Atypical Presentation of Perforated Viscus as Biliary Colic.

Peptic ulcer is a defect in the mucosal layer of the stomach or duodenum that extends into the deeper layers of their walls. Patients with peptic ulcer disease (PUD) may be asymptomatic or have mild abdominal discomfort. It is one of the common etiologies of perforated viscus resulting in secondary peritonitis, a life-threatening condition that carries high risk for morbidity and mortality especially in those who present late to the hospital or due to unrecognized and misdiagnosed perforation. Early detection of perforation of peptic ulcers should be based on clinical data and imaging techniques. We report a case of a 56-year-old female who presented to our ED with right upper quadrant (RUQ) pain radiating to the right shoulder, alleviated by food, and not aggravated by anything. On examination, the patient was vitally stable, tenderness in the RUQ was appreciated, and Murphy sign was positive. Thus, she was diagnosed with perforation of anterior first part of the duodenum. What makes our case peculiar is the presentation of biliary colic in the setting of perforated peptic ulcer.
