"This 92

year-old male patient presented for assessment of acute hemiparesis. An incidental finding was marked thickening of the calvarium. The diploic space is widened and there are ill-defined sclerotic and lucent areas throughout. The cortex is thickened and irregular. The findings probably correspond to the “cotton wool spots” seen on plain films in the later stages of Paget’s disease." (dr Dawes)

Imaging of

skull vault tumors in adults. Miscellany. Paget disease (a, b) CT (a) and X-ray (b): Characteristic mixed bone lysis and sclerosis, cortical bone thickening, and expansion. Osteoporosis circumscripta cranii CT (c, d): large geographic radiolucent areas involving medullar and cortical bone in frontal and occipital regions (arrows). Amyloidoma (e, f) CT (e) and T2WI (f): Giant heterogeneous mass with marked T2 hypointensity and calcifications. Renal osteodystrophy CT (g): shows characteristic “salt-and-pepper pattern.” Brown tumor (h, i): unspecific well-defined, cystic appearance (arrows). Thalassemia CT (j): Diffuse diploic widening and “hair-on-end” appearance (arrow) with characteristic occipital bone preservation (arrowhead). Bone sarcoidosis (k, l) CT (k) and T2WI (l): Mixed predominantly lytic multiple lesions with lace-like internal pattern of calcification and T2 hypointensity (dashed arrows). Osteitis CT (m, n): Bone focal lysis and erosions of osteitis (arrows) contiguous to a frontal sinusitis complicated with intracranial laminar abscess (dashed arrow)
