Fibroma in a 44-year-old woman. (a) Axial, (b) coronal and (c) sagittal T2-weighted images show a polilobulated solid mass (white arrows) with homogeneous low signal intensity. (d) Axial and (e) coronal contrast-enhanced fat-suppressed T1-weighted images show the homogeneous enhancement of the lesion (white arrows). (f) Photomicrograph (H&E X20) shows closely packed spindle stromal cells arranged in storiform pattern with hyaline bands
