“…The advantages of CT include its ability to visualise the entire dentition, its surrounding structures such as periodontal tissues and alveolar bone, and soft and hard tissues associated with mastication (Van Caelenberg and others 2011). CT also allows for assessment of the head without superimposition and it takes less time than that required for positioning the animal for full-mouth dental radiographs (Chesney 1998, Crossley and others 1998, Brenner and others 2005, Capello and Cauduro 2008, Mackey and others 2008). …”

The role of computed tomography in the assessment of dental disease in 66 guinea pigs

Sixty-six guinea pigs with dental disease were presented to the University of Veterinary Medicine, Vienna, Austria, from 2006 to 2010. Almost all patients had a history of eating difficulties (95 per cent) and underwent clinical and oral examination as well as CT of the head. Findings on extra- and intraoral examination were asymmetric elongation (n=28) and symmetric bridging (n=24) of cheek teeth, obliquely worn incisors (n=17), palpable lower jaw swellings (n=13), exophthalmos (n=10) and incisor macrodontia (n=6). Eighty per cent of guinea pigs with exophthalmos showed ipsilateral periapical disease of the maxillary cheek teeth on CT. Ninety-two per cent of patients with palpable lower jaw swellings showed corresponding dental pathologies on CT. Periapical disease of incisors (n=11) and cheek teeth (n=32) were the most common findings on CT. All abnormally large incisors were found on oral examination and CT, but macrodontia of cheek teeth could only be visualised by CT. Deviation of the lower jaw evaluated in awake animals by visual inspection appeared to correlate with cheek teeth abnormalities. Results emphasise the importance of diagnostic imaging, in particular CT, in guinea pigs with dental disease in order to localise lesions and underlying aetiologies.

“…Sedation or general anaesthesia is essential for proper positioning and for reducing breathing artefact. Because of the inability of standard radiography to demonstrate areas of bone loss and osteomyelitis due to superimposition of other bony and soft tissue structures and the superior contrast resolution with spiral CT scanners, CT of the head is extremely useful as an adjunct to traditional radiography and to determine margins and extent of tumour growth [14] [20]. In the present report, blood haematology and biochemistry were performed to rule out concurrent disease.…”

This report describes the clinical manifestations and pathological findings in a 4-year-old neutered male dwarf rabbit diagnosed with a mandibular fibrosarcoma. The rabbit was evaluated for a unilateral mandibular swelling and an acute onset of oral blood loss. Physical examination confirmed a marked facial asymmetry with a swollen painful left mandible. Radiographic projections of the skull revealed a left mandibular mass extending into the oral cavity. Tissue biopsies demonstrated severe bone destruction and a presumptive pathological diagnosis of a mandibular osteosarcoma were made. A helical CT (computed tomography) study of the skull confirmed the severe mandibular bone destruction and the oral extension of the mass. The patient was treated palliative with oral meloxicam and subcutaneous penicillin injections. Six months later, the rabbit died in a natural way. Postmortem examination led to final diagnosis of severe left facial malformation due to mandibular fibrosarcoma. A bile duct adenoma was found in the liver. To the author's knowledge, this is the first description of a spontaneous mandibular fibrosarcoma in a pet rabbit.

“…Radiographic findings in healthy and unhealthy rabbits have been described by numerous authors (Okuda and others 2007, Gracis 2008, Capello and Cadouro 2008, Boehmer and Crossley 2009, Van Caelenberg and others 2011). Korn and others have added to these findings by studying skull radiographs of fully grown offspring and adult breeding rabbits to find a relationship between reference lines previously described (de Abreu and others 2006, Boehmer and Crossley 2009) and clinical findings.…”
