Additionally, there were cecorectal fistula, persistence of the urachus and dilatation of the pelvic urethra, with a ventral blind sack. The bladder was filled with caseous exudate and feces and showed adherences with the peritonium, ileum and cecum, as well as with the muscles of the abdominal wall. This malformation type still had not been described in equine in Brazil.
