Abstract

Coexistence of Langerhans cell histiocytosis and ganglioneuroblastoma is rare and seldom reported in the literature. A 3-year-old girl with Langerhans cell histiocytosis underwent 18 F-FDG PET/CT imaging for staging, which demonstrated significant 18 F-FDG accumulation in the mandibles. Unexpectedly, a mild hypermetabolic soft mass was detected in the upper retroperitoneum. Results of surgical pathology of the abdominal mass were consistent with ganglioneuroblastoma.
