Today I went to see another orthopedist, just to be sure about the weird tear drop shaped spots on my previous pelvic X-ray (here). Mind you that those previous radiographs were taken about 20 minutes apart, so I figured it couldn’t be merely a fluke of the equipment or film. I was surprised I could actually get an appointment the same day. I told the schedular person that I had possible radiolucency in my pelvic radiographs and told her about my situation. I’m sure she didn’t quite expect that.

And the doctor looked at my radiographs and immediately knew what it was.

“Bowel gas”, he said.

At first, I really wasn’t buying this. I mean, if you took a ballon and put it in front of a concrete wall, you couldn’t see through the wall. Photons visible to us don’t behave this way, so why should higher energy X-rays? They are after all just photons. And it’s not like there’s some weird quantum tunneling going on here. And it’s not back-scattering either, as the emitter has no imaging film in it.

I was hoping to get a CT scan of my pelvis out of this, just to make sure everything was ok. I told him that maybe I asked the other guy so many questions that he didn’t notice this. After all, it is very subtle. He showed me a few test radiographs where there was pronounced bowel gas and they had similar “dark ghosts” throughout the pelvis, roughly where the colon would have lied. Some larger, some more dark, etc.

We talked about it some more and I agreed that if there were no spots in the same place, all was probably ok. He offerred to take another radiograph:

This radiograph was different, in that I stood up this time instead of laying down. The radiographer told me to touch my toes, but point my ankles out. At first, I thought she said feet together, so I asked. I told her that’s what the previous tech had me do. She was baffled why anybody would do that. So I asked her why and she said that when you stand that way, you get a better visualization of the trochanters (I think it was the trochanters).

And as you can see, about 6 days out that the spot is not there, but there is another spot further up on my pelvis. It too is bowel gas. He said that my pelvis looked perfectly healthy, that the arches at the top of my leg bone were well defined and nicely curved. He said I shouldn’t worry about this and go and get my jaw tumor fixed.

And that was re-assuring.

Pano Radiograph

This was the third panoramic radiograph (Xray) I had done. This one was done after the loud “pop” I heard, to make sure that I didn’t fracture my jaw. If there was a fracture, it’s only a hairline and not really evident here.

Pano Radiograph

This was the second panoramic radiograph (Xray) I had done. Notice the radiolucency on the left side. It’s fairly visible here, with these settings. At this time, it was thought it was a cyst.
