Abstract:
Objective To evaluate the spiral CT finding and diagnostic value of gastrointestinal stromal tumor.Methods The CT signs of gastrointestinal stromal tumor proved by pathologically and surgically in 25 cases were retrospectively analyzed .Results There were 9 cases of benign stromal tumor and 16 cases of malignant stromal tumor,including stromal tumor of stomach(18 cases),stromal tumor of esophagus(1 cases),stromal tumor of jejunum(4 cases) ,ileac stromal tumor(2 cases).All of them were single lesions,CT manifestations :(1) Plain scans demonstrated roundness or analogy-roundness mass,the edges of 8 cases with benign stromal tumor displayed clearly.The edges of 11 cases displayed unclearly in 16 cases of malignant stromal tumor and 7 cases of malignant tumors were lobulated,2 cases appeared small calcifications;(2 ) After contrast medium injection,there was enhancement in all cases.Enhancement was more obviously in arterial phase,however,the enhancement in venous phase was more extensive than that in arterial phase.Conclusion helical CT is a meaningful way to check patients with gastrointestinal stromal tumor.Helical CT dual-phase enhancement plays a significant role in judging benign or malignant stromal tumor,and has great value in clinic applications.
