Keywords:Typhoid fever, ultrasonogram, bowel wall thickening, mesenteric lymphadenopathy
Objectives: To See the use of abdominal ultrasonogrphic in the diagnosis of Typhoid fever.
Materials and Methods: This cross sectional study on enteric fever was carried out during the period of July 2008 to June 2009 on 30 patients between 2 months 12 years of age of either sex admitted with the clinical diagnosis of enteric fever having positive hemoculture for Salmonella typhi or paratyphi and or significant Widal test.
