Cytomegalovirus pneumonia in a 27-year-old man who underwent kidney transplantation. High-resolution (1.0-mm collimation) CT scan obtained at level of distal trachea 32 days after transplantation shows bilateral patchy areas of ground-glass opacity with crazy paving appearance. The presence of a few poorly-defined centrilobular nodules (arrows) and bilateral pleural effusion should also be noted.
