Abstract
A 37-year-old male with metachromatic leukodystrophy, a congenital cerebroside storage disease strongly associated with benign gallbladder polyps, presented with hemobilia and acalculous cholecystitis due to a long, slender, benign gallbladder polyp. This case report extends the clinical spectrum of gallbladder polyps and demonstrates a novel cause of hemobilia. The unusually long, slender polyp shape may have promoted hemorrhage due to the potential for torsion around a slender stalk. The mechanism of cholecystitis may have been cystic duct obstruction from blood clots or possibly from prolapse by the long, slender polyp into the cystic duct.
