Resumo
Background: Meningoencephalitis in cats is usually related to infectious diseases but may also be caused by the extension of bacterial infections originated in the middle or inner ear. This paper seeks to report on a case of encephalitis due to an infection in the middle/inner ear in a 15-year-old cat. The diagnosis was made through brain CT scan and culture and antibiogram of material collected during a ventral osteotomy of the tympanic bulla and reported grave intravascular haemolysis associated to the treatment with antimicrobial imipenem with cilastatin sodium that has already been described in humans but not in small animals in the researched literature.Case: A 15-year-old, male, castrated, Siamese cat was brought to the Veterinary Clinical Hospital of the UFRGS. The animal presented pyrexia and hyporexia, tested negative in the immunoenzymatic test to detect antigens of the FeLV and antibodies of the FIV. The animal had a history of three episodes of tonic convulsion within two days and otitis that had gone untreated for 10 months prior to the consultation, with apparent spontaneous remission. After blood tests, serum biochemistry profile, abdominal ultrasound scan, chest x-rays and CT scan was requested. It revealed middle and inner otitis in the right ear. It was performed a ventral osteotomy of the right tympanic bulla. Material was collected for culture and antibiogram. It was confirmed that the animal had an inner otitis of bacterial origin by multi-resistant Klebsiella spp. that was sensitive only to antimicrobial imipenem with cilastatin sodium. Fifteen days into the treatment with this antibacterial combination, grave haemolysis was observed, probably associated to the use of the medicine. The patient died on the 17th day of the treatment which was not interrupted as per its owners decision. At necropsy, both in the tympanic bulla and liver were found mucous content and whitish lumps.[...](AU)
