Background: Corticosteroid responsive tremor syndrome is an immune-mediated disorder that primarily affects smalldogs aged 1 to 5 years. It is manifested by generalized tremors of high frequency and low amplitude, with involvement ofhead, trunk and limbs. The diagnosis is based on history, clinical signs and laboratory tests to rule out other conditions, aswell as on the response to corticosteroid treatment. The aim of the present study was to report a case of a female dog withcorticosteroid responsive tremor syndrome that began after estrus.Case: A 1-year-old, undetermined dog, weighing 4.9 kg, was attended at the Veterinary Hospital of Uberaba, with generalized tremors that impaired her walking and feeding. The picture had an acute onset, there was no history of intoxication, trauma, but the animal had an organophosphate-based collar. The bitch was not castrated and had been in heat fora month. In the clinical evaluation, it was observed that besides the tremors, the dog had hypermetria and hyperthermia.Suspected adverse reaction to organophosphorus or encephalitis. The collar was removed from the animal. Hemogram,serum biochemistry, analysis and culture of cerebrospinal fluid and test for distemper were performed. The hemogramwas leukopenia due to lymphopenia. No alterations were observed in serum biochemistry CSF culture and the distempertest were negative. The CSF analyte revealed pleocytosis with predominantly lymphocytes, density and glucose increasedslightly. The diagnosis of encephalitis of inflammatory etiology was established. Treatment with prednisone and diazepamwas performed. Clinical signs improved after seven days of therapy. Approximately one and a half years after the initialclinical picture, the animal presented recurrence of the tremors associated with estrus again. The same treatment was instituted and the dog underwent ovariohysterectomy. There was no relapse of the clinical...(AU)
