Abstract

A 38-year-old woman with twin pregnancy was referred after detection of hydrocephalus in one fetus at 23+1 weeks' gestation. Sonography showed hydrocephalus, a scalloping of the frontal bone giving a lemon-like configuration, and meningocele. The affected twin was terminated by ultrasonographically guided intracardiac injection of 4 ml (8 mEq/L) potassium chloride solution at 24+5 weeks' gestation. Chromosomal analysis of the other fetus showed normal findings (46, XX). Serial ultrasound scans and coagulopathy tests were unremarkable. Preterm premature rupture of the membrane was developed at 33+3 weeks' gestation, and emergency Cesarian section was done. A healthy 1360 g female was born, with Apgar scores of 7 and 8 at one and five minutes, respectively.
