This report aims to address the case of a calf presenting with Perosomus acaudatus associated with anal atresia. According to the owner, during the initial handling of the calf, observed the absence of the tail and anus. Subsequently, employees on the property performed a perforation in the perineal region. Upon being received by the Ruminant Clinic team at HVU-UFSM, the absence of the tail and anus was confirmed, with the presence of a healing wound in the perineal region and a longitudinal depression in the dorsal region of the pelvis. A radiographic examination revealed three non-fused sacral vertebrae and the absence of coccygeal vertebrae. Additionally, the colon and rectum were filled with gas. The owner was proposed to undergo surgical treatment for the correction of anal atresia. Due to adhesions of the rectum in the pelvic region, it was im possible to perform anoplasty. Instead, a colostomy was performed on the abdominal wall in the left inguinal region. After the procedure, the patient was able to defecate; however, in the following week, it exhibited apathy and prostration. A sample of peritoneal fluid was collected, revealing a change in color, turbidity, and an increase in nucleated cells. Given the findings, euthanasia was performed, followed by a necropsy of the animal. The observations included the absence of coccygeal vertebrae, the presence of only three sacral vertebrae, diffuse fibrinonecrosupurative peritonitis, diffuse transmural necrotizing colitis, and multifocal necrotizing dermatitis. The occurrence of Perosomus acaudatus, despite being rare, should always be closely examined to identify possible associated abnormalities. The outcome of this patient does not change the recommendation for surgical correction in cases of anal atresia.Downloads
