ABSTRACT
Objective To investigate the value of 64-slice spiral CT angiography in diagnosis of the origin of abdominal large masses.Methods Twenty patients who were proven by operation and pathology to be abdominal massive tumor were collected in this study,tumor diameter average 17.8cm.All patients accepted plain and enhanced CT scanning,and their data were transferred to Philips IntelliSpace Portal.The tumor vessel were reconstructed with multiplanar reformation(MPR),maximum intensity projection(MIP),and volume rendering(VR).The origin of tumor were judged according to the feeding arteries by 2 attending physician,and the results were compared with pathology.Results Of these 20 cases,15 cases were malignant tumor,5 benign.Blood supply arteries were found in 19 patients,36 vessels.Lateral branch vessels in 6 cases and arteriovenous fistula in 4 cases.MSCTA findings were consistent with operation and pathology,with the accuracy of 90％.One case had no tumor vessel,one was misdiagnosed.Conclusion MSCT could be taken good use in diagnosis of large abdominal masses by tracking down the nourishing artery of masses.
ABSTRACT
A large mass as a sign of an infection is rare, and it might convince a physician that it had the appearance of a malignancy. The patient in this case visited our clinics after attending several hospitals, with a mass that had the appearance of a malignancy, based on the severe destructive findings observed on plain radiographs. We report the first documented case of a patient with a large mass (12×7×20 cm) and a low-grade infection, which developed at the proximal thigh after a hip arthroplasty. It is important to realize that an infection accompanied by a large mass, can mimic a highly destructive malignant lesion on plain radiographs.
