The lambda sign in gallium‐67 scintigraphy is a useful clue to the early diagnosis of sarcoidosis

摘要

A 40‐year‐old man with bilateral hilar lymphadenopathy in chest X‐ray and the λ‐sign in gallium‐67 scintigraphy was subsequently diagnosed with systemic sarcoidosis according to the findings of bronchoalveolar lavage and histopathological examinations of transbronchial lung biopsies. Identifying the λ‐sign could be a valuable clue to the early diagnosis of sarcoidosis.
