Abstract:
Objective To evaluate the CT features of solitary inflammatory nodules of the lung. Methods CT features in twenty-three cases of solitary inflammatory nodules of the lung confirmed by operation or clinical were analyzed retrospectively. Spiral CT including plainscans and contrast enhanced scans was done in all patients. Thin-slice target scan and multiple plane reconstruction were used on the area of nodule. Different width and level of window were used to show the characteristic sign of the nodule.Results No calcification,satellite lesion,concentrated vessels and enlarged lymph nodes were found in or around all of the nodules. The size of these nodules were 10 mm?15 mm~30 mm?40 mm with round or irregular margin. Superficial lobular or spiculated margin was seen in only three nodules. Hyperemia and clouding appearance were found in 19 nodules and reflecting thickening pleura in 18 nodules. Unsteady edge enhancement were found in 18 nodules and no enhancement in 5 nodules. Effused change around the nodules could be seen perfectly when the level was about -400. MPR was the most accurate technique to show the relationship of nodule and pleura. Conclusion Solitary inflammatory nodules of the lung have obvious CT characterizes. By analyzing various CT manifestations comprehensively most nodules can be diagnosed correctly. Suitable width and level of window as well as MPR are helpful in showing the characterizes of the nodules.
