Point-of-Care Ultrasound Diagnosis of Pneumoperitoneum in the Emergency Department.

Prompt and accurate diagnostic evaluation of the nontraumatic acute abdomen in the emergency department (ED) is crucial to lessen mortality burden. In patients with perforated viscus and pneumoperitoneum, point-of-care ultrasound (POCUS) can assist the emergency physician (EP) in the rapid bedside diagnosis. This report describes a case in which EP-performed POCUS led to the early detection and timely management of an atypical presentation of pneumoperitoneum.
