Figure 2
Figure 2 Magnetic resonance images of the patient. A and B show the axial T2-weighted fat suppressed MR images of the pelvis. A heterogeneous but predominantly high signal intensity tumor mass (T) is seen arising from the right lateral wall (arrow) of the rectum (R). This mass extends anteriorly to invade both seminal vesicles (S) and abuts and displaces the prostate gland (P). A high signal focus in the left acetabulum represents a bone metastasis (M). The bladder is noted as B. C is the MR image about 5 wk later, now repeated with contrast. T1-weighted post-contrast fat saturation MR image correlating to image in Figure 2b shows rim enhancement of the mass with a large central low signal area consistent with central necrosis. There is now invasion of the tumor into the prostate gland (P) and multiple new osseous metastases (M).
