Focal Dorsal Enhancement of the Tympanic Bulla: An Early Indicator in Feline Otitis Media.

ABSTRACT: Evaluating the morphological changes of the tympanic bulla and the contrast enhancement (CE) patterns are key factors in diagnosing otitis media and predicting its underlying etiology. However, limited research exists on the CE patterns of the tympanic bulla in cats with bulla effusion. This retrospective study aimed to investigate the prevalence and patterns of CE in the tympanic bulla based on the presence and severity of bulla effusion in cats. Feline head CT or brain MRI images from six institutions were analyzed. Transverse pre- and postcontrast CT and MRI images were reviewed to assess the presence and severity of bulla effusion, along with the presence, pattern, and location of tympanic bulla CE. A total of 644 tympanic bullae from 322 cats were included. Bulla effusion was detected
