title: Calcinosis circumscripta of the thoracic wall in a German shepherd dog.
abstract: Calcinosis circumscripta of the left thoracic wall was diagnosed in a six-month-old, female German shepherd dog by thoracic radiography and ultrasonographic-guided biopsy. The puppy developed the lesion following a left thoracotomy to repair a patent ductus arteriosus. Complete resolution occurred following surgical excision of the lesion. Calcinosis circumscripta associated with routine surgical manipulation and postoperative inflammation has been reported rarely but should be suspected when a focal, mineralized lesion occurs at a previous surgical site, especially in German shepherd dogs.
