MRCP UK EXAMINATIONS

Detailed explanation-1: -Tympanitic (drum-like) sounds produced by percussing over air filled structures. Dull sounds that occur when a solid structure (e.g. liver) or fluid (e.g. ascites) lies beneath the region being examined.

Detailed explanation-2: -Dullness is the normal sound heard when percussing tissues that are dense in consistency, such as the liver. Dullness is typically considered an abnormal sound if elicited with percussion over the lungs or the intestines, stomach, or bladder.

Detailed explanation-3: -Dullness is typically heard over fluid or solid organs such as the liver or spleen, which can be used to determine the margins of the liver and spleen. This can help with estimating the size of these organs and can help to identify organomegaly (i.e., enlarged organs).

Detailed explanation-4: -You’ll hear dull sounds over solid structures (such as the liver) and fluid-filled structures (such as a full bladder). Air-filled areas (such as the stomach) produce tympany. Dullness is a normal finding over the liver, but a large, dull area elsewhere may indicate a tumor or mass.
