“…Although common imaging characteristics for all mass types were identified, individual tumor types of this sample group had more specific imaging findings. Previously reported information on the imaging characteristics of canine odontogenic tumors is limited primarily to case or case series reports and brief textbook descriptions . To the authors’ knowledge, a blinded study of the imaging characteristics of these tumors incorporating a board‐certified veterinary radiologist has not been previously performed.…”

“…There was only one compound odontoma in this study and it contained hyperattenuating tooth‐like material with areas suggestive of enamel. The radiographic characteristics of canine compound odontomas have been extensively described in multiple case reports and case series and mass associated tooth‐like material is a trademark Roentgen sign of these tumors . These masses are also often associated with impacted or unerupted teeth and mass‐associated cyst‐like structures have been described …”

Odontogenic neoplasms are locally invasive oral tumors in dogs. The purpose of this retrospective study was to describe CT characteristics for varying histopathologic types of canine odontogenic neoplasms. A boardcertified veterinary radiologist who was unaware of histologic findings reviewed and scored imaging studies. A total of 29 dogs were included in the study. Twenty-three of these dogs had concurrent dental radiographs. The most common CT characteristics for all tumor types were a direct association with or in the region of multiple teeth in 96.4% (27/28), contrast enhancement in 96.3% (26/27), alveolar bone lysis in 93.1% (27/29), and mass-associated tooth displacement in 85.2% (23/27). Mass-associated cyst-like structures were identified in 53.6% (15/28) and were only present in tumors containing odontogenic epithelium. Canine acanthomatous ameloblastomas (n = 15) appeared as extra-osseous (10/15) or intra-osseous (5/15) masses. Intra-osseous canine acanthomatous ameloblastomas were more likely to have mass-associated cyst-like structures and were subjectively more aggressive when compared with extra-osseous canine acanthomatous ameloblastomas. Amyloid-producing odontogenic tumors (n = 3) had subjectively uniform CT imaging characteristics and consisted of round soft tissue and mineral attenuating masses with multiple associated cyst-like structures. Fibromatous epulides of periodontal ligament origin (n = 4) were contrast enhancing extra-osseous masses that were rarely referred for CT examinations and 25% (1/4) were not visible with CT. Other odontogenic tumors were less represented or had more variable CT imaging characteristics. Mass-associated tooth destruction was appreciated more often with dental radiographs and extra-oral tumor extension was identified more often with CT.

“…Odontomas are mixed odontogenic tumours made up of epithelial and mesenchymal dental tissues (Regezi et al 2003a;Sowers and Gengler 2005). These tumours are biologically classified as hamartomas (proliferation of normal tissue with abnormal organisation) instead of neoplasms (Dubielzig et al 1986;Crabill and Schumacher 1998;Regezi et al 2003a).…”

“…Odontomas tend to be reported in younger animals including: equine, canine, feline and human patients Regezi et al 2003a;Brounts et al 2004). They are considered rare in these species and may only contribute 0.05% of biopsy specimens in dogs (Sowers and Gengler 2005). It has been suggested that odontogenic tumours may be more common in horses then other species (Knottenbelt and Kelly 2005).…”

“…Primary oral tumours are usually odontogenic, osteogenic or soft tissue in origin. Odontogenic tumours are usually found to consist of pure epithelial or mixed epithelial and mesenchymal tissues (Regezi et al 2003a;Sowers and Gengler 2005). There are few reports of complex or compound odontomas in the horse, with these being primarily in young animals (Dillehay and Schoeb 1986;Dubielzig et al 1986;Knottenbelt and Kelly 2005).…”

Summary Complex odontomas are rare odontogenic tumours in horses comprised of a combination of mesenchymal and epithelial tissues. Examination, radiographic and histopathological findings in this patient all represent the typical behaviour of a complex odontoma. Oral tumours in horses may have treatment limitations due to tumour size and location. Similar to treatment in other species, surgical enucleation was curative for this type of tumour.
