“…Lunardi et al documented a case featuring cerebellar syndrome and neurological symptoms 5 . House and Brackmann witnessed the destruction of the petrous apex, indicating a possibly severe and progressed state of cerebellopontine angle cholesterol granuloma 6 . CT scans reveal cholesterol granulomas as distinct, non-enhancing, expanding masses accompanied by bone weakening and erosion 7,8,9 .…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…These include suboccipital, infracochlear, infralabyrinthine, middle fossa, translabyrinthine, transotic, infratemporal, and endoscopic endonasal approaches. 4,7,[9][10][11][12][13][14]16,20 The transsphenoidal endoscopic approach is less invasive than the lateral open approaches, as it does not require brain retraction and preserves facial nerve and hearing function. To this end, endoscopic endonasal procedures are indicated in cases in which lesions of the petrous apex abut the posterior wall of the sphenoid sinus.…”

“…House and Brackmann were the first to describe involvement of the petrous apex in 1982 (11). Further reports indicated that cholesterol granulomas account for 60% of petrous apex lesions (2).…”
