Gastrointestinal stromal tumors (GISTs) represent 0.1-1% of gastrointestinal malignancies. They are commonly asymptomatic and found incidentally during laparoscopy, surgical procedures or radiological studies. Diagnosis is based on histology and immunohistochemistry, while the role of imaging studies is not diagnosis-specific. We present the case of a 38-year-old patient complaining of an increase in her abdominal circumference. Consequently, a vaginal examination, a transvaginal ultrasound and an MRI of the abdomen and pelvis were carried out. It should be noted that a preoperative diagnosis of GISTs is uncommon, due to the rarity and many presentations of the disease. Ultrasound and MRI are not able to differentiate a GIST from ovarian cancer. However, if a pelvic mass is detected, the possibility of a non-gynaecological tumor has to be considered.
胃肠道间质瘤（GISTs）占胃肠道恶性肿瘤的0.1%-1%。它们通常无症状，在腹腔镜检查、外科手术或影像学检查中偶然发现。诊断基于组织学和免疫组织化学，而影像学检查的作用并非特异性诊断。我们报告一例38岁女性患者，主诉腹围增加。因此，进行了阴道检查、经阴道超声检查以及腹部和盆腔的磁共振成像（MRI）检查。应当指出，由于该疾病罕见且表现多样，GISTs的术前诊断并不常见。超声和MRI无法区分GIST与卵巢癌。然而，如果检测到盆腔肿块，则必须考虑非妇科肿瘤的可能性。
