Objectives The purpose of this study was to describe the findings juxtapleural pulmonary tuberculoma on contrast-enhanced sonography and investigate their correlation with histologic findings. Methods From April 2008 2012, 21 patients biopsy or clinically proven tuberculomas underwent an intravenous bolus injection 4.8 mL a sulfur hexafluoride–filled microbubble contrast agent. Enhancement patterns functional parameters (time enhancement, time peak signal intensity) derived from time-intensity curve were evaluated. correlated Results A rim enhancement pattern presented in 12 (57.1%), homogeneous 5 (23.8%), heterogeneous 4 (19.1%) tuberculomas. pathologic confirmed that nonenhancing center corresponded caseous liquefied necrosis, homogeneously enhanced portions granulomatous inflammation. medians (25th–75th interquartile ranges) for intensity 14 seconds (9–14 seconds), 22 (21–26 83 dB (55–92 dB), respectively. Conclusions Contrast-enhanced is feasible. Juxtapleural usually show rim, homogeneous, enhancement. are well features.
