Subclinical Sjögren's syndrome: a significant 67gallium accumulation in the orbits and parotid glands.

An 8-year-old girl with hypergammaglobulinemia showed an abnormal 67gallium accumulation in the orbits and parotid glands. Although she did not have any subjective siccant complaints, reported typical histopathological and sialographic changes suggesting Sjögren's syndrome (SjS) were observed in the salivary glands. Gallium scintigram might be a valuable and non-invasive diagnostic tool in the diagnosis of children with SjS without sicca symptoms.
