Dicephalus parapagus conjoined twins discordant for anencephaly: a case report

Abstract

IntroductionCases of conjoined twins occur so rarely that it is important to learn as much as possible from each case.Case presentationWe present a case of 9-hour-old, female, Nigerian dicephalus parapagus conjoined twins discordant for anencephaly diagnosed only after the birth of the twins. The anencephalic twin was stillborn while the normal one died within 9 hours of birth from cardiopulmonary failure.ConclusionMany congenital defects of interest can now be detected before birth. A severe lesion such as that found in our index case, which is incompatible with postnatal life, requires counselling. If detected early enough during a properly monitored antenatal care, it may indicate termination of pregnancy.

Diagnosis of male dicephalus parapagus dibrachıus conjoined twins discordant for anencephaly at early weeks of pregnancy. Case report

“…Diagnosed at early weeks of pregnancy dicephalus parapagus conjoined twin discordant for anencephaly has not been reported in literature (5) . Although we found three dicephalus parapagus conjoined twins discordant for anencephaly in literature, none of these cases was not diagnosed at early pregnancy period (10,11,12,13) . Also, our case was male fetus despite predominance female fetus in literature (14) .…”

Dicephalus dipus tetrabrachius conjoined twins of Zaria: Case report and literature review

“…[8] Although the outcome is influenced by careful planning and organization from all participants, the prognosis is often predetermined by the underlying anatomy which may preclude successful separation. [9][10][11] Besides there may not be sufficient time for adequate planning if an emergency separation becomes expedient, as was in the present case. Although conjoined twins are rare, occurring in approximately 1 per 50,000 to 1 per 100,000; it should be suspected in all monochorionic, monoamniotic twin pregnancies, and careful Sonographic assessment should be performed to identify the presence of shared fatal organs.…”

A parapagus dicephalus tripus tribrachius conjoined twin with a unique morphological pattern: a case report

“…In addition to the unique morphological pattern, the parapagus dicephalus specimen described here showed anencephaly in the left twin. Although not common, two previous case reports described the combination of these congenital anomalies [10,11]. Both cases concerned parapagus dicephalus dipus dibrachius twins.…”

“…The location and extent of the shared viscera varied and depended mostly on the number of extremities, the extent of duplication of the vertebral column, the distance between both vertebral columns, and the width of the perineum [9]. Even though many variations have been described [5,[9][10][11][12][13][14][15], the morphological pattern of the male parapagus dicephalus tripus tribrachius conjoined twin discordant for anencephaly described in this case report is unique with its almost fully duplicated rump skeleton, heart consisting of a monoatrium with two ventricles, duplication of the penis and bladder, and the third foot showing polydactyly and syndactyly.…”
