Figure 1.9.7 Mandibular Osteomyelitis and Osteonecrosis (Canine) CT
4y M Scottish Terrier with history of suppura­
tive, ulcerative stomatitis. The dog has had
numerous tooth extractions performed previ­
ously. The molars and caudal premolars are
missing. Representative sequential images
acquired at the level of the first maxillary molar
are shown and ordered from rostral to caudal
(a,b). The alveolar processes in the maxilla are
blunted, and the alveolar cavities have filled
with organized bone (a,b: arrowheads). Large
post‐extraction defects remain in the mandible,
accompanied by alveolar bone destruction and
adjacent reactive periosteal production (a,b:
large arrows). A focal gas collection is also
(a) CT, TP (b) CT, TP evident within the right mandibular alveolar
cavity (a: small arrow). The 3D renderings
reveal the full extent of mandibular periodontal
osteolysis and adjacent reactive periosteal
remodeling.
