Abstract

This case report describes successful surgical removal of large intra pelvic fibromas in two dogs. One was an eight-year-old mixed breed female dog presented with a vaginal mass which was palpable on digital rectal examination. It extended from the vagina to the pelvic brim. A CT scan was performed which defined the extent of the mass clearly. The other case was a ten-year-old mixed breed female dog presented with a mass palpable in the pelvic canal. Both the cases were confirmed to be a fibromas by fine needle aspirate. As complete excision of the masses was unmanageable through either midline or vaginal approach, they were successfully resected through bilateral pubic and ischial osteotomy approach. An ovariohysterectomy and partial vaginectomy was performed in the first dog at Veterinary Teaching Hospital, Madras Veterinary College, Chennai, India and an ovariohysterectomy was performed in the second dog at Veterinary Teaching Hospital, School of Veterinary Medicine, Trinidad and Tobago.
