Conjoined twins are one of the anomalies accompanying monozygotic monoamniotic pregnancies with a prevalence of 1 in about 100000 pregnancies and 1 in about 1500 twin pregnancies (1 in about 200 monozygotic twin pregnancies). The most common type is thoracopagus. Prenatal diagnosis is bascd on sonography and, more accurately, on magnetic resonance imaging. In this paper, two cases of conjoined pregnancy are reported. The first case had two heads: one of them anencephalus with cleft lip and cleft palate and the other with bilateral cleft lip and cleft palate in addition to spina bifida. They were delivered in 1988 vaginally and both were stillborn. In the second case the twins were fused in abdominal region and were dclivered by cesarean in 2002.
