A 31 year-old woman with long-standing type 1 diabetes mellitus (DM) and prior cholecystectomy was referred for evaluation of persistent, abnormal liver function tests (LFTs) and recurrent acute pancreatitis. There was no prior history of heavy alcohol intake. She was hospitalized 6 weeks prior with nausea, vomiting and abdominal pain. Laboratory parameters revealed alanine

After resolution of her acute illness, LFTs normalized. Four weeks later she was re-admitted for acute pancreatitis and DKA. ALT was 268 U/L, AST 344 U/L, ALP 289

U/L, and total bilirubin 1.8 mg/dL. Repeat CT revealed diffuse pancreatic stranding and inflammation, consistent with acute pancreatitis. LFTs again normalized after treatment of DKA and pancreatitis. At presentation to our center, she complained of diffuse abdominal pain. Physical examination, vital signs and body mass index were within normal limits. ALT was 185 U/L, AST 627 U/L, ALP 280 U/L and total bilirubin 0.7 mg/dL.

pancreatitis and abnormal LFTs showed hyperechoic strands and lobularity in the pancreatic parenchyma (Figure 1A). There was no evidence of pathology within the bile duct and no evidence of pancreatic or biliary ductal dilatation or evidence of pancreas divisum. A homogeneous, abnormal echotexture was seen in the left lobe of the liver. EUS-guided liver biopsy with a core needle (Olympus

Glycogenic hepatopathy, a rare and unique condition, is seen in patients with poorly controlled DM where glycogen deposits heavily within hepatocytes.1 Patients may be asymptomatic or present with symptoms of acute DKA such as nausea, vomiting and abdominal pain. On physical exam, hepatomegaly is typically present. LFTs can be elevated up to 10X upper limits of normal. Lactic acid can also be elevated. It is difficult to clinically differentiate from non-alcoholic steatohepatitis (NASH) since both commonly cause hepatomegaly and elevated LFTs; therefore liver biopsy is useful to establish a diagnosis. This is the first case of glycogenic hepatopathy discovered using EUS-guided liver biopsy. The characteristic histologic changes seen include abundant cytoplasmic glycogen deposits within hepatocytes on PAS (Figure 1C). Hepatocytes become “ghost cells” upon diastase digestion of the

glycogen (Figure 1D).1 Similar findings are seen in glycogen storage diseases, which should be excluded clinically. Tight glycemic control is the mainstay of therapy which results in complete resolution of symptoms and laboratory abnormalities.2 Our patient had associated recurrent pancreatitis, although its relationship to hepatopathy is unclear. With adjustment of her insulin regimen and improved
