Plain-English summary
An 8-month-old male Pit Bull Terrier was brought to the vet with firm swellings on his head and a lack of appetite for the past 3.5 days. After conducting scans and tests, the vet found abnormal bone growth in the dog's skull and jaw. The condition, which is not typically seen in this breed, was diagnosed as idiopathic canine juvenile cranial hyperostosis, a new term that combines features of two similar bone disorders. Treatment options were not specified, but understanding this condition can help guide future care for affected dogs.

Abstract
CASE HISTORY: An 8-month-old male Pit Bull Terrier was presented with bilateral firm swellings of the cranium in the region of the frontal sinuses. The dog was aggressive when approached and had also been anorexic during the 3.5 days prior to presentation. CLINICAL FINDINGS: Using computed tomography (CT) and radiology, periosteal new bone formation and hyperostosis were detected on the frontal, parietal and mandibular bones bilaterally. Histopathology of the calvarial and mandibular bones was similar, comprised of thick trabeculae of immature woven and mature lamellar bone separated by cementing lines. Sites of prominent osteoblastic and osteoclastic activity were also present. DIAGNOSIS: Craniomandibular osteopathy with clinical similarities to calvarial hyperostosis. CLINICAL RELEVANCE: Pit Bull Terriers are not predisposed to either craniomandibular osteopathy or calvarial hyperostosis. This observation, in addition to the clinical and pathological similarities between the two diseases, suggests that craniomandibular osteopathy and calvarial hyperostosis may represent a single disorder, with predilection sites that vary between breeds of dog. We propose a new term, idiopathic canine juvenile cranial hyperostosis, for this disorder, to include both craniomandibular osteopathy and calvarial hyperostosis.
