Trauma in the Pagetoid: beware the non-specific scintigram.

Radionuclide brain scans and cerebral blood flow studies have become highly sensitive but they remain quite nonspecific diagnostic modalities. Previous reports have discussed similarities between Paget's disease of bone and subdural hematoma on radionuclide studies. We encountered a case in which Paget's disease produced all the described manifestations of subdural hematoma. The differential features of the two conditions and their pathophysiological bases are discussed.
