Choroid plexus cysts: A normal finding on ultrasound

Abstract

Within a period of 2.5 years, cystic structures in the choroid plexus were encountered at cerebral sonography in 70 neonates and babies (45 male, 25 female; 18 premature babies). Their prevalence in patients examined during the first 4 weeks of life (n = 55) was 3%. The size of the cysts ranged from 1-4 and, rarely, up to 7 mm. They were mostly solitary and unilateral. Follow-up sonograms over periods up to 13 months showed that most of the cysts persisted unchanged. A few disappeared (n = 7), while distinct increase in size was observed in 1 case. Since no additional sonographic changes were observed and none of the patients displayed any neurological abnormalities and no association existed with any other, particularly chromosomal, disease, such plexus cysts are postulated to represent a normal sonographic finding and do not require follow-up.

Cranial ultrasound findings in well newborn Ugandan infants

“…There is an association with chromosomal abnormalities such as trisomy 18 if the cysts are greater than 1 cm, bilateral and if other structural abnormalities are present,33 and some reports associate CPC with cytomegalovirus 24. The largest study of CPC seen on postnatal cUS in 70 preterm and term infants (age range 1 day to 1 year) reported an incidence of 3%;34 in our cohort 19.6% had CPC of which 10% were isolated, the remaining cases had abnormal tissue echogenicities but not structural abnormalities.…”

“…The largest report of choroid plexus cysts on postnatal sonography was done by Riebel et al 3 They reported on 70 neonates. The cysts were usually situated in the dorsal part of the choroid plexus.…”

Choroid Plexus Papilloma and Cysts in the Aicardi Syndrome: Case Reports

“…The features of benign, choroid plexus cysts which dis tinguish them from pathological cysts such as those found in Aicardi syndrome are their confinement to the glomus [14], smaller size-usually 1-4 mm in size and rarely up to 7 mm [15]-and usual stability in size or complete disap pearance over time [ 15].…”
