[Diagnosis of subependymal cysts by brain ultrasound].

Objective: The aim of this study was to describe the clinical data and sonographic evolution of subependymal cysts (SEC) and to compare alone SEC versus SEC combined with other brain abnormalities.

Methods: The diagnosis of SEC relied on the discovery of one/several cysts at the outer angle of one/both lateral ventricles detected by routine brain ultrasound tests in the first days of life. During the 1981-2000 period, 66 neonates had evidence of SEC in Port-Royal Department of Neonatal Medicine.

Lenticulostriate echogenic vessels: clinical and sonographic study of 70 neonatal cases.

Background: Neonatal branching echogenic streaks in the basal ganglia or 'lenticulostriate vasculopathy' (LSV) has no clear comprehensive aetiology.

Objective: To provide some clinical evidence, possibly relevant to aetiology, by analysis of a large series.

Materials And Methods: Seventy cases (9 deaths, 3 post mortem) identified between 1981 and 2000 out of 9,138 neonates with routine brain sonograms (578 in a protocol for neonates from HIV+ mothers).
