title: Multiple bilateral pulmonary nodules masquerading as pulmonary metastasis; a case of nodular sarcoidosis.
abstract: Sarcoidosis is a multi-system inflammatory disorder of unknown etiology that is manifested by the presence of non-caseating granulomas. Multiple pulmonary nodules are rare presentations of sarcoidosis. We report a case of nodular sarcoidosis in a young male of Middle-East origin who had initially presented with bilateral painful ankle edema. His chest X-ray showed multiple bilateral pulmonary nodules. A high resolution computed tomography scan of the chest demonstrated multiple pulmonary nodular lesions and also mediastinal and hilar lymphadenopathy. Subsequent biopsies revealed non-necrotizing granuloma with multi-nucleated giant cells indicative of sarcoidosis. An appropriate work-up was done to confirm the true nature of the nodules and facilitate treatment.
