What does prominent interstitial markings bilaterally means?

Chest x-ray feature: "prominent interstitial markings bilaterally" describes a way that a chest x-ray looks. The lungs normally look dark on an x-ray, with faint whitish lines here and there. The faint lines are called interstitial markings. When they become more noticeable, by becoming more white or wider in size, they are called "prominent". Causes vary, depending on age, symptoms, and known or suspected illnesses.

X-ray Findings: This phrase is often used to describe the appearance of a person's lungs on a chest x ray. It can, but may not necessarily, mean an excess of fluid within the lungs framework, suggesting fluid build-up due to heart related dysfunction. A great question for your personal internist and/or radiologist.

Chest X-ray?: I assume you mean on a chest x-ray? It can mean a lot of things, including old scarring, new infection or fluid overall.

What else?: Prominent interstitial markings could mean either fluid overload or infection; it is important to know what other symptoms are present.

It depends: This is a common description on a chest x-ray that means the radiologist feels the tissue around the small air tubes (bronchioles) in the lungs are prominent. This would be common in a viral respiratory infection and other causes of lung inflammation like asthma or even possible fluid from heart problems.
