Q: Osler's nodes are hallmark of infective endocarditis (IE). But they can be found with which ICU related procedure?


Answer: Infected arterial lines

This is true that Osler's nodes are considered as one of the hallmark of IE but they can be seen in other conditions such as Systemic Lupus Erythematosus(SLE), Marantic endocarditis and Disseminated gonococcal infection. In ICU if  arterial catheters get infected, Osler's node may be seen distal to them. They have been found mostly associated with infected radial lines.
