Diffuse periventricular calcification and brain atrophy: A case of neonatal central nervous system cytomegalovirus infection

Abstract

TORCH refers to the most common congenitally acquired infections: toxoplasma, rubella, cytomegalovirus, and herpes simplex virus. Neonatal cytomegalovirus infection remains a common cause of congenital infection worldwide with effects ranging from hearing impairment to significant neurological morbidity. We report a case of a term neonate with ventriculomegaly on prenatal ultrasound who presented with low birth weight, small head circumference, hepatosplenomegaly, and purpuric rash on physical exam. Central nervous system cytomegalovirus infection typically shows periventricular calcifications and associated deep white matter damage and ventriculomegaly. Ultrasound, computed tomography, and magnetic resonance imaging have different roles in the diagnosis of congenital central nervous system cytomegalovirus infection. Many imaging features of congenital cytomegalovirus are distinctive, and can spur a diagnostic work-up as well as help provide a prognosis.
