Abstract：Objective To examine why stromal tumor was misdiagnosed as gynecologic tumor by ultrasound and CT examination. Methods Two cases of stromal tumors that were misdiagnosed as gynecological tumors were respectively reviewed and a review of 33 reports with a total 61 cases in the literature was conducted. Results There were 51 cases of gastrointestinal stromal tumor (GIST) and 12 cases of extra-gastrointestinal stromal tumor (EGIST) in the literature. A total of 84.1% of the patients received B-ultrasound imaging. GIST close to the pelvic (the pelvis, uterus, accessory area) accounted for 91.5%, and the remaining 8.5% were close to the abdominal cavity, in which 4.3% had positon changes by B-ultrasound scanning, suggesting that the mass may be derived from the intestinal tract. 66.7% of EGIST were close to the pelvis and 33.3% were close to the abdominal cavity. 31.8% of the cases received CT scan. One-third of the cases were suggestive of gut origin. Majority (70.6%) of GIST were of small intestine origin, followed by small bowel mesentery, ileum, stomach, jejunum, colon, right colon, cecum, appendix, and intestine with no origin being specified. 9.8% of cases had metastasis to the accessories/uterus and 11.8% with involvement of the gynecologic system. EGIST from the abdominal cavity, ovary, broad ligament, uterine bladder peritoneal reflection, and the vaginal wall were 33.3%, 25.0%, 16.7%, 8.3%, and 16.7%, respectively. Conclusion The diagnosis of GIST and EGIST is difficult by imaging and differentiation between the attachment and gynecological tumors is required. CT examination of the stromal tumor localization is slightly better than ultrasound.
