Biliary cryptosporidiosis in a patient without HIV infection: endosonographic, cholangiographic, and histologic features (with video).

摘要

A 62-year-old man with long-standing chronic lympho-cytic leukemia (CLL) and hypoglobulinemia presented at our institution for evaluation of intractable diarrhea for 6 months. His diarrhea was complicated by dehydration requiring repeated hospitalizations, malnutrition with 30-pound weight loss, and anorexia. He was receiving total parenteral nutrition for maintenance of hydration. On previous evaluation, his diarrhea was attributed to cryptosporidiosis, diagnosed by a small-bowel biopsy, which had been refractory to treatments with azithromy-cin, paromomycin, and nitazoxanide. There was no history of jaundice.
