Ultrasound is effective for differentiation of perforated from nonperforated appendicitis in children.

In young patients with sickle cell trait, an infiltrative renal mass with associated retroperitoneal adenopathy and caliectasis are characteristic findings of renal medullary carcinoma on CT and MRI.

A spectrum of findings in gastric volvulus exists. Mesenteroaxial volvulus has greater morbidity and mortality. Radiographic findings of spherical gastric dilatation, paucity of distal gas and diaphragmatic elevation are suggestive of acute volvulus, particularly in patients with predisposing factors.
