We present a case of bacterial emphysematous cystitis in a 59-year-old woman who presented with behavioral changes, aggression, visual hallucinations, unintentional weight loss, fecal incontinence, and occasional diarrhea for two months. The diagnosis was suspected by abdominal ultrasound and confirmed by abdominal computed tomography. This highlights the importance of imaging as a diagnostic tool for emphysematous cystitis, particularly point-of-care ultrasound in the emergency department, due to its sensitivity and freedom from radiation.Englishhttps://yemenjmed.com/admin/abstract?id=84References1619Igand;uacute;zquiza Pellejero MJ, Torres Courchoud I, Navarro Aguilar ME.
