Abstract
Although schwannoma may occur in any organ, it very seldom appears as an interpectoral lesion and rarely arises in the brachial plexus. We here report the case of a breast cancer patient with a schwannoma located in the interpectoral space that mimicked a metastatic lymph node with various imaging modalities, including ultrasonography, magnetic resonance imaging, and positron-emission tomography/computed tomography. Awareness of its location and imaging features on various modalities is helpful for identifying schwannoma mimicking a metastatic interpectoral lymph node in breast cancer patients without axillary level I lymph node metastasis.
