Plain-English summary
A 16-year-old showjumping gelding was brought in for a check-up because he had a swelling in his back thigh that was growing slowly and didn’t seem to hurt him. He was also showing a slight limp when trotting. Various imaging tests, including X-rays and ultrasounds, didn’t show any clear issues in the thigh, but X-rays of his chest revealed unusual lumps in his lungs. After he passed away, a more detailed examination confirmed that he had anaplastic sarcoma, a type of aggressive cancer, in his thigh, but he never showed any signs of breathing problems during his illness.
Abstract
A 16-year-old showjumping gelding was examined because of a non-painful, slowly progressive caudal thigh swelling, which was associated with 2/10th lameness at the trot. Radiography, real time beta-mode ultrasonography and gamma-scintigraphy of the caudal thigh for the presence of chip fractures, sequestrum formation and, or, abscessation were inconclusive. Radiographic examination of the chest revealed multifocal, nodular cannon ball-like opacities throughout the entire lung fields from which a diagnosis of a primary soft tissue tumour with metastasis to the thorax was made. An anaplastic sarcoma was diagnosed port mortem in the candal thigh. At no time did the horse show signs of respiratory embarrassment.
