What does “Annular tear” mean on a radiology report?
A small split in the tough outer ring (annulus) of a spinal disc. Very common on spine MRI, often age-related, and frequently found in people without back pain.
How "Annular tear" is used in radiology reports
Each spinal disc has a soft centre and a tough outer ring of fibres called the annulus. An annular tear (the formal term in the shared spine vocabulary is "annular fissure") is a small separation between or through those fibres. On MRI it often shows as a small bright line or spot at the back of the disc, which some reports call a "high-intensity zone".
Annular tears are part of ordinary disc ageing. They are found on MRI in many adults who have no back pain, and they often appear alongside disc bulges and loss of disc water content (desiccation). Despite the word "tear", they are not an injury in the sense of a sudden rupture, and the finding does not on its own mean the disc is about to herniate.
Whether a tear is relevant to someone’s pain is debated in the research and cannot be settled from the image alone. As with other degenerative spine findings, the doctor matches the scan to the history and examination. The report will say separately if a disc is pressing on a nerve, which is usually the part that matters more.

Does this mean something is wrong?
Not on its own. A radiology report describes what the images show, in language written for the doctor who ordered the scan. One term is rarely the whole picture — what it means for you depends on why you were scanned and what else the report says.
If the report worries you, the person who can actually answer that is the doctor who referred you. Understanding the words first usually makes that conversation a better one.
Want your whole report explained?
One term is a start. Radily reads your full report and explains it in plain English — and can talk you through it on video, so you are not reading medical language alone.
