What does this ultrasound clip demonstrate?
Reveal Answer
- This clip shows a small, well defined peripheral lung metastasis in an emphysematous lung.
- There is a well defined hypoechoic solid
lesion. It is within the lung and slides with respiratory movement. The
regular, rounded borders are unlike the irregular, poorly defined
“shredded” borders of pneumonia, and unlike the wedge shape one can see
with pleural infarction. The rounded convex surface at the pleural
surface is also evident. These features are typical of a small rounded
peripheral lung metastasis. - Further examination revealed these were numerous.
- The lung surface is particularly smooth and
devoid of the normal comet tail artefacts and occasional B-lines. This
is characteristic of emphysematous lung.
