Photograph of sagittal gross anatomic slice shows interscalene triangle in 76-year-old male cadaver with arms positioned alongside body. Interscalene triangle is bordered by anterior scalene muscle anteriorly and by middle and posterior scalene muscles posteriorly.

Sagittal T1-weighted MR images of 32-year-old male volunteer with arms positioned alongside body (B) and with arms hyperabducted (C) show interscalene triangle. In C, note narrowing of space between posterior side of clavicle and anterior side of anterior scalene muscle (prescalene space) when compared with B.
