Abstract:
Tanatophoric nanism is a very rare osteochandrodyasplasia, it affects one birth in 4000. It was first described by Marotaux et al in 1967[1]. Its evolution is towards a rapid death at birth. Its antenatal diagnosis is done by imaging which will allow a psychic preparation of the mother and propose an medical interruption of pregnancy. We report the case of a 29-year-old nulliparous woman who during the follow-up of her pregnancy, a routine ultrasound scan in the framework of the antenatal surveillance of her pregnancy carried out at 28 SA allowed to suspect the diagnosis of tanatophoric nanism, in front of very evocative images associating a macrocephaly, a shortened aspect of the limbs, a narrow thorax contrasting with a bloated abdomen. The course of the pregnancy was uneventful with delivery at 37 weeks of age of a male infant weighing 3100 grams who died after 2 days of life.
