上腹部非对称性联体双胞胎的罕见病例

摘要

Asymmetrical conjoined twins or heteropagus twins are extremely rare. They ar e characterized by an incomplete component (parasite) that is normally smaller a nd dependent on the host (autosite). In cases of an epigastric heteropagus twin, the insertion occurs in the epigastrium. There are few reports of epigastric he teropagus twinning in the English- language literature. The authors report an e xtremely rare case of epigastric heteropagus twinning in which the parasite pres ented with head, thorax, and a rudimentary heart.
