4. Sarcoidosis
The thoracic CT scan shows multiple small lung nodules in both lungs. The nodules touch the pleural surface, and therefore, are not centrilobular nodules as seen in hypersensitivity pneumonitis and some infectious diseases such as endobronchial spread of tuberculosis. The nodules are along the fissures indicating a perilymphatic distribution rather than random nodules. Small random nodules are seen in hematogenous metastases, miliary tuberculosis, miliary fungal infections and Langerhans cell histiocytosis in the early nodular stage. Perilymphatic nodules are seen in lymphatic spread of carcinoma, lymphoma and sarcoidosis. In addition, the thoracic CT shows some thoracic lymphadenopathy. Small perilymphatic nodules and mediastinal lymphadenopathy suggest sarcoidosis in this young African-American man with a brain lesion.
Bronchoscopy with transbronchial biopsy showed noncaseating granulomas as did a biopsy of the brain lesion consistent with sarcoidosis.
