The differential diagnosis is broad (Table 18-1), and the workup often requires multiple diagnostic tests. Ultrasound is the initial diagnostic imaging modality of choice in the majority of cases. Point-of-care ultrasound (POCUS), performed and interpreted by the clinician and completed at the time of the initial physical examination, helps narrow the differential diagnosis and may eliminate the need for further diagnostic testing.
