Unusual radiological appearances associated with hypertrophy of the urinary bladder simulating haemangioma in a newborn infant

The purpose of this paper is to draw attention to an unusual cystographic appearance of the bladder in a newborn infant and to relate this to the pathological findings. A female infant, birth weight 9 lb. 6 oz., was admitted under the care of Mr. J. E. Scott with possible intestinal obstruction, when one day old. There was an abdominal mass arising from the pelvis which proved to be an enormously enlarged and distended urinary bladder. A radiograph of the abdomen at that time (Fig. 1) showed the grossly distended bladder extending up into the epigastrium and displacing the stomach, small bowel and transverse colon upwards and to the left. Catheterisation yielded 400 ml. of urine. Intravenous pyelography showed a marked degree of bilateral hydronephrosis with tortuous dilated ureters.
