Plain-English summary
An 8-year-old female Labradoodle was brought to the vet because she was restless and unable to stand. An ultrasound showed a large mass in her abdomen, and a CT scan revealed that it was an extraskeletal osteosarcoma, a type of cancer that developed due to a surgical sponge left inside her body. The dog underwent surgery to remove the mass, but unfortunately, four months later, she developed lung metastases and had to be euthanized.

Abstract
An 8-year-old neutered female Labradoodle presented with acute restlessness and inability to stand. Point-of-care ultrasound revealed a large abdominal mass, prompting further imaging. Computed tomography (CT) demonstrated a mass with marked mineralization, a thick, enhancing rim, and signs of intra-abdominal dissemination. Surgical excision of the mass was performed, and histopathology confirmed extraskeletal osteosarcoma (ESOSA) secondary to a retained surgical sponge (gossypiboma). Four months post-surgery, the dog developed pulmonary metastases and was euthanized. This report is the first to describe CT findings of ESOSA secondary to a retained surgical sponge in a dog.
