Hi All,
I’m attaching a case in powerpoint, would appreciate any input as to what this might be, what further workup is appropriate etc.
Thank you!

Hi All,
Thank you very much for your replies. Most people felt that the findings could represent notochord remnants, and conservative follow-up was recommended.
Please see below MR image of the pelvis from 12 years ago (unrelated to the current indication). The image is low-resolution, but the process does appear to be new since then. If truly new since 12 years ago, would notochord remnant/chordoma still be on the differential?
Seven months ago, the patient had transrectal injection of botox to the levator ani, and 3 months later developed pus drainage 1 cm posterior to the anus. His surgeon told him that there was some complication during injection but was not specific. Could this process be related to that? Chronic inflammation/granuloma formation?
Meanwhile a surgeon who specializes in sacral surgery has recommended resection and advised against imaging follow-up (fearing progression of possible chordoma).
Thank you!
Sam
