Abstract：Objective To analyze the MSCT performance of pulmonary angioinvasive aspergillosis .Methods CT ap‐pearances of 52 pulmonary angioinvasive aspergillosis patients proved by pathology or clinic were retrospectively analyzed . Results Multiple lesions (35 cases) mainly distributed in the peripheral areas of lung field (39 cases) .The shape of the lesions were nodules or tumors (38 cases) accompanied with halo sign (21 cases) ,15 cases of these 21 cases were hap‐pened in patients with hematologic malignancies .There were hypodense sign (13 cases) ,reversed halo sign (5 cases) ,air crescent sign or cavities (28 cases) ,and 49 (67% ,49/73)crescent sign or cavities .Among these 28 cases located near the hilar of the lesions ,9 enhanced cases presented border strengthen .There were totally 17 revisited cases ,presenting air crescent sign (7 cases) and cavities (4 cases) respectively performed after 2 and 4 weeks of halo signs .Conclusion Pul‐monary angioinvasive aspergillosis usually presented multiple nodules or tumors in the peripheral areas of lung field ,usual‐ly accompanied with halo sign or air crescent sign or cavities .The two latter signs usually located near the hilar of the le‐sions ,CT dynamic follow‐up has a diagnostic significance .The hypodense sign ,reversed halo sign and border strengthen in enhanced cases may help to diagnosis .
