ANSWER
The correct diagnosis is eosinophilic granuloma, of
which this "punched out" lesion with beveled edges and
lack of bony reaction is typical. The calvarial lesion
is usually confined to the bone but may extend intracranially.
In the skull, it is often a solitary lesion but may
be part of a larger picture of histiocytosis.
