Pathology of "Phrygian Cap" deformity of the Gallbladder

Dr Sampurna Roy MD


The “Phrygian cap” deformity occurs when the fundus of the gallbladder is folding over the body of the gallbladder.

A Phrygian cap is a congenital abnormality of the gallbladder and has an incidence of 4%.  It is the most common congenital anomaly of the gallbladder and can simulate a mass in the liver during hepatobiliary imaging,which may suggest a tumor.

This anatomical variation was first described by Boyden in 1935. He named the deformity after the Phrygian cap, an ancient conical cap with the top pulled forward This cap is associated with the inhabitants of Phrygia, a region what is now called central Turkey.

In many cases with “Phrygian cap” deformity, a mucosal fold is created, which partially subdivides the lumen of the organ.

A Phrygian cap is a benign anatomical abnormality and normally causes no symptoms. Sometimes patients complain of pain in the right upper quadrant of the abdomen. The Phrygian cap is of no clinical importance other than to not mistake it for pathology.
