Figure 13. A 9-year-old girl came with anorexia and weight loss. Painful swellings on the forehead, chest wall and palm were noticed over a period of 2 months. A section through the upper thorax shows large, encapsulated low attenuation collections in the chest wall, encircling the upper half of the sternum contiguous with necrotic superior mediastinal lymph nodes. The sternum and the costochondral junctions mainly on the left side appear eroded. A pre-vertebral abscess with epidural extension at the mid-dorsal level was not associated with a neurological deficit.
