I'll try to help if I can:

T6-7 right paracentral disc herniation deforms thecal sac -- this means the herniation is pushing on the thecal sac which is a membrane of dura matter that surrounds the spinal cord and cauda equina. The thecal sac is filled with cerebral spinal fluid.

T10-11 Bright signal at periphery of annulus on left representing an annular fissure.. A "signal means a measure of activity in nerve cells and is indicted by frequency of discharge. The Annulus is a ringlike part or structure and it has a slit.

At T11 there is a Hemangioma - this is a benign tumor of blood vessels that typically occur as purplish/reddish elevated areas of skin/tissue.

I hope I didn't completely confuse you. LOL If you have more questions, either post them here, or you can private message me too if you like. God bless and please take care. Hugs, Lee
