Abstract:
PURPOSE: To present CT findings of benign mass-like nodular lesions associated with chronic tuberculousempyema. MATERIALS AND METHODS: We retrospectively reviewed the CT scans of nine patients with mass-like lesions associated with chronic tuberculous empyema, which were pathologically (operation=4, US-guided biopsy=3) or clinically (n=2) confirmed as benign lesions. Shape, number, size, presence of calcification and enhancement pattern of mass-like lesions were assessed. RESULTS: In all patients, chest CT showed unilateral calcified pleural thickening, with mass-like nodular lesions. Fluid within the pleural cavity was observed in eight patients. CT findings of mass-like lesions were multiple and nodular (n=9). Calcification was demonstrated within the lesions in four patients. In each case, the size of the largest nodules was 1-3cm in diameter. In contrast, CTshowed mild (n=6) to moderate (n=2) enhancement compared with adjacent muscles. The pathologic results ofmass-like lesions were chronic inflammation (n=3) and necrosis (n=4). CONCLUSION: Benign mass-like lesions associated with chronic tuberculous empyema appeared as multiple nodules varying in size from 1 to 3cm in diamter, with slight enhancement.
