Acute acalculous cholecystitis complicating an imported case of mixed malaria caused by Plasmodium falciparum and Plasmodium vivax.

A 40-year-old man was admitted with a 6-day history of fever and abdominal pain. His right upper quadrant was tender on palpation. A blood smear revealed trophozoite forms of Plasmodium vivax and Plasmodium falciparum. Abdominal ultrasound findings were consistent with acute acalculous cholecystitis. He was treated successfully with quinine and doxycycline and discharged in good clinical condition.
