Calcifications in islet cell tumors of the pancreas are rarely seen radiologically. We are reporting a case of an insulinoma with "sunburst" type calcification that has been previously described as specific for cystadenoma or cystadenocarcinoma of the pancreas.
A volvulus of the transverse colon in a 78-year-old woman is reported. The diagnosis is established by abdominal film and barium enema with surgical confirmation. Women are more commonly affected than men. There is a higher mortality rate for volvulus of the transverse colon than for either sigmoid or cecal volvulus.

In the pediatric patient, the presence of a right aortic arch is an important roentgen observation. It may be associated with vascular rings and cyanotic heart disease and may complicate the repair of tracheoesophageal fistula. It may be missed on conventional low KVP radiographs but is easily detected on high kilovoltage-filtered films with air gap magnification.
Potter renal nonfunctional syndrome is an association of facial and limb anomalies, pulmonary hypoplasia, and fetal renal anomalies which lead to marked oligohydramnios, including renal agenesis (true Potter syndrome), renal cystic dysplasia, and obstructive uropathies. Some infants survive long enough to develop severe respiratory distress secondary to pulmonary hypoplasia. The underlying renal disease is often noted only at autopsy. We studied four infants, only one of whom had clinical signs of the renal nonfunction syndrome. Portable voiding cystourethrography revealed a tiny bladder in three infants with cystic dysplasia kidneys (two of these infants had reflux into unused ureters). Bladder hypertrophy and vesicoureteral reflux secondary to posterior uretral valves were noted in the fourth infant.
Five cases of slipped femoral capital epiphysis were noted in children with prior irradiation for malignancy whose femoral head and neck had been included in the radiation portal. Three of the 5 were patients who had lymphoma. As a result of increasing survival rates for these types of patients, this previously unrecognized radiation-related growth disturbance may be more likely to be seen in the future.
