Large extraluminal gastrointestinal tumors (GISTs) may present as pelvic masses and thus mimic gynecological neoplasms in female patients. On clinical examination and pelvic ultrasound, these tumors resemble pedunculated fibroids or ovarian tumors. Multidetector computed tomography (CT), with its ability to perform isotropic multiplanar reconstruction, is useful in differentiating GISTs from true gynecological masses by demonstrating the pedicle sign connecting a pelvic GIST to its organ of origin. This allows a preoperative diagnosis to be made, which may be helpful in guiding therapeutic options and management. We present two cases of GISTs presenting as pelvic masses in which ultrasound findings suggested a gynecological cause, but multidetector CT with multiplanar reconstruction was able to determine their true organ of origin.
大的腔外胃肠道肿瘤（GISTs）可能表现为盆腔肿块，因此在女性患者中类似于妇科肿瘤。在临床检查和盆腔超声中，这些肿瘤类似于有蒂的肌瘤或卵巢肿瘤。多排螺旋 CT 具有各向同性多平面重建的能力，通过显示连接盆腔 GIST 与其起源器官的蒂征，有助于将 GIST 与真正的妇科肿块区分开来。这可以做出术前诊断，这可能有助于指导治疗选择和管理。我们介绍了 2 例 GIST 表现为盆腔肿块的病例，超声检查提示妇科原因，但多排螺旋 CT 多平面重建能够确定其真正的起源器官。
