Hello - I had an MRI because I've had chronic tailbone pain. The results of the MRI show 1. Mild subchondral edema at the superior right sacroiliac joint, likely secondary to osteoarthritis and 2) 0.9 X0.6 cm rounded faint T1 hypointense, slight T2 hyperintense signal abnormality within the left sacral ala at the s2 segment. This likely is an incidental finding and may represent an atypical hemangioma or patchy red marrow hypoplasia. I'm being sent for a CT scan next week. The sacroliaic joints reamin unfused, there is no sacrololica join effusion or erosive change and no fracture is evident. There is a minimal STIR signal in the left sacral ala at the S2 region. Can someone please explain this to me in ENGLISH!
