Figure 15  Intrapectoral lipoma in a 45-year-old male with a palpable mass in the left breast. A: Mediolateral oblique; B: Craniocaudal mammography views showing a large, circumscribed fat density mass causing splaying of pectoralis muscle fibers in the left breast (arrows); C: Panoramic ultrasound image showing a circumscribed fat-containing echogenic mass in the intrapectoral location (arrow); D: Axial computed tomography image showing fat-containing mass splaying the pectoralis muscle (arrow); E-G: Magnetic resonance images (E: T1-weighted image; F: T2-weighted image; G: T1 fat-saturated image) demonstrating T1 and T2 hyperintense masses with suppression of fat saturation, suggestive of lipoma (arrows).
