Regression of hypertrophic osteopathy in a cat after surgical excision of an adrenocortical carcinoma.

Department of Small Animal Clinical Sciences, School of Veterinary Medicine, Michigan State University, East Lansing 48824, USA.

A 12-year-old, spayed, female domestic shorthair cat was diagnosed with severe and extensive hypertrophic osteopathy of the appendicular skeleton. Diagnostic ultrasound detected a mass lesion in the right adrenal gland. A right adrenalectomy was performed, and histopathological examination confirmed an adrenocortical carcinoma. No radiographic evidence of pulmonary metastasis was found on initial presentation or recheck thoracic radiographs taken 15 weeks later. Almost complete regression of periosteal new bone formation occurred 15 weeks following the successful surgical removal of the adrenal tumor.
