Hypodense is a CT term describing tissue that appears darker (less bright) than expected — usually because it is less dense than surrounding tissue.
It is an imaging finding, not a symptom. The clinical picture depends on what the hypodense area represents.
On CT, hypodense findings can mean fluid (cyst), fat, old infarct, oedema, or a low-density mass — the location and shape help separate them.
Reading hypodense findings in context is part of CT interpretation; sometimes contrast is needed to characterise them further.
Management depends on what the hypodense finding represents, which usually requires combining imaging with clinical history.
