Persistent large choroid plexus cyst. A case report.
BACKGROUND
Prenatally diagnosed choroid plexus cysts regress or resolve spontaneously during pregnancy. A persistent large choroid plexus cyst with a prenatal diagnosis has not been reported previously.


METHODS
A 28-year-old, healthy primigravida was referred to our department at 32 weeks' gestation for a suspected fetal intracranial anomaly. Ultrasonography revealed a lateral ventricle 13 mm in width. The ventricle was dilated only in the atrium region. The choroid plexus was not distinct from the inner wall of the ventricle and did not fill the atrium of the lateral ventricle. The patient was followed with bi-weekly ultrasonography until delivery, and the left ventricular width increased from 13 to 17 mm. At 38 weeks' gestation the patient delivered a 3,350-g girl. Magnetic resonance imaging showed a 1.7 x 2.5 x 3.0-cm cyst in the left lateral ventricle. Follow-up magnetic resonance imaging scans at 6 and 11 months showed unchanged findings. Clinical and neurologic examinations at 11 months of age showed normal development.


CONCLUSIONS
Although small (< 1 cm), postnatally persistent choroid plexus cysts are clinically insignificant variants of normal; the prognosis of large, persistent cysts (> or = 1 cm) is less clear. Long-term neurologic follow-up is mandatory for these neonates.
