Fig. 2C —3-year-old girl with palpable scalp soft-tissue mass. Axial
MR images of brain show well-circumscribed calvarial lesion (arrows),
which is isointense on T1 (A), enhances almost homogeneously after
gadolinium administration (B), and is hyperintense on T2 (C).
Arrowhead in C denotes dense sclerotic central focus, which corresponds
to button sequestrum found on CT scan (not shown). Note generalized brain
atrophy, which is associated finding in Langerhans cell histiocytosis.
