Gastrointestinal stromal tumors (GIST) have been suggested to be the most common neurofibromatosis 1-associated gastrointestinal tumors. This case report describes and compares US and CT findings of both abdominal neurofibromas and a gastrointestinal stromal tumor. On US, the GIST appeared as a well-defined inhomogeneous lesion with a target-like pattern similar to CT. The neurofibromas appeared as well-demarcated round nodules with a relatively homogeneous hypoechoic internal structure and were accompanied by subtle posterior acoustic enhancement. US and CT were able to differentiate between neurofibromatomas and GIST in this neurofibromatosis 1 patient; however, a biopsy of the suspicious mass was performed to clarify the diagnosis.
胃肠道间质瘤（GIST）被认为是最常见的与神经纤维瘤病1型相关的胃肠道肿瘤。本病例报告描述并比较了腹部神经纤维瘤和胃肠道间质瘤的超声和CT表现。在超声检查中，GIST表现为边界清晰的不均匀病变，具有类似于CT的靶样模式。神经纤维瘤表现为边界清晰的圆形结节，内部结构相对均匀低回声，并伴有轻微的后方回声增强。超声和CT能够在该神经纤维瘤病1型患者中区分神经纤维瘤和GIST；然而，对可疑肿块进行了活检以明确诊断。
