Abstract

PURPOSE
To investigate clinical characteristics of neonates with lenticulostriate vasculopathy (LSV) and determine the correlation between LSV and clinical characteristics, especially congenital cytomegalovirus (CMV) infection.
METHODS
We retrospectively reviewed the medical records of neonates with LSV, born at Cheil General Hospital between January 2005 and December 2015. LSV was graded into three groups based on the number of the LSV lesions and classified into an isolated and combined group showing LSV with coexistent abnormalities noted on brain sonography. We compared clinical data based on the LSV classification.
RESULTS
Our study included 102 neonates with LSV, which showed an unilateral pattern in 10 and bilateral pattern in 92 neonates. The numbers of neonates studied based on LSV grading were 33, 53, and 16 in grade 1, 2, and 3, respectively. We observed the isolated LSV in 62 and the combined type in 40 neonates. We observed that 93 (91.2%) of the neonates with LSV did not show specific underlying cause for this condition. Congenital CMV infection was detected in 7 neonates, including 0, 5, and 2 neonates belonging to grade 1, 2, and 3, respectively. Among these, 2 neonates showed the isolated, and 5 showed the combined type of LSV. Statistically, congenital CMV infection was more significantly associated with LSV in grade 2 and 3 than in grade 1 (P < 0.05). Additionally, congenital CMV infection was more commonly observed in the combined than in the isolated LSV type showing a marginal association (P=0.07).
CONCLUSION
We observed that LSV was not clinically significant except when associated with CMV infection. We suggest that neonates presenting with a grade 2 or higher of LSV or a combined type of LSV detected via neonatal brain ultrasonography should be evaluated for CMV infection.
