Preferred Label : neurovascular bundle of prostate;
RADLEX synonyms : NVB of prostate;
Definition : PI-RADS: Nerve fibers from the lumbar sympathetic chain extend inferiorly to the pelvis
along the iliac arteries and intermix with parasympathetic nerve fibers branching
off S2 to S4. The mixed nerve bundles run posterior to the bladder, seminal vesicles,
and prostate as the pelvic plexus. The cavernous nerve arises from the pelvic plexus
and runs along the posterolateral aspect of the prostate on each side. Arterial and
venous vessels accompany the cavernous nerve, and together these structures form the
neurovascular bundles which are best visualized on MR imaging at 5 and 7 o'clock position.
At the apex and the base of the prostate, the bundles send penetrating branches through
the capsule, providing a potential route for extraprostatic tumor spread.;
