A 15-year-old girl presented with non-progressive sensorineural hearing impairment in her right ear since her early childhood. She had normal intellectual development. When she was 15 years old, small deep white matter lesions around the lateral ventricles were incidentally detected in brain MRI studies through further investigation of auditory organs. Laboratory data including cerebrospinal fluid analysis and antibodies to aquaporin-4 or myelin-oligodendrocyte glycoprotein were normal. She was diagnosed as a congenital cytomegalovirus (CMV) infection based on the detection of CMV DNA from preserved umbilical cord tissue by real-time polymerase chain reaction. It should be kept in mind that a case of congenital CMV infection with normal intelligence may be underdiagnosed and that sensorineural hearing impairment from early childhood and deep white matter abnormalities can be key features giving rise to suspicion on congenital CMV infection.
