We report a case of cephalothoracopagus janiceps monosymmetros that was diagnosed prenatally by ultrasound at 23 weeks' gestation. Obstetric ultrasound demonstrated conjoined female twins with a single fused cranial vault irregular in contour, duplicated cerebra, one face, two eyeballs, a fused thorax, two hearts, two thoracic spines, eight limbs, and polyhydramnios. The pregnancy was terminated and all the features described prenatally were observed at necropsy. The asymmetrical fused faces consisted of a ventral humanoid face with micrognathia, microphthalmia, low‐set ears, a normal nose, and an opposite reduced face with partial facial features of a central narrowed fissure and paired synotic ears. The conjoined twins had fused umbilical cords, omphalocoele, and a single oesophagus, stomach, and duodenum, but duplicated pancreases, spleens, and central nervous, cardiopulmonary, hepatic, and genito‐urinary systems. The common gastrointestinal tract bifurcated at the level of the jejunum. Our case documents a very uncommon variety of asymmetrical cephalothoracopagus janiceps with duplicated central nervous systems. © 1997 by John Wiley & Sons, Ltd.
