Abstract

Phrygian cap and its rare relative, pseudo-duplication of the gallbladder, are two radiologic findings that may be revealed on ultrasound evaluation. Correct identification of Phrygian cap and pseudo-duplication should trigger a careful survey of the gallbladder in its entirety to rule out pathology. These anatomic variants may lead to partial under-distension of the gallbladder and can cause the gallbladder wall to appear falsely thickened. Asymptomatic patients with this finding may be safely discharged while symptomatic patients may require further surgical consultation.
