Mycobacterium genavense specific mesenteritic syndrome in HIV-infected patients: a new entity of retractile mesenteritis?

Abdominal mesenteritis is a rare and poorly understood gastroenterological disease. Here, we report on two identical cases of Mycobacterium genavense associated retractile mesenteritis in HIV-positive patients.
