Encephalitozoonosis was clinically suspected in a rabbit with an acute head tilt. Treatment with febantel, corticosteroids, and antibiotics had been continued for 27 days, at the end of which the clinical signs disappeared. The rabbit had remained in a good physical condition for another 59 days and was then euthanatized for the purposes of a pathological examination. Histopathologically, mild gliosis and perivascular cuffs of mononuclear cells were found in the lateral vestibular nuclei of the medulla oblongata. Multifocal lesions of non-suppurative granulomatous inflammation were observed in the cerebral cortex and kidney. Based on these findings, a diagnosis of encephalitozoonosis was confirmed, and it was suggested that the head tilt seen in the rabbit might be related to the lesion in the medulla oblongata.
