Contrast-Enhanced Sonography of Juxtapleural Pulmonary Tuberculoma

ulmonary tuberculoma, often the result of healed pulmonary tuberculosis, usually presents as a solitary pulmonary nodule on chest radiography. Although it is only seen in 3% to 6% cases of postprimary tuberculosis on chest radiographs, it is one of the most common benign nodules, representing up to 12% to 25% of all solitary pulmonary nodules.1,2 Furthermore, in tuberculosisendemic countries, pulmonary tuberculoma is not an uncommon condition and often needs to be differentiated from other solitary pulmonary nodules.3,4 The characteristics of pulmonary tuberculoma on radiography have been well investigated. However, because of its discrete appearances, pulmonary tuberculoma is difficult to distinguish from other solitary pulmonary nodules (both benign and malignant) on the bases of radiography alone. Therefore, invasive methods, such as percutaneous biopsy and surgical confirmation, are often needed for a definite diagnosis.5,6 Bing-Sheng Cao, MD, Yu-Mei Liang, MD, Xiao-Lin Li, MD, Juan Deng, BD, Geng-Chen Zhang, BD
