Bone window reveals complete opacification of the right mastoid air cells, extending into the middle ear and to the petrous apex. Notably, there is evidence of bone erosion, indicative of osteomyelitis affecting the petrous apex (petrous apicitis) and erosions of the lateral wall of the mastoid in the right temporal bone.
A large peripheral enhancing collection is identified in the right temporal fossa. This collection, situated adjacent to a dehiscent erosion of the temporal bone, is highly suggestive of a subperiosteal abscess. Remarkably, the abscess extends into the right masseter muscle, contributing to the overall complexity of the case.
No cerebral abscess or sinus thrombosis.
Bilateral anterior frontal and temporal lobes areas of encephalomalacia.
