Radiologic spectrum of opportunistic infections of the upper gastrointestinal tract

Clinical findings and barium studies were reviewed in 34 patients with upper gastrointestinal opportunistic infections, including two with gastric involvement. The spectrum of radiologic features is presented with particular attention to early subtle findings such as disturbance of esophageal motility and tiny marginal filling defects. While most cases are due to Candida albicans, other organisms may also invade the upper gastrointestinal tract in the debilitated host.
