Figure 5b. (a) On a coronal T1-weighted MR image of the chest and abdomen, the mass has low signal intensity with high-signal-intensity cystic areas corresponding to those seen at prenatal US, a finding that suggests the presence of hemorrhage. Both adrenal glands are visualized (arrows), with the left adrenal gland being displaced inferiorly by the mass. (b) On an axial T2-weighted MR image of the abdomen, the mass is markedly hyperintense relative to the adrenal glands (arrows).
