Abstract
It is debatable among anatomists whether the
Phrygian cap of the gall bladder is an anomaly or
anatomic variation with an incidence of 4.0% re ported. A 2-fold increase of 7.9% during a 5-year
population study was observed in Lagos, Nigeria.
A 48-year old male with minimal (non-acute) epi gastric discomfort was referred for ultrasound after
suspicious cholecystitis. On radiological evalua tion, a double “Phrygian cap” was found by coinci dence. There is no recent emphasis on double
Phrygian cap study, thus it is reported for its rarity
and difficulty in arriving at conclusive diagnosis.
Common imaging choice is mostly by multi-slice
CT for biliary aspects and appendages. Most
Phrygian caps are asymptomatic with little or no
pathologic consequence. Surgical intervention
(cholecystectomy) for a Phrygian cap is only indi cated in case of recurrent symptoms. To our
knowledge, sparse anatomic and ultrasound litera ture exists on the Phrygian cap, thus the need for
this rare case report.
