Gallbladder Ascariasis : A Rare Case

İsmail Okan Yıldırım, Ayşe Aktaş


A 21 year-old female patient admitted to the emergency room complaining of right upper quadrant pain that had lasted for 6 months. The abdominal USG revealed hydropic gallbladder (89×40 mm) and the wall thickness was in normal limits. There was a linear undulant hyperechogenic membranous structure that was located along the bladder lumen with hyperechogenic and solid nodulations in the lumen. MRCP revealed undulant appearance and hypointensed curvilinear appearance with T2A in gallbladder. This made us think of a gallbladder aschariasis. Also, in the neck of the gallbladder there was a hypointensed stone in T1A and T2A. Because a stone was detected in both USG and MRCP, an elective laparoscopic cholecystectomy surgery was planned 10 days later. The pathologic examination confirmed the Ascaris lumbricoides. The gallbladder ascariasis is a rare clinical entity and the most reason is Ascaris lumbricoides. Numerous studies have been published about the gallbladder ascariasis and the majority of them were documented with USG as the primary modality. However Magnetic Resonance Cholangiopancreatography (MRCP) findings have been rarely reported. MRCP is a unique non-invasive method that demonstrates the gallbladder and bile duct ascariasis.

Key words: Gallbladder, ascariasis, US, MRCP
