Diarrhea and gallbladder hydrops in an immunocompetent child with Cryptosporidium infection.

We report a case of an immunocompetent child who developed gallbladder hydrops during a concurrent diarrheal illness caused by Cryptosporidium parvum. Hepatobiliary disease and chronic cryptosporidial diarrhea is an accepted association in adults with HIV infection but has only once previously been reported in a child, also with HIV.
