The authors review the color Doppler ultrasonographic (US) features of appendicitis and other diseases that can manifest with acute lower abdominal pain. Causes of acute abdominal pain, other than appendicitis, include gynecologic abnormalities (ovarian cyst, ovarian torsion, pelvic inflammatory disease), gastrointestinal abnormalities (infectious enteritis, Crohn disease, mesenteric lymphadenitis, intussusception), and urinary tract diseases. On color Doppler images, inflammatory and infectious processes usually show locally increased blood flow, whereas cysts and twisted masses have absent blood flow. Enlarged lymph nodes also are avascular. Color Doppler US is a useful adjunct to gray-scale US in evaluating acute lower abdominal pain in children and can aid in defining and clarifying gray-scale abnormalities.
