Abstract

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. © 2010 Wiley Periodicals, Inc.
