ABSTRACT

Objective To improve our knowledge by analyze the image findings of stromal tumor at small intestine.Methods The image findings in 23 cases with pathological-proved small intestinal stromal tumor were retrospectively analyzed as follow:image examine with GI(11 cases),DSA(2 cases),B-us(13 cases) and CT(all cases).Results The tumors originated from the duodenum(n=5),jejunum(n=11) or ileum(n=8).Found by GI(n=2),DSA(n=2),B-us(n=12) and CT(n=21).The lesions were mainly round or oval in shape.On plain CT scans,the tumors showed low-density centrally with isodensity peripherally(n=17),or homogeneous isodensity(n=4),or cystical low-density(n=2).On enhanced CT scans,moderate or marked enhancement was seen in most cases.Conclusion It has some spacial findings by image examination about small intestinal stromal tumor,include:well-defined margins,markedly enhancement,no metastases to local lymph nodes and the common clinical symptoms.CT and B-us are the mainly examination,therefore,a confirmed diagnosis relies on the pathological examination.
