Ischiopagus parasitic twin: A rare case report

Abstract

Parasitic conjoined twinning is a rare clinical entity with a reported incidence of only 1/1 million births. The most common site of attachment of the parasite is epigastrium. The parasitic attachment at ischium is among the least common subtypes. Here, we report a case of ischiopagus parasitic twin with a favorable outcome. The host twin had no major anomaly, and the twins did not share any organ. Surgical separation of parasitic twin and primary closure of the defect of autosite was done without challenges. The aim of this communication is to add to the literature another rare case of parasitic twinning and to highlight the fact that ischiopagus parasitic twinning although, rare, has a good prognosis in the absence of associated anomalies.
