The diagnosis was suggested by the computerized tomographic (CT)-scan showing central hypodense areas after contrast, and was subsequently proved by mediastinoscopic biopsy with histological and microbiological analysis. The atypical presentation of tuberculosis together with a negative two-step 5 international units of purified protein derivative (IU-PPD) tuberculin skin test and a frequent contact with a cavernous index case points towards a primary infection in this patient.
