Radiologic findings that mimic malignancy.

Abstract

The purpose of this pictorial essay is to describe selected variant anatomy, benign pathology, and posttreatment appearances that may be incorrectly attributed to malignancy at cancer investigation. Radiologists involved in cancer staging should be aware of benign imaging appearances that simulate malignancy. Failure to correctly identify these findings as such may lead to unnecessary patient anxiety, incorrect tumor staging, and inappropriate treatment.
