A case of bipolar disorder and typhoid fever.

Many medical disorders presentwith psychiatric symptoms. Teasing out what is caused by the medical problem and what is underlying psychopathology can be a tremendous challenge. We report the case of a young man with no documented past psychiatric history that developed symptoms consistent with bipolar disorder with mood-congruent psychotic features as well as typhoid fever. In this report, we summarize the biological, psychological, and social underpinnings of this rare and interesting case.
