title: X-ray computed tomography-aided diagnosis of nasal adenocarcinoma, with extension to the skull and central nervous system, in a dog.
abstract: A dog with tonoclonic seizures, disorientation, and tetraparesis was evaluated by use of skull radiography. An advanced, highly aggressive process was centered within the caudal portion of the right nasal cavity. X-ray computed tomography further defined the mass to be occupying the caudal portion of the nasal cavity and frontal sinuses, with concurrent involvement of the adjacent turbinates and frontal, maxillary, and palatine bones. Despite the aggressive nature of the process, no alteration to the external contour of the cranium or nose was observed. Histologic examination revealed well-differentiated adenocarcinoma.
