ABSTRACT
INTRODUCTION:
Intrauterine infection due to cytomegalovirus is the most common of the intrauterine viral/parasitic infections that affect the central nervous system and cause permanent lesions in the cortex as well as the subcortical white matter. Studies using brain magnetic resonance imaging (MRI) are limited. MATERIAL ANDMETHODS:
Six patients (4 females and 2 males) were studied in the first months of life in order to make a diagnosis of congenital cytomegalovirus, and identify the cortical and subcortical lesions using the necessary MRI sequences.RESULTS:
The six patients showed malformations of cortical development (MDC) (schizencephaly, polymicrogyria or lissencephaly-pachygyria) from the neonatal period, and diffuse changes of the white matter, which remained with few changes during the first two years. They then began reducing in size in the form of high signal areas in T2, restricted to certain areas, and were evident for a few years more with little change.CONCLUSION:
Intrauterine infection due to cytomegalovirus causes changes in the cortical grey matter, which consists of MDC, and in the subcortical white matter. The latter show a changing aspect as they appear as diffuse and wide areas of high signal intensity, which is usually due to delay in myelinisation, but could also be caused directly by the cytomegalovirus. These changes in the white matter are subjected to morphological changes throughout the first years of life, leading to brain atrophy. The neurological sequelae of these lesions left by these alterations are severe and chronic.
