Images 1, 2, and 3
Clinical Differential Diagnosis:
Anorectal malformation (low)
A chest film from the first day of life showed some of the congenital anomalies. An ultrasound exam of the abdomen from the next day showed a stool filled rectal pouch, azygous continuation of the inferior vena cava, and normal kidneys.
Imaging Differential Diagnosis:
The ultrasound measurements did not allow a determination between classifying this as a high or low anorectal malformation.
At 9 months of age the patient underwent a posterior sagittal anorectoplasty and division of the rectovaginal fistula.
Anorectal Malformation (Low)
Follow-up and Prognosis:
The patient had an uncomplicated post-operative course.
