BACKGROUND Complete non-mosaic trisomy 22 is a fatal chromosomal disorder that only few fetuses can survive over 12 weeks as reported. Prenatal sonographic findings combined with postnatal or postmortem discoveries showed characteristic multi-systematic anomalies. METHODS The unborn baby of a 35-year-old pregnant woman was found to have several anomalies during a prenatal sonographic scan, including intrauterine growth retardation, ventricular septal defect, flat facial profile, and unclear bilateral kidney structures. METHODS The fetus was diagnosed as having complete non-mosaic trisomy 22 by chromosomal analysis. METHODS The pregnancy was terminated at 24 weeks, and autopsy was permitted. RESULTS Postmortem examinations revealed additional long-sectional spina bifida occulta and imperforate anus. CONCLUSIONS This was the first time a case of spinal cord defect was reported in trisomy 22 fetuses. More attention should be paid to the spinal cord during sonographic examinations in trisomy 22 fetuses.

D001006 Anus, Imperforate A congenital abnormality characterized by the persistence of the anal membrane, resulting in a thin membrane covering the normal ANAL CANAL. Imperforation is not always complete and is treated by surgery in infancy. This defect is often associated with NEURAL TUBE DEFECTS; MENTAL RETARDATION; and DOWN SYNDROME.

D016136 Spina Bifida Occulta A common congenital midline defect of fusion of the vertebral arch without protrusion of the spinal cord or meninges. The lesion is also covered by skin. L5 and S1 are the most common vertebrae involved. The condition may be associated with an overlying area of hyperpigmented skin, a dermal sinus, or an abnormal patch of hair. The majority of individuals with this malformation are asymptomatic although there is an increased incidence of tethered cord syndrome and lumbar SPONDYLOSIS.
