Q: During auscultation of an acute abdomen, the sound of friction rub on the left side of the abdomen raises the possibility of which disease process?
Answer: Splenic infarct
Friction rub in splenic infarct is due to the sliding of peritoneal layers over the infarcted splenic area. This is not an exclusive sign and should be considered with other clinical and laboratory clues pointing towards splenic pathology.
