A member asked:

Why isn't this bluish oral lesion showing on a c-scan? ent says it is a vessel and needs to be removed or checked every 6 months due to bone erosion.

Ct scan: CT scans show bone very well, not soft tissues. For that an MRI is best. Most likely your ENT is following your CT because if the lesion is growing, it will invade your bone and that part is visible on the CT. If your lesion does not do that, you would not need to remove it. So, not seeing the lesion is expected and good news.

Bluish oral lesion: If it's a soft tissue lesion it will not appear on a CT scan. Better visualized on an MRI. Some blue lesions are neoplastic, others are vascular and benign. see your Dentist for an examination.
