Physical Exam • Measure liver span • Determine liver’s contour & consistency • Is the surface smooth, irregular or nodular? • Is the edge rounded or sharp? • Is palpation painful? DO NO HARM! • Listen for bruit
Cont. P/E • Any ascites ? • Increased portal venous pressure, tissue infiltration, or reticuloendothelial cell hyperplasia • In newborns: do fundoscopy for chorioretinitis • Congenital infections • Note: skin lesions, subcutaneous nodules, lymphadenopathy, spider angiomata or stigmata of storage disease
