Figure 5d. Four different prostate cancer cases with extracapsular extension of the tumor (T). T2-weighted axial MR images show an asymmetric bulge and spiculated margin (arrow in a), obliteration of the rectoprostatic angle (arrow in b), breach of the capsule with direct tumor extension and envelopment of the neurovascular bundle (arrow in c), and asymmetry of the neurovascular bundles (arrows in d).
