Case Studies
8 Year Old Lab Mix Not Eating, Drooling, Droopy Left Eye and Painful Ea
Overview
Signalment and History
8 yr old, MN, Lab Mix, presented to rDVM for not eating, drooling from left, and had droopy left eye. Slight left temporal and masseter muscle atrophy noticed. Painful base of left ear, inflamed canal, eardrum not visualized. Normal skull radiographs. Skull CT was requested for further evaluation.
Diagnostics Prior to CT Scan
- Pre-Op lab work revealed slight monocytosis, otherwise unremarkable.
High Definition CT Scan
Patient was anesthetized and a pre contrast CT scan of the skull was performed. Subsequently, Omnipaque ™ (contrast agent) was administered IV and a post contrast study of the skull was acquired.
Findings of Skull CT
Severe left otitis media, bilateral chronic otitis externa and left medial retropharyngeal lymphadenopathy. All changes are likely secondary to chronic inflammation and infection with aural cholesteatoma formation. A neoplastic process is less likely but possible. These findings explain the facial nerve abnormalities.
