Objective To analyze the MSCT manifestations of septic pulmonary embolism(SPE)to explore the diagnosis value of MSCT.Methods The MSCT findings of eight patients with SPE were analyzed retrospectively.Results ① Of all 177 lesions,84 lesions located in both upper lobes,25 lesions located in right middle lobe and 68 lesions located in both lower lobes.② There were 106 nodules and 44 wedge shaped opacities in all the 8 cases,of which the 88 nodules (83.0%)and all of the wedge shaped opacities located in sub-pleural zones of the lung and the 18 nodules (1 7.0%)located in the inner and middle lung fields.In 6 cases,the 26 nodules (24.5%)and the 1 6 wedge shaped lesions (38.1%)had “feeding vessels”.③ There were 27 patchy shadows in 6 patients,of which 12 patchy shadows (44.4%)had air bronchogram.④ There were 18 cavities in 6 patients,of which 14 cavities (13.2%)located in nodules and 4 cavities (9.1%) in the wedge shaped lesions.There were 8 cysts in 4 patients,of which 6 cysts located in nodules (5.7%)and 2 cysts in the wedge shaped lesions (4.5%).⑤ The nodules and the wedge shaped lesions were enhanced slightly.⑥ Pleural effusion and pericardial effusion were found in 4 and 3 patients,repectively.⑦ Of 6 patients the follow-up MSCT scan in a short period showed the disease progressions. Conclusion SPE has characteristic manifestations in MSCT,and MSCT can provide valuable information for the diagnosis of SPE.
