Hyperdense is a CT term describing tissue that appears brighter (whiter) than expected — usually because it is denser than surrounding tissue.
It is an imaging finding, not a symptom. The clinical picture depends on the underlying cause.
On CT, hyperdense findings often correspond to bone, calcification, fresh bleeding, contrast, or metal — the location and pattern tell the radiologist which one.
Reading hyperdense findings in context (location, shape, history, other findings) is a core part of CT interpretation.
Management depends entirely on what the hyperdensity represents — calcified vessel, kidney stone, intracranial bleed, or contrast in the right place.
