title: [Fever of unknown origin].
abstract: A 54-year-old man suffered from intermittent episodes of high fever up to 40 degrees C for a period of about 2 years. In 1945 he was wounded by a shell fragment entering the left lower thorax. Finally the combination of diagnostic procedures revealed the origin of the fever. A colonic fistula leading to the shell fragment in the spleen was found.
