Computed tomography is known to have a high sensitivity in the detection of lung abnormalities caused by cytomegalovirus (CMV) infection. Gallium-67 scintigraphy has long been used in nuclear medicine to evaluate many different infectious processes. A gallium-67 scan was performed to search for the source of the intermittent fever of 2 months’ duration in an 18-year-old immunocompromised man. The gallium-67 images showed diffuse abnormal activity in both lungs while a chest computed tomography was negative. On the basis of gallium scan result and subsequent laboratory results, a diagnosis of CMV pneumonitis was made. The patient received anti-CMV therapy and recovered promptly.
