Abstract
Patient was a 6-year-old boy, who was admitted to our hospital with fever persisting for more than 2 weeks.
After admission, he had no clinical symptoms other than the fever. On the 24th day after the onset of fever, the
patient developed bladder and bowel dysfunction and gait disturbance. Cerebrospinal fluid analysis showed
pleocytosis, and the IgG index was elevated. From his clinical and laboratory findings, he was diagnosed with
transverse myelitis. Two courses of methyl-prednisolone pulse therapy were administered. After treatment, his
symptoms improved without neurological sequelae. Autoimmune neuropathy usually progresses rapidly, but our
case shows that it can sometimes progress subacutely. Transverse myelitis should be considered as one of the
causes for prolonged fever.
