Intralesional glucocorticoid treatment of an isolated intracranial juvenile xanthogranuloma: a case report.

Juvenile xanthogranuloma is a type of non-Langerhans cell histiocytic process that appears primarily in children and is described as a benign lesion. Although they typically present as a cutaneous lesion, it can also present in other areas including within the central nervous system. We report a 6-month-old infant who presented with seizure-like activity who was found to have a single intracranial mass within the right temporal area on magnetic resonance imaging of the head. The mass was biopsied and pathologically identified as a juvenile xanthogranuloma. In order to avoid the morbidity associated with a gross total resection, an intralesional steroid injection was utilized for treatment which our patient tolerated well. Intralesional steroid injection for the treatment of a symptomatic isolated intracranial juvenile xanthogranuloma has not been described but was successful for our patient.
