[Septate gallbladder and acute cholecystitis in a four-year-old girl (author's transl)]. / Vesícula tabicada y colecistitis aguda en una niña de cuatro años.

A case of a four year old girl, first seen at the emergency ward for an abdominal pain, is reported. Exploration revealed a mass at the right hypochondrium which a laparotomy labeled as a dropsy gallbladder with a complete transversal septum at the union of the gallbladder's body and infundibulum. Microscopic examination showed an acute cholecystitis. A classification of septate gallbladders is performed and embryology revised. Microphotographs of human embryo are presented making etiopathogenesis of this case understandable. The scanty bibliography on this topic makes this case extremely rare.
