Background In 2013, Utah enacted legislation requiring that infants failing newborn hearing screening be tested for cytomegalovirus infection. As a result, cytomegalovirus-infected infants are being identified because of hearing deficits. The neuroimaging findings in this population have not been characterized. Methods Retrospective medical record review was used to identify patients seen at the University of Utah and Primary Children’s Hospitals in Salt Lake City, Utah, who failed newborn hearing screening. A cohort of patients with congenital cytomegalovirus infection, brain magnetic resonance imaging (MRI), and sedated auditory brainstem response testing was studied. Results Seventeen patients were identified; 11 (65%) were female. Confirmatory auditory brainstem response testing, performed at a median age 29 days, showed profound hearing loss in 8 (47%) subjects, severe loss in two (12%), moderate loss in two (12%), and mild loss in three (18%); two (12%) subjects had normal hearing. The diagnosis of cytomegalovirus infection was made at a median age 23 days. Brain imaging was performed at a median age 65 days. Ten (59%) subjects had one or more neuroimaging abnormality. White matter lesions were found in eight (47%) subjects, cysts in three (18%), and stroke in two (12%). Polymicrogyria was identified in two (12%) subjects. Seven (41%) subjects had normal brain MRIs. Conclusions These results indicate that most infants whose cytomegalovirus infections were identified after failing newborn hearing screening had abnormal brain MRIs. Our results suggest that brain MRIs should be considered in infants with congenital cytomegalovirus infections who are identified through hearing screening programs.
