Magnetic resonance imaging of nalbuphine-induced myocutaneous sclerosis.

Myocutaneous sclerosis is a known complication of intramuscular and subcutaneous injection of narcotics. We have described the MRI findings of this entity with superimposed infection in a patient addicted to intramuscular and subcutaneously administered nalbuphine. The clinical and imaging features of this disorder are sufficiently characteristic to allow confident diagnosis. This is the first report of this disorder due to nalbuphine.
