An isotope-diagnostic approach to Erdheim-Chester's disease of the heart.

Erdheim-Chester's disease is a form of histiocytic granulomatosis afflicting the skeletal system and various inner organs. Apart from incidental findings of involvement of various structures and tissues, a complete diagnostic workup to evaluate afflicted bodily parts is not known. The authors we present several specific isotope-diagnostic techniques of a case to support the identification of this rare multisystem infiltrative disease.
