Ultrasound Artifact in an Unusual Site Simulating Bilateral Subdural Haematoma in a Neonate

摘要

Ultrasound (US) provides a simple way to assess the infant brain. However, all imaging modalities have some sort of artifacts. Some of them will cause diagnostic dilemma or even leading to mis-diagnosis. We report a case of an interesting US artifact which simulates a bilateral subdural haematoma in a term neonate. The basic physics of ultrasound and the cause of the artifact are briefly reviewed.
