Cranioplasty after en bloc resection of calvarial chondroma rodens in two dogs.

The clinical features of chondroma rodens in two dogs and the treatment using radiation therapy, en bloc resection of the tumours and cranioplasties with a bone allograft (case 1) and a polymethylmethacrylate implant (case 2) are described. The dogs were still alive with no local recurrence of the tumours 30 and 18 months, respectively, after surgery. En bloc resection and calvarial reconstruction in the treatment of chondroma rodens are discussed.
