A Non-Resolving "Hematoma" Diagnosed as an Arteriovenous Malformation by POCUS

Michael Freilich et al. POCUS J. .

Abstract

Point-of-care ultrasound (POCUS) is a useful tool for the evaluation of soft tissue masses. We present the case of a patient with a mass on his forehead initially thought to be a slowly resolving hematoma. POCUS examination of the mass revealed a vascular structure more consistent with a post-traumatic arteriovenous malformation (AVM). This case illustrates how POCUS can be utilized to rapidly assess soft tissue masses and even identify unexpected vascularity.

Keywords: AVM; POCUS.
