Plain-English summary

A domestic shorthair cat developed weakness in all four legs and sensitivity in the lower back over four months. X-rays showed unusual masses in the soft tissue around the bones, which led to a diagnosis of osteochondromatosis, a condition where abnormal bone growth occurs. This cat's case was unique because many of the masses were not attached to the bone as seen in other cases. Unfortunately, the treatment options for this condition are limited, and the long-term outcome for the cat may not be favorable.

Abstract

A domestic shorthair cat was presented with quadriparesis and lumbar hyperesthesia that progressed over 4 months. There were linear and amorphous radiopaque masses throughout the soft tissue surrounding the long bones, vertebral bodies, ribs, pelvis, and scapula. The diagnosis of osteochondromatosis was confirmed by histopathology. Unlike previously reported patients with osteochondromatosis, most of the calcified masses in this cat were not connected to the periosteum; some were linear and were arranged parallel to the long bones involved.
