Image Quiz: Chronically pruritic and odoriferous ears in a basset hound (Sponsored by Intervet/Schering-Plough Animal Health)

Mar 02, 2011

A young, adult basset hound presents to you for evaluation of chronic recurrent ear pruritus and a strong “musty” odor. Historically, when the ears are cleaned, the odor and discharge respond well but the ear remains inflamed and recurrence is rapid. Repeated bacterial culture and sensitivity test results have been unremarkable. Upon otoscopic examination, you find a brownish waxy discharge. Which of these diagnostic tests would be most useful initially?

What is your diagnosis?

a. An anaerobic bacterial culture and sensitivity
b. A fungal culture
c. A skin biopsy
d. Cytologic examination of the ear exudate
e. A therapeutic trial of oral itraconazole
