“…10 On the other hand, amniotic band sequence contains a wide spectrum of deformities ranging from minor limb and digital defects to life-threatening anomalies, such as neural tube defects and LBWC. 1 Our case can be considered as a part of this spectrum considering some defects, such as involving lower extremities, scoliosis and facial cleft. Despite the similarity of the etiopathogenesis and structural anomalies, we can conclude that our case is not LBWC, because of the absence of thoracoabdominal defects or spina bifida.…”

“…Amniotic band syndrome (ABS) is a heterogeneous congenital defect characterized by limb abnormalities, craniofacial and body wall deformities. 1 Although there are various theories explaining the cause of ABS, the exact reason is not clearly understood. The diagnosis is usually made during obstetric ultrasound (US) examination before the 20th weeks of gestation.…”

Amniotic band syndrome can lead to a wide spectrum of congenital abnormalities including orofacial and visceral defects. It is associated with malformations in truncal, craniofacial regions and the limbs, whereas it sometimes may imitate some genetic disorders. Here, we present an atypical case mimicking amniotic band syndrome with a facio‐upper arm band that was having multiple fetal structural abnormalities including scoliosis, bilateral cleft lip and palate, upper limb abnormality, unilateral anophthalmia with contralateral microphthalmia, left hypertrophic kidney and severe ventriculomegaly.

“…It is thought that the most severe defects (ie, craniofacial and visceral) result from amnion rupture within the first 45 days of life (71). Craniofacial abnormalities include atypical encephalocele and facial cleft, and limb defects range from constriction bands to amputation; both abdominoschisis and thoracoschisis have been described (72).…”

Abdominal wall defects are a complex group of anomalies, and many are incorrectly diagnosed. Evaluation of the defect relative to the umbilical cord insertion site is fundamentally important in differentiating among the various malformations. The two most common abdominal wall defects are gastroschisis, in which the defect is on the right side of the normally inserting cord and free-floating bowel loops are present, and omphalocele, in which the cord inserts on a membrane-covered midline defect. Omphalocele may also form a portion of a more complex defect that may remain undiagnosed without thorough evaluation. In cloacal exstrophy, the defect extends inferiorly and the bowel loops extrude between the two bladder halves. In pentalogy of Cantrell, the defect extends superiorly and is typically associated with ectopia cordis. Bladder exstrophy is a lower abdominal defect in which the hallmark finding is absence of a fluid-filled bladder. The cord insertion site is normal to low but does not form part of the defect. Both body stalk anomaly and abdominoschisis due to amniotic bands cause severe malformations, often involving extrusion of solid organs and the bowel. Although these two entities have many overlapping features, body stalk anomaly may be recognized on the basis of absence of a free-floating umbilical cord. With use of an algorithmic approach beginning with discovery of the location of the defect, a more precise diagnosis can be determined that may directly affect pre- and postnatal management decisions.

A boy born to healthy, young, nonconsanguineous, white parents was born at 40 weeks of gestation by vaginal delivery after an uneventful pregnancy to a gravida I mother. The Apgar score was 9 and 10 at 1 and 5 min, respectively. Anthropometric parameters including birth weight (3480 g), length (52 cm), and head circumference (35.5 cm) were all normal (25th-50th centiles). On physical examination, the baby presented a constriction ring of the left arm, hypoplastic left upper limb (Fig. 1a), wrist, and fingers of the left hand in contracture (Fig. 1b), a skin-covered mass extending asymmetrically into the buttock, and a 7 cm caudal appendage of a soft, boneless, well-circumscribed tissue located at the sacrococcygeal region (Fig. 1c). Ultrasonography and MRI indicated a closed spinal dysraphism with nonossified posterior elements of superior sacral vertebrae and a lipomyelocele. The spinal cord was tethered at the level of L4-L5 tracted by the large lipoma, whereas fatty tissue was projecting out of the spinal canal inside the caudal appendage (Fig. 2). Liver microcalcifications and a bilateral grade I hydronephrosis were also observed on abdominal ultrasound. On ophthalmic examination, the retinal epithelium was hypopigmented, whereas the optic nerves and the fovea were intact. Heart anatomy and function were normal.The affected left upper limb was treated by multiple Z-plasty combined with removal of fibrous groove and fasciotomy. Neurosurgical excision of the caudal appendage was also performed. On last examination, at the age Fig. 1Left arm (a) and hand deformities (b) and the caudal appendage (c).
