目的 探讨肺实性结节隐球菌病(PC)的影像学特点，提高肺实性结节隐球菌病诊断准确率?方法 回顾性分析20 例一共107 个肺实性结节(≤ 3 cm)，肺隐球菌病患者的CT 影像表现?结果 该组20 例患者均行穿刺活检，患者口服氟康唑抗隐球菌治疗后随访复查， 18 例患者3~6 个月结节明显缩小，6~12 个月基本吸收，2 例患者结节2 年后才基本吸收并残留少量纤维灶?本研究结果显示:20 例患者中病灶位于胸膜下?肺外带分布18 例，共105 个结节，内带分布2 例，共2 个结节;病灶单发9 例，共9 个结“,”Objective To investigate the imaging features of pulmonary solid nodule cryptococcosis (PC) and improve the diagnostic accuracy of pulmonary solid nodule cryptococcosis. Methods The CT findings of 20 patients with 107 solid pulmonary nodules (≤3 cm) and pulmonary cryptococcosis were analyzed retrospectively. Results All 20 patients in this group underwent puncture biopsy. Patients were followed up after oral fluconazole anti-cryptococcal treatment. 18 patients had nodules significantly reduced in 3 to 6 months， and basically absorbed in 6 to 12 months， and 2 patients had nodules 2 only a few years later did it basically absorb and leave a small amount of fibrous foci. The results of this study show: among the 20 patients， the lesions were located in the subpleural and extrapulmonary zone in 18 cases， a total of 105 nodules， and in the inner zone in 2 cases， a total of 2 nodules;single focus in 9 cases， 9 nodules in total， 2 lesions in 2 cases， 4 nodules in total， multiple lesions (≥3) in 9 cases， 94 nodules in total;the lesions had halo sign in 9 cases， a total of 26 nodules， and no halo sign in 11 cases， a total of 81 nodules;there was cavity in 1 case， a total of 1 nodule， and no cavity sign in 19 cases， a total of 106 nodules;there were 4 cases with thoracic traction sign， a total of 8 nodules， and 16 cases without pleural traction sign， a total of 99 nodules;one case had deep lobulation， a total of 1 nodule， 18 cases had shallow lobulation， sharing 103 nodules， 1 case had no lobulation， sharing 3 nodules;the maximum short diameter (≤1 cm) was 10 cases， and the maximum short diameter (>1 cm) was 10 cases;mediastinal lymphadenopathy in 2 cases and no mediastinallymphadenopathy in 18 cases;there was no calcification in 20 cases. Conclusion Pulmonary solid nodules are located in the subpleural and extrapulmonary zone of the lung， without or shallow lobulation， no traction sign， mediastinum or mild lymphadenopathy， and may be accompanied by halo sign. The possibility of pulmonary cryptococcosis should be considered.
