We report a case of Caplan syndrome complicated with tuberculosis, which was clinically followed up for 18 years and underwent autopsy. Initial chest radiograph showed 2 large nodules against the background of smaller pneumoconiotic nodules. One of the large nodules showed cavitation during follow-up. Computed tomography (CT) was helpful in identifying calcification in another large nodule. Autopsy confirmed the 2 large nodules as burned-out rheumatoid nodules and revealed additional rheumatoid nodules that were indistinguishable from silicotic nodules by CT.
我们报告一例合并肺结核的卡普兰综合征病例，该病例进行了18年的临床随访并接受了尸检。最初的胸部X线片显示，在较小的尘肺结节背景下有2个大结节。随访期间，其中一个大结节出现空洞。计算机断层扫描（CT）有助于识别另一个大结节中的钙化。尸检证实这2个大结节为陈旧性类风湿结节，并发现了其他类风湿结节，CT显示这些结节与矽肺结节无法区分。
