Case reports published on gastroenterology, hepatology topics

Reports on purple urine in a patient with chronic constipation, long-term use of metronidazole mimicking hepatic encephalopathy, and chronic lymphocytic leukemia involving the liver were published in the past month.

Two image/video cases and one case report on gastroenterology and hepatology topics were published in the past month by Annals of Internal Medicine: Clinical Cases.

One image/video case described a 72-year-old man with paraplegia and chronic constipation who presented with deep purple urine in both his nephrostomy and urostomy bags on admission, while the other presented the diagnosis of metronidazole-induced encephalopathy in a 66-year-old man with a history of cirrhosis. The case report described an atypical presentation of chronic lymphocytic leukemia in a patient who presented with rising liver enzyme levels, extensive hepatic infiltration, and portal hypertension but no evidence of high-grade transformation on liver biopsy. All were published Sept. 6.
