Vaskulopatia lenticulostriata u noworodków : opis przypadków

Background: Lenticulostriate vasculopathy (LSV) is sometimes detected as stripe-like vascular echogenicities in the region of the basal ganglia on routine brain ultrasonography in neonates. LSV is often associated with various perinatal and neonatal abnormalities. Case report: Eight infants had echogenic stripes in the basal ganglia at the location of the lenticulostriate arteries, seen by head ultrasound. One patient had infection with rubella, three had respiratory disease, one with twin to twin transfusion, two with congenital malformation, and one had a restrictive ductus arteriosus in prenatal diagnosis. Brain computed tomography in one sonographically diagnosed LSV case failed to display the lesion. Sonographic follow up of patients with LSV showed progression in one case, no change in six, and resolution of lesions in one case. Conclusions: Sonography is helpful in detecting early noncalcific inflammation and mineralisation in vasculitis. LSV has varied clinical associations. Although nonspecific, these findings should alert the physician to the possibility of congenital infection, chromosomal abnormality, or prenatal drug exposure.
