Mentions: Several MR imaging criteria for ECE have been used. Table 1 presents commonly used criteria for ECE with its specificity and sensitivity. Most frequently used criteria are asymmetry of the neurovascular bundle, obliteration of the rectoprostatic angle and bulging of the prostate capsule (Fig. 1). SVI is detected by an abnormal asymmetric low signal intensity within the lumen on T2-weighted images (Fig. 2). It should be noted that amyloid deposits, stones or blood could also cause low signal intensity of the seminal vesicles on T2-weighted images[14–17].Figure 2
