The purpose of this study was to investigate the prevalence of the nodular reverse halo sign (NRHS) in chest computed tomography (CT) in patients with active pulmonary tuberculosis.
From March 2018 to March 2019, 29 consecutive patients with a culture-confirmed active pulmonary tuberculosis and who underwent chest CT examination during hospital-admission were retrospectively included in the study. There were 24 men and 5 women with a mean age of 40.9±16.7 (SD) years (range: 18-80years). Chest CT examinations of included patients were evaluated for the presence of NRHS and other tuberculosis-related CT signs.
CT revealed the NRHS in 5 patients (5/29; 17%). The other CT signs of tuberculosis included consolidations in 18 patients (18/29; 62%), tree-in-bud pattern in 14 patients (14/29; 48%), cavitation in 12 patients (12/29; 41%), sparse nodules in 10 patients (10/29; 34%), and pleural effusion in 8 patients (8/29; 28%).
CT shows NRHS in 17% of patients with active pulmonary tuberculosis, indicating that the sign is not as rare as previously thought in patients with this condition.
本研究旨在探讨结节状反向晕征（NRHS）在活动性肺结核患者胸部 CT 中的发生率。
本研究回顾性纳入了 2018 年 3 月至 2019 年 3 月期间 29 例经培养证实的活动性肺结核且住院期间接受胸部 CT 检查的患者。患者中有 24 名男性和 5 名女性，平均年龄为 40.9±16.7（SD）岁（范围：18-80 岁）。对纳入患者的胸部 CT 检查结果进行评估，以确定是否存在 NRHS 和其他与结核病相关的 CT 征象。
5 例（5/29；17%）患者 CT 显示 NRHS。其他结核病 CT 征象包括：18 例（18/29；62%）患者存在实变影，14 例（14/29；48%）患者存在树芽征，12 例（12/29；41%）患者存在空洞，10 例（10/29；34%）患者存在稀疏结节，8 例（8/29；28%）患者存在胸腔积液。
CT 显示活动性肺结核患者中 NRHS 的发生率为 17%，表明该征象在该类患者中并不像之前认为的那样罕见。
