Abstract
PURPOSE: Orbital inflammatory disease has been historically diagnosed with computed tomography (CT) and magnetic resonance imaging (MRI). Orbital ultrasound has served as a non-radiation alternative that has been successful at diagnosing many orbital pathologies but is not commonly used in clinical practice due to need for specialized ultrasound training and equipment needs. We demonstrate use of handheld ultrasound for detecting orbital inflammation. OBSERVATIONS: We present five patients with orbital inflammation where a handheld ultrasound probe was able to capture features consistent with concurrent CT scans. CONCLUSIONS AND IMPORTANCE: Handheld ultrasound is an accessible and portable method that can assist in the diagnosis and monitoring of orbital pathology.
