“…32 Outgrowth from the posterior fossa is critical to note, and extension of giant tumors around the tentorium may indicate the need to resect a portion of the tentorium for adequate tumor exposure and microdissection. Beyond the local anatomical relationships of the tumor, its intrinsic characteristics such as a cystic component can be identified, which has been correlated with poorer outcomes.…”

“…Tamamen intrakanaliküler olan schwannomlar yuvarlak veya oval olup, konveks medial kenarları vardır. Akustik kanal dışındaki komponenti genellikle küre şeklinde olup huni şeklindeki intrakanaliküler komponenti ile birlikte "dondurma külahına" benzetilir (Resim 17) [88]. Serebellar flokkulus, foramen Luschka'daki koroid pleksus gibi normal yapılar serebellopontin açı (SPA) lezyonları ile karıştırılmamalıdır.…”

“…Eğer tümör 2 cm'den küçük ise veya eşlik eden başka hastalıklar varsa yaş-lılarda görüntüleme ile takip edilebilir [99]. Genellikle önerilen ilk görüntüleme takibini 6. ayda yapıp sonra yıllık kontrollere geçil-mesi ve 5 yıl takip edilmesi yönündedir [88]. Amerikan Otolaringoloji Baş Boyun Cerrahisi Akademisi'ne göre SPA sisterni (ekstrameatal) tümörünün ölçümü petröz temporal kemiğin posterior yüzeyine paralel alınan maksimum anteroposterior uzunluk ile buna dik mediolateral uzunluk alınarak yapılmalı ve kaydedilmelidir [100].…”

“…Vestibular schwannomas, or acoustic neuromas, arise from the Schwann cells surrounding the eighth cranial nerve, resulting in both hearing loss and tinnitus as well as vertigo and disturbances in balance 41 . Patients with a strong suspicion for acoustic neuroma should undergo contrast-enhanced imaging to both make a diagnosis as well as to monitor the growth of the tumor, which tends to be slow 42 . The surgical resection of acoustic neuromas may also result in hearing loss and tinnitus from direct damage to the auditory nerve 43 .…”
