The operculum syndrome.
A 48-year-old man presented with signs of pseudobulbar palsy. On computed tomography (CT) he was found to have extensive tissue loss in the region of the sylvian fissure and insula bilaterally. This appearance on CT represents the radiological correlate to anatomic descriptions of the operculum syndrome, and is useful in distinguishing the condition from pseudobulbar palsy.
