Komplikationen bei Mastoiditis

School ager

with pus draining from the right ear. Axial CT with contrast of the brain with bone windows (left) shows opacification and destruction of the right mastoid air cells while axial CT with contrast of the brain with soft tissue windows (right) shows a large low density ring enhancing lesion in the right cerebral hemisphere that is causing midline shift to the left.The diagnosis was right coalescent mastoiditis with an intracranial abscess.

Infant with

left otitis media and left neck swelling. Axial and coronal CT with contrast of the neck with soft tissue windows (above) show extensive left cervical adenopathy and inflammation. Axial CT with contrast of the neck with bone windows (below) show bilateral complete opacification of the mastoid air cells and subtle erosive changes in the anterior aspect of the left temporal bone. There were no intracranial findings.The diagnosis was left coalescent mastoiditis.
