Adult eosinophilic granuloma of the lumbar spine with atypical dissemination. Case report: a long-term follow-up.

Vertebral Eosinophilic Granuloma (EG) is a frequently reported disease, but further dissemination rarely occurs when the initial lesion is in the lumbar region. We present a case of EG, initially located in L5 vertebra, which disseminated to the skeletal bones and pulmonary system months after total excision in an adult.
