Figure 1b. Cavernous hemangioma in a 46-year-old man. (a) Axial T1-weighted (repetition time msec/echo time msec = 600/12) magnetic resonance (MR) image obtained with a surface coil at the level of the liver (L) shows an ill-defined soft-tissue mass in the right chest wall. The tumor appears as an area of heterogeneous hyperintense signal relative to the signal intensity of adjacent muscle (arrows). (b) Axial gadolinium-enhanced T1-weighted (600/12) fat-suppressed MR image shows heterogeneous enhancement and distended vessels (arrow) in the tumor.
