Health Organization for Pudendal Education

Hi - would appreciate advice on my MRI with Doctor Potter. I can't work out how to paste into this slot but basically I will repeat the important bit here. Basically it said I don't seem to have entrapment at SS ligaments and the "pudendal nerves in the posterior margin of Alcock's canal appear unremarkable". However, "in the anteroinferior margin of Alcock's canal prominent varices are noted, particularly in the right. This directly abuts the pudendal nerve in the Alcock's canal and is noted immediately adjacent to the inferior perineal branches of the pudendal distribution. More inferiorly, varices surround both dorsal nerves to the penis. A frank varicocele is seen in the left hemiscrotum. Smaller varicolele is seen on the right".

Not sure what any of this means as have not seen anybody on this forum with the same problem. How do I sort this out? Dr Potter seemed to think I should have an injection into the Alcocks' canal.

Any advice very much welcome.

Seems that veins are responsible for entrapment perhaps after all. Although many have said that their presence is evidence of entrapment but it seems that with smaller nerves the veins themselves may be causing the entrapment. Violet had a post from Switzerland about it (sorry on phone so can't look easily for it )

Could in just indicate that there in entrapment in that area? That was my case that was confirmed by surgery. But that's interesting Violet, Helen about smaller nerves. Which would those be?

I was just thinking about the branches of the pudendal nerve Kate, as it divides after (usually) Alcocks canal, although I don't know how these compare size wise with say, face nerves associated with trigeminal neuralgia where it is known that low pressure systems like veins can be responsible for nerve entrapment.
When I re- read Violets post on vascular entrapments again it does state that the sciatic nerve can be entrapped by veins anyway. .. . .

"exploration of the pelvic nerves permitted confirmation of suspected diagnosis such as extensive endometriosis or a postsurgical fibrosis of the retroperitoneal space, but also permitted discovery of anatomical situations never suspected before such as the compression of the sciatic nerve by an atypical superior gluteal vein, the entrapment of the sacral nerve root S2 between the inferior gluteal vessels..."

So if that large nerve can be compressed this way, the pudendal nerve could be I guess anywhere along it's length just as Dr Possover describes in the article.
