Abnormalities of the Skull and Facial Bones
Cause
                           Radiological Features
Enlargement of Skull Vault
                Children
Hydrocephalus
Sutural  diastasis, increased convoluted
markings, “copper beaten skull
Raised intra cranial pressure
Bulging of fontanelle in infancy.
                Adults
Acromegaly
Enlarged frontal sinuses and mandible, erosion
and enlargement of sella turcica
Paget’s disease
Thickened skull vault, increased density of vault
and facial bones.
Increased Density
                Localised
Hyperostosis frontalis
Symmetrical thickening of the inner table of
skull vault, usually in women, of no significance.
Meningioma
Area of  localised sclerosis, possible enlarged
groove of feeding artery.
Fibrous displasia
Asymmetrical, affecting the facial bones maxilla
and base of skull.
               Generalised
Paget’s disease
Irregular sclerosis with thickened vault.
Secondary deposits. e.g. prostate & breast
Irregular sclerosis, thickened vault.
Lytic lesions
                Childhood
Secondary deposits, neuroblastoma, leukaemi
Variable appearances,  Sutural deposits may
mimic sutural diastasis.
Eosinic granuloma, Histiocytosis X
Transradient defect with bevelled edges.
                 Adults
Myelomatosis
Rounded translucent (2-10mm) multiple ‘holes’
Secondary deposits
Generally ill defined translucent patches.
Hyperparathyroidism
Mottled appearance of ‘pepper pot’ skull.
Paget’s
Sharply defined zones affecting large areas of
the vault.
