Gallium scanning in children with fever of unknown origin.
Scintigraphy with Gallium 67 is frequently used in the evaluation of children with fever of unknown origin (FUO). Its usefulness in this setting, however, has not been definitely established. We reviewed the clinical records and imaging studies of 30 children with FUO who had Gallium scans. We defined FUO as a febrile illness of greater than two weeks duration which remained undiagnosed after initial clinical, laboratory and radiographic evaluation. 4 of 30 children had positive Gallium scans. Of 25 children with only systemic signs and symptoms in addition to fever, 1 had a positive scan. Of 5 children with more focal complaints, 3 had positive studies: all had localized infections which had remained occult despite imaging with other modalities. We conclude that in most children with FUO, who have only systemic complaints, Gallium scanning is rarely useful. It may be very helpful, however, when there is a suspicion of localized infection, even if other imaging studies are negative.
