Diagnosis: tuberculous cold abscess. Technique: standard chest radiography and contrast-enhanced chest CT. Description: A 26-year-old man with marijuana abuse presented with acute back pain of two-week duration. There was no weight loss, no night sweats or fever. Postero-anterior and lateral chest radiographs (a, b) show a well-delineated mass-like lesion posterior in the left lung. Contrast-enhanced CT in the mediastinal window setting (c, d) shows a heterogeneous mass with intralesional necrosis and focal bone destruction (arrow) of the adjacent rib, best seen in the bone window (e). Transthoracic CT-guided biopsy was performed. Histopathologic examination of the specimen confirmed the diagnosis of a tuberculous cold abscess
