Stenosis

Stenosis means narrowing of a passage, such as a blood vessel, airway, spinal canal, or other tube-like structure in the body.

About this explanation

This entry explains common radiology language and when imaging may help. It cannot tell you what is happening in your specific case. Your official report, history, examination, and treating care team determine what the finding means for you.

When it may be urgent

Urgency depends on the organ involved. Narrowing that affects the brain, spinal cord, breathing, major blood flow, or bowel drainage may need rapid assessment.

Common symptoms

Symptoms depend on where the narrowing is and may include pain, weakness, dizziness, trouble swallowing, reduced blood flow, nerve symptoms, or shortness of breath.

When imaging helps

Imaging helps show where the narrowing is, how severe it is, and whether it is affecting nearby organs, nerves, or blood flow.

Why radiology matters

Imaging helps show where the narrowing is, how severe it is, and whether it is affecting nearby organs or tissues.

Usual management direction

Treatment may range from monitoring to medicines, stenting, surgery, or decompression depending on the site and symptoms.

What does Stenosis on a report mean for me?

This entry explains the word. If it appeared on your report, the next step is getting that report interpreted for your case.
