Imaging Diagnosis—magnetic Resonance Imaging Features of Craniomandibular Osteopathy in an Airedale Terrier

Abstract

An Airedale Terrier was presented for evaluation of depression and reluctance to be touched on the head. Magnetic resonance (MR) imaging of the head was performed. The images revealed bone lesions affecting the calvarium at the level of the coronal suture and left mandibular ramus, with focal cortical destruction, expansion, and reactive new bone formation. Skull lesions were hypointense on T1-weighted sequences, hyperintense on T2-weighted sequences, and showed an intense and homogeneous enhancement after gadolinium administration. Reactive new bone formation and periosteal proliferation were confirmed histopathologically. The clinical signs, imaging findings, and histopathological examination were consistent with craniomandibular osteopathy.

Surgical management of chronic otitis secondary to craniomandibular osteopathy in three West Highland white terriers

“…, Matiasovic et al . ). Affected dogs are typically presented at 3 to 9 months of age because of a painful jaw swelling, episodic pyrexia, lethargy and inappetance (Riser et al .…”

“…Concurrent involvement of other skull and long bone metaphyses is occasionally reported (Riser et al 1967, Dennis et al 1993, Watson et al 1995, Franch et al 1998, Ratterree et al 2011, Thompson et al 2011, Pettitt et al 2012. West Highland white terriers (WHWT), Scottish terriers and Cairn terriers are at increased risk of developing CMO (Munjar et al 1998, LaFond et al 2002, although numerous other breeds have been affected sporadically (Watkins & Bradley 1966, Watson et al 1975, Burk & Broadhurst 1976, Schulz 1978, Hathcock 1982, Taylor et al 1995, Franch et al 1998, Munjar et al 1998, Huchkowsky 2002, Ratterree et al 2011, Thompson et al 2011, Matiasovic et al 2015. Affected dogs are typically presented at 3 to 9 months of age because of a painful jaw swelling, episodic pyrexia, lethargy and inappetance (Riser et al 1967, Dennis et al 1993.…”

Craniomandibular osteopathy in a golden jackal (Canis aureus)

“…No data describing this disease in other species are available. Canine CMO most commonly occurs in West Highland white terriers, and it has also been described in other breeds, including Scottish terriers, Airedale terriers, Akitas, labrador retrievers, Great Danes, bullmastiffs, Doberman pinschers, cairn terriers, Pyrenean mountain dogs, boxers, Boston terriers, Deutsch Drahthaar dogs and an English bulldog 3–19…”

“…In addition to clinical features, imaging modalities such as radiography, CT and MRI play an important role in the assessment of the lesions. Radiographs show hyperostotic features with symmetrical enlargement on the skull and long bones, lesions that are most commonly seen on the mandibles and tympanic bullae but which may occur independently 12 14 16–18…”

Osteopatía craneomandibular en un canino mestizo

“…En casos avanzados se observa aumento considerable del tamaño de la mandíbula, disminución del rango de movimiento de la articulación temporomandibular, disminución de la ingesta de alimento y baja de peso (Huchkowsky, 2002; Montgomery y Simmons 2012). Ha sido reportada tanto en razas pequeñas como grandes, habiendo una mayor predisposición en el Scottish Terrier, West Highland White Terrier, Boston Terrier y Cairn Terrier (Padgett et al, 1986;Matiasovic et al, 2015).…”
