A juvenile xanthogranuloma (zan tho grahn you LOH mah), or JXG, is a benign skin lump or bump caused by a collection of cells called histiocytes. These may be red, orange, or tan at first, but over time may become more yellow in color. These bumps usually appear on the head, neck, and trunk.
A 6-month-old infant who presented with seizure-like activity 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 the patient 1).
