title: Epsilon amino caproic acid myopathy: additional features.
abstract: In a patient with a proximal myopathy due to Epsilon Amino Caproic Acid (EACA) bedrest led to marked improvement even before withdrawal of the drug. A biopsy showed a selective necrosis of type I fibers. Plasma level of EACA was low and plasma level of lysine was normal. A 99mTechnetium-MDP showed marked uptake in the affected muscles, whereas a 67Gallium scan was negative.
