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% reported. 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) epigastric discomfort was referred for ultrasound after suspicious cholecystitis. On radiological evaluation, a double “Phrygian cap” was found by coincidence. 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 indicated in case of recurrent symptoms. To our knowledge, sparse anatomic and ultrasound literature exists on the Phrygian cap, thus the need for this rare case report.
