[A case of intrahepatic cholesterol stone complicated with atrophy of the anterior superior ventral and anterior superior lateral subsegments (S8ab) of the liver].

A 61-year-old male patient with intrahepatic cholesterol stone is reported. Stones were detected in the anterior superior lateral subsegment (S8ab) of the right lobe with bile duct stenosis, the lateral anterior segment (S3) of the left lobe, and the left caudate lobe (S11). Partial hepatectomy including S8ab, S3 and S11 was performed to remove all stones. Atrophy of S8ab was diagnosed by CT, and PTP clarified the patency of the subsegmental portal vein (P8ab). This is a rare case with cholesterol intrahepatic stone with regional bile duct stenosis and subsegmental atrophy of S8ab of the liver.
