In short
Prominent bronchovascular markings, costophrenic angle blunting, cardiomegaly, opacity. Radiology reports use a vocabulary of description rather than diagnosis, and most of the alarming-sounding phrases are observations, not verdicts.
Emergency if: Severe breathlessness, chest pain, coughing blood, or blue lips alongside any chest X-ray finding — go to an emergency department now.

A radiologist describes; the report is not a diagnosis
A chest X-ray report is written by someone who has seen your image but usually not you. It records what the shadows look like, in standard descriptive language, and offers an impression of what could produce that appearance. The same appearance can come from several conditions, which is why reports so often end with a phrase suggesting correlation with the clinical picture.
That phrase is not evasion. It is the honest limit of the test: the image narrows the possibilities and your symptoms, examination and history choose between them. Reading the report without that context is how a normal-variant finding turns into a week of worry.
02
Markings, opacity and consolidation
Bronchovascular markings are the normal branching lines of airways and blood vessels. Calling them prominent or increased means they stand out more than average — a description that appears in smokers, in long-standing airway disease, in some infections, and in plenty of entirely healthy chests, especially on a film taken with a shallow breath. On its own it is a weak finding.
Opacity means an area looks whiter than expected, because something denser than air is occupying that space. Consolidation is a specific pattern of opacity where air in the small air sacs has been replaced by fluid or pus, and it is the appearance that fits pneumonia. An infiltrate is a looser term for the same general idea. None of these words specifies the cause by itself.
03
Angles, effusions and the diaphragm
The costophrenic angle is the sharp corner where the diaphragm meets the chest wall. Blunting of that angle means the crisp point has been rounded off, most often because fluid has collected at the base of the lung — a pleural effusion. Small effusions can follow infection, heart failure, or inflammation; a new effusion is usually worth explaining rather than watching.
The report may also comment on the diaphragm being elevated or flattened. Flattened diaphragms suggest lungs that are over-inflated and hold air, the pattern seen in long-standing airway disease. An elevated diaphragm on one side is often long-standing and harmless, but can reflect nerve or abdominal causes.
04
The heart shadow and cardiomegaly
Cardiomegaly means the heart shadow measures wider than roughly half the chest width on the image. It sounds definitive but depends heavily on technique: a film taken from front to back, taken lying down, or taken without a full breath all magnify the heart shadow. Portable X-rays taken at the bedside routinely over-call it.
Because of that, a chest X-ray is a screening observation about heart size rather than a measurement of it. If heart size genuinely matters, an echocardiogram measures the chambers directly and reports an ejection fraction — a very different quality of information.
05
Nodules, fibrosis, and knowing what needs a next step
A nodule is a small rounded density. Most small nodules seen on chest X-rays turn out to be benign — old healed infection, a small scar, or a skin lesion projected over the lung — but a nodule that is new compared with an older film, or that cannot be dismissed, is usually clarified with a CT scan rather than watched on X-ray. Comparison with any previous image is the single most valuable thing you can bring.
Fibrosis and reticular or reticulonodular shadowing describe scarring, where lung tissue has been replaced by stiffer tissue. Old scarring from healed infection is common and stable. New or spreading scarring warrants lung function testing and a specialist opinion, because the pace of change matters more than the word itself.
When to act
Routine — see a doctor
Prominent bronchovascular markings or a stable old scar with no symptoms: discuss at your next appointment and bring any earlier films for comparison.
Same-day — call promptly
A report describing consolidation, a new pleural effusion or a new nodule — arrange a medical review within a day or two rather than waiting.
Emergency — act now
Severe breathlessness, chest pain, coughing blood, or blue lips alongside any chest X-ray finding — go to an emergency department now.
