“…Another hypothesis is that craniopagus parasiticus is caused by a lack of blood supply to the second twin brought about by the degeneration of the umbilical cord, thereby halting the development of the fetus [10]. The main difference between a parasitic twin and conjoined twins is that the parasitic twin fails to develop during gestation, while the normal twin develops fully [11]. …”

Craniopagus parasiticus – a parasitic head protruding from temporal area of cranium: a case report

et al. 2016

BackgroundCraniopagus parasiticus is rare with an incidence of approximately four to six cases in 10,000,000 births. In our case, the head of the parasitic twin protruded from the temporal area of the normal twin’s cranium. The parasitic twin had two deformed lower limbs, of which one was rudimentary, and long bones of the bilateral lower limbs and some pelvic bone. Dissection of the mass of the parasitic twin’s body revealed the intestine but no chest organs or abdominal organs. There was a rudimentary labium but no vaginal opening. In resource-limited countries, maternal age or nutritional factors may play a role in craniopagus parasiticus.Case presentationA 38-year-old multigravida (gravida V para IV) woman of Amhara ethnicity was referred from a rural health center to our hospital due to prolonged second stage of labor at 42+1 weeks. On her arrival at our hospital, an obstetrician decided to do a caesarean section because she was unable to deliver vaginally. A live baby girl weighing 4200 g was delivered. The placenta was single and normal. Her Appearance, Pulse, Grimace, Activity, and Respiration scores were 7 and 9 at 1 and 5 minutes, respectively. She appeared to be grossly normal except for the parasitic co-twin attached to her cranium. After a week of extensive counselling and investigation, a successful separation operation was done. Postoperation, she comfortably suckled on the breast and had no neurological deficit. Two weeks after separation she was discharged in a good healthy condition with an arrangement for postnatal follow up.ConclusionsThe causes of craniopagus parasiticus are still unknown due to a rarity of cases and a limited number of studies on it. There have been only nine to ten cases of craniopagus parasiticus, of which only three survived past birth and were documented in the literature. Genetic scientists and researchers continue to investigate this case because they might find explanations for the birth defect, and provide answers to improve the prognosis and the life chances of twins with craniopagus parasiticus.

“…All these case reports have described the neonatal and post-mortem appearances of affected infants. More recently, with the improvement of resolution of real-time ultrasound, the sonographic detection of this abnormality has been made (Strauss et al, 1987;Okazaki et al, 1987;Fontanarosa et al, 1992). In this report, we describe the antenatal diagnosis by ultrasound of the diprosopus abnormality in a twin pregnancy.…”

A case of diprosopus twinning which is rare conjoined twinning is reported prenatally at 22 weeks’ gestation. 2D ultrasound examinations showed duplication of the craniofacial structures with four hemispheres, two cerebella and two thalami. There were three orbits two external ears, two noses, fused adjacent maxilla and two oral cavities with two fused oral opening and two jaws. The woman did not consent to any further investigations and the pregnancy was terminated. The postmortem examination confirmed the diagnosis in a male fetus with a crown-rump length of 155 mm, weighing 450 g. The body appeared normal except for a small poorly formed rudiment of a supernumerary digit next to the thumb of the right hand. The ultrasound examination and postmortem finding of this case is described with a short review of the literature.
