Abstract
An isolated eosinophilic granuloma involving the posterior elements of a lumbar vertebra is reported in a 3-year-old boy presenting with progressive limp. Radiological investigations revealed osteolysis of the L5 right pedicle. MRI showed a well-defined homogeneous mass with nonspecific signal intensity. An unusual feature was the paravertebral muscular location of the largest part of the tumour indicating a possible soft tissue origin. Immunohistochemical studies were typical for Langerhans' cell histiocytosis.
Conclusion A limp can be due to lumbar and paravertebral muscular location of Langerhans' cell histiocytosis.
