Strophosomia is a severe form of congenital ventral fissure, all abdominal and thoracic viscera being free in the uterus.
It is an extreme case of celosomia.
In humans
It is a very rare dysmorphic feature in humans.[1]
In farm animals
The condition occurs regularly in calves and lambs. The spine is flexed 180° so that the caudal region is near the neck, in so-called Schizosoma reflexum.[2]

Cesarian section is often required in cows. Fetotomy can resolve the condition in ewes.
