Nakata M, Miwa Y, Tsuboi M, Uchida K - J. Vet. Med. Sci. (2014)

Bottom Line: Surgical exenteration of the lesions was performed, and the histopathological diagnosis was an intranasal adenocarcinoma.The prognosis has remained good for over 3 years after treatment.This paper is the first to describe the clinical and pathological features of an intranasal tumor in a rabbit.

ABSTRACT
An 8-year-old spayed female Netherland Dwarf rabbit presented with a two-month history of dyspnea and snoring. A computed tomography (CT) scan of the head revealed mass lesions in the right nasal cavity. Surgical exenteration of the lesions was performed, and the histopathological diagnosis was an intranasal adenocarcinoma. On the basis of this diagnosis, radiotherapy was planned and consisted of eight fractions of 6 Gy administered once a week. After the completion of radiation therapy, the soft tissue density in the right nasal cavity, as detected by CT, significantly decreased. The prognosis has remained good for over 3 years after treatment. This paper is the first to describe the clinical and pathological features of an intranasal tumor in a rabbit.

Mentions: An 8-year-old spayed female Netherland Dwarf rabbit, weighing 1.36 kg, presented with dyspneaand snoring that began 2 months earlier. Another private veterinary clinic had administeredantibiotics via a subcutaneous injection and nebulization. The rabbit’s snoring improved, butnot the dyspnea. Three weeks later, discharge from the right nasal cavity was observed duringconsultation, and a sample collected for bacterial culture yielded a negative result. Becauseof the worsening dyspnea, a CT scan was performed under anesthesia for evaluation of the nasalcavity. Images from the CT scan revealed two mass lesions of soft tissue density within theright nasal cavity (Fig. 1Fig. 1.
