The latter represents a collection of blood between the pericranium and skull and has been described as a "banal unexciting bulge on the skull of the newborn to which the examiner pays but scant attention".1 X-rays of the skull2 in the latter group may reveal a linear or depressed fracture and, occasionally, symptoms of a subdural hematoma may develop.

Further hematologic studies of such patients are seldom recommended unless there is evidence of
