Bedside detection of acute epidural hematoma by transcranial sonography in a head-injured patient.

Transcranial ultrasonography was performed in a 24-year old patient, brought to the ICU after a motor vehicle accident. A small (max width 0.9 cm) temporal epidural hematoma was observed. Transcranial echography may be a useful tool to monitor epidural hematomas before clinical conditions deteriorate. In all patients with a sufficient acoustic window in the temporal bone, it is a rapid and non-invasive neuroimaging technique that can complement the results of CT scan, and may help to reduce delays in surgical managem
