Metameric pruritus as the sole manifestation of an intramedullary tumor in a toddler.

An 18-month-old child presented with persistent pruritus and excoriation involving the right T9 and T10 dermatomes. She did not exhibit any other dermatological or neurological anomalies. Based on magnetic resonance imaging investigation of the spine, T8 ganglioglioma was diagnosed and surgically removed resulting in resolution of the pruritus within a few days.
