POCUS IOTW: Mandibular Swelling

Posted on: March 14, 2018, by :

6 year old boy with right lower mandibular swelling s/p trauma after family member hit him in the face with a blunt object.

Initially thought to be a hematoma but on ultrasound as seen below there was a string of enlarged lymph nodes.  To differentiate a lymph node from an abscess or a hematoma, look for the stalk within the lymph node that usually lights up with color.  The other side of the face was also imaged and no lymph nodes were noted.

Upon further history and physical, the patient was found to have a tooth abscess and will follow up with dental as an outpatient.
