CT of the head, thorax and abdomen –
Head: Both tympanic bullae are completely filled with homogeneous soft tissue attenuating material without contrast enhancement. The osseous wall of the tympanic bullae is bilaterally mildly thickened and slightly irregular and porous on the right side. Mild thickening and increased contrast enhancement of the luminal mucosal lining is noted bilaterally.
The retrobulbar spaces are unremarkable.
Thorax: The ventral aspects of the right middle and the caudal compartment of the left cranial lung lobe show a very mild ground-glass opacity and mildly reduced volume.
Cystic lesion papillary process of the liver; block vertebra L1/L2.
A retrobulbar mass was not identified and there is also no evidence of exophthalmus.
No structural changes associated with the previously diagnosed gastrointestinal lymphoma were noted.
The findings of both tympanic bullae are typical for subclinic chronic otitis media which is common in feline patients. A possible cause for this could be a subclinical rhinal disease like cat flu. However there is no macromorphologic evidence of relevant rhinitis at this point.
