Antenatal sonographic features of intestinal neuronal dysplasia type A associated with polydactyly and micromelia

Abstract

Type A intestinal neuronal dysplasia is a congenital abnormality that is a very rare disease. Here, we report on a patient who had intestinal dilatation with serial changes and polydactyly, as shown on prenatal ultrasound. Bowel obstruction symptoms were shown at 16 days of life. An open abdominal surgery was performed. Malrotation of the bowel and narrowing of the area from 15 cm above the ileocecal valve were noted. Therefore, a right hemicolectomy, including lesions was performed. The patient was diagnosed with type A intestinal neuronal dysplasia by pathology.
