A case of a male baby with a tail is described. The tail was surgically removed. Histopathological investigation showed that it was covered with hairless skin. It contained adipose and fibrous tissue, arteries, veins and nerves, but no cartilage, bone or muscle. In most cases of these caudal appendages surgical excision is sufficient, although an underlying anomaly should be excluded radiographically.
In 1991 33 perinatal deaths occurred at Rogaland hospital. Seven of the babies showed severely retarded growth (< 3 percentile) compared with the delivery date indicated by ultrasound. Five babies showed moderately retarded growth (from 3-10 percentile) and the remaining babies were not definitely growth retarded. For the three groups the delivery date indicated by ultrasound was on average 18, eight and five days later than the date estimated according to the rule of Naegele. A delivery date estimated by ultrasound at 18-19 weeks may cause serious misjudgements in cases of early retardation of growth. Earlier ultrasound examination is recommended for a more reliable estimated date of delivery. The author discusses ultrasound examination which differentiates estimation of delivery date and screening for malformation.
