A Case of Acute Acalculous Cholecystitis Associated with Gallbladder Amyloidosis

Abstract

An 80-year-old woman who presented with epigastralgia was found having a swollen, wall-Thickened gallbladder with pericholecystic fluid retention in abdominal contrast-enhanced CT scan. She was diagnosed with acute cholecystitis with perforation and underwent emergency laparoscopic cholecystectomy. Histopathology revealed infiltration of inflammatory cells along with necrosis in the gallbladder wall and amyloid deposition to the arteriolar wall that would cause arteriolar obstruction. From these findings, arteriolar obstruction due to amyloid deposition might be one of the causes of acute acalculous cholecystitis in this case. Her postoperative course was uneventful and she was discharged from our hospital on the 11^th postoperative day.
