COMPUTED TOMOGRAPHY AND MAGNETIC RESONANCE IMAGING OF A RHINOSINUSITIS SECONDARY TO A DENTAL ABSCESS IN A CRESTED PORCUPINE (Hystrix cristata)

Abstract

A captive crested porcupine (Hystrix cristata) adult male was imaged due to reduced food intake, anorexia, fever, nasal discharge, changes in fecal quantity and size, and respiratory difficulties. Advanced imaging diagnostic techniques such as computed tomography and magnetic resonance imaging were performed to evaluate the animal. These techniques were very helpful to delineate the dental abscess, as well as the extension of the process to other locations such as the nasal cavity and the tympanic bulla. This is the first description of rhinosinusitis secondary to a dental abscess in a crested porcupine. UPORABA RAČUNALNIŠKE TOMOGRAFIJE IN MAGNETNE RESONANCE ZA SLIKANJE RINOSINUZITISA, NASTALEGA ZARADI ZOBNEGA ABSCESA PRI AFRIŠKEM JEŽEVCU (Hystrix cristata) Izvleček: Odraslega samca afriškega ježevca (Hystrix cristata) v ujetništvu smo slikali zaradi zmanjšanega vnosa hrane, anoreksije, nosnega izcedka, sprememb v količini in velikosti iztrebkov ter težav z dihanjem. Uporabili smo napredne tehnike slikovne diagnostike, kot sta računalniška tomografija in magnetna resonanca. Te tehnike so bile zelo koristne pri opredelitvi zobnega abscesa in razširitve procesa na druga mesta, kot sta nosna votlina in timpanični del temporalne kosti. To je prvi opis rinosinuzitisa, ki je posledica zobnega abscesa pri afriškem ježevcu. Ključne besede: ježevec; zobni absces; računalniška tomografija; magnetna resonanca
