“…Rowe and others (1968) fully investigated the case of a female infant with an omphalocele, two sets of external genitalia, two anal openings and four lower extremities that underwent complete investigation and partial surgical repair. More recently, a case of a dipygus that had six lower extremities, double external male genitalia, a megabladder, three dilated ureters and a polycystic right and a pelvic left kidney was diagnosed by sonography in a 36‐year‐old woman at second pregnancy referred for sonography at 21 weeks of amenorrhoea because of suspected fetal anomalies (La Torre and others 1998).…”

Caudal duplication is a rare type of conjoined twinning. The aim of this case report is to describe a case of caudal duplication in a male crossbreed puppy. The puppy was macroscopically and radiographically examined after death. External features included a supernumerary limb projecting from the perineum, complete lack of tail, anal atresia, double penis and absence of scrotal sacs. Internal examination showed anomalies involving the intestine and the urinary system. At x-ray examination, the supernumerary limb showed features similar to that of the normal right hindlimb but showed absence of fibula and tibia and presence of three metatarsi and phalanges. The authors discuss the pathogenic mechanisms of this condition, infrequently reported in veterinary practice, pointing out the importance of embryonic duplications commonly associated with dystocia.

In utero and postnatal imaging findings of parasitic conjoined twins (ischiopagus parasiticus tetrapus)

Conjoined twins are a rare developmental anomaly with a reported prevalence of 1.47 per 100,000 births. We present an uncommon case of a parasitic ischiopagus tetrapus with a parasitic ischiopagus partial twin joined to the complete fetus at the level of the ischium diagnosed in utero by fetal MRI. The correct prenatal diagnosis led to birth by caesarean section. Prenatal MRI findings are presented and corroborated by postnatal imaging delineating the full extent and associated anomalies of this rare malformation. Differential diagnosis of duplicated lower extremities is discussed.
