Pott's puffy tumor: multidetector computed tomography findings.

A subperiostal abscess of the frontal bone as a complication of osteomyelitis, appearing as a puffy, indolent tumor of the forehead, was first described by Pott. This less-common complication of is known as Pott's Puffy tumor. The complications of Pott's Puffy tumor are preseptal and orbital cellulites by downward spread to the orbit and intracranial infection by posterior extension. We present a case of Pott's Puffy tumor complicated by intracranial infection imaged by means of multidetector computed tomography.
