Keep an eye on the lung.

The case of a 42-year-old man, originally seen in the Ophthalmology clinic after his wife noticed his pupil sizes were different, is presented. He had been feeling tired with lack of energy for 6 months, during which time he had lost about 6.4 kg in weight. Then he started to have night sweats and a non-productive cough. His appetite was good. A chest x ray showed right midzone and some left lung opacities. Thoracic high-resolution CT showed patchy consolidation involving both midzones with widespread nodular shadowing. Transbronchial biopsies showed non-caseating epitheloid cell granulomata consistent with sarcoidosis.
