Abstract
A 5-month-old male Russian Blue cat with a chief complaint of dysuria similar to urethral atresia, along with difficulty in standing on both hind limbs in several days, was referred to a primary veterinarian. Inflammation of the lower urinary tract was suspected and treatment was started. A neurological examination revealed a mild head tremor and upper motor neuron paresis of the hind limbs. Magnetic resonance imaging showed abnormal signal intensities around the ventricles, the brain meninges to the lumbar spine, and spinal parenchyma. Based on these findings, the antibody test results, and results from feline coronavirus (FCoV) genetic tests using serum and cerebrospinal fluid, a central nervous system-type of feline infectious peritonitis/type I FCoV was strongly suspected. Urethral atresia is a condition frequently encountered in male cats. For juveniles, there is a need to distinguish this condition from a neurological disease caused by a FCoV infection, and a prudent explanation to the owner is important.
