Sarcoidosis is a chronic granulomatous disease and may present with multisystemic involvement. Hepatic involvement is one of the most common extra-pulmonary diseases and was described as 11.5% in cohort studied in ACCESS study. In such cases early diagnosis is the key to early installment of specific therapy. This may not only improve the prognosis but may also salvage the possible system failure. Routine radiological investigation is generally sufficient to make a diagnosis, however, rare case presentations may require further evaluation to assess extent of extra-pulmonary disease involvement. FDG PET/CT demonstrates high grade glucose avidity in active granulomatous lesions and hence can be used for this purpose. Additionally, it also enables determination of treatment response. In this case report we describe a relapse case of pulmonary sarcoidosis, diagnosed to have liver and spleen involvement on FDG PET/CT scan which was confirmed on histopathology.
