Brain abscess, MRI sequence

Référence de la vidéo 11940498
Brain abscess. Sequence of sagittal magnetic resonance imaging (MRI) scans showing the a large abscess in a patient's brain. The abscess is a swelling caused by accumulation of pus, and is seen in the left frontal lobe. It is large, well defined, peripherally enhancing (bright around edges), and surrounded by parenchymal oedema (fluid build-up). There is some accumulation of mucus in the sinuses (left frontal, left ethmoid, and both maxillary sinuses) and mild opacification of the mastoid air cells (seen as black areas), bilaterally (both sides). The abscess and surrounding oedema are causing various distortions to structures within the brain, most notably effacement (obscuring) of the left ventricle, right frontal horn and local sulci (grooves between folds in the cerebrum).
