This is a 32-year-old woman, G5 P4 (4 previous normal pregnancies). She is referred for hydrocephalus at 33 weeks of pregnancy. The findings are:
* severe hydrocephalus,
* images suggestive of encephalocele (artery seen on color Doppler, 3-D rendering)
* low-set ears,Â
* normal calcification of calvarium,
* frontal bossing,
* depressed nasal bridge,
* exophtalmos,
* short ribs, narrow thorax,
* severe rhizo-micromelia of limbs,
* bowed bones
* polyhydramnios,
* normal cardiac 4-chamber view and normal outflow tracts,
This represents thanatophoric displasia type II. What might appear as a encephalocele is simply the clover-leaf shape skull.
