[Secondary syphilis with pulmonary involvement: report of a case with emphasis to the high-resolution CT and magnetic resonance findings].

A 37-year-old man presented with thoracic pain and fever. The physical examination showed reddish skin lesions. He was investigated with radiography, high- resolution computed tomography and magnetic resonance of the chest, which revealed multiple small and large nodules with random distribution, mostly in the lower lungs zones. Biopsies of lung and skin lesions was performed and the diagnosis of secondary syphilis was defined. Other laboratories tests (venereal disease laboratory and FtA-abs) corroborated the diagnosis. The patient was treated with penicillin, and the pulmonary and skin lesions regressed in the follow- up examinations.
