Surgical treatment of a post‐traumatic osteoma in a 3‐year‐old German shepherd dog

A 3‐year‐old German shepherd dog presented with a frontal mass. The dog had experienced trauma before the onset of swelling and subsequent mass growth. Computed tomography revealed a bone‐like mass originating from the frontal bone. A craniectomy was performed to excise the mass. Histopathological features were suggestive of a benign bone‐forming lesion or osteoma. While osteomas without evidence of trauma are a rare but reported condition in veterinary medicine, trauma‐related osteomas have been described in human medicine. The surgical procedure was successful, and at 18‐month follow‐up, there was no evidence of recurrence. To the authors’ knowledge, post‐traumatic osteoma of the frontal bone has not been previously documented in dogs. It underscores the importance of considering this benign condition in the differential diagnosis of patients presenting with bone‐like masses of the skull following a trauma.
