A 27-year-old manpresented with an 8 months’ history of back pain radiating to his leg. Imagingrevealed an expansile lytic lesion in the body of the first sacral vertebra(S1) (Figs. 1-7). CT-guided biopsy was subsequently performed (Fig. 8), andhistology confirmed the lesion to be Langerhans cell histiocytosis.aab影像园XCTMR.com
