Presakral schwannomalar nadir görülen, genellikle asemptomatik, iyi huylu tümörlerdir. Bu olgu sunumunda, 57 yaşında erkek bir hasta kolon kanseri nedeniyle ameliyat edildikten sonra takiplerinde, presakral alanda schwannoma tespit edildi. Lezyona başlangıçta lenf nodu metastazı olarak değerlendirildi ancak cerrahi sonrası patoloji sonucu ile schwannoma tanısı konuldu. Presakral schwannomalar, genellikle Manyetik Rezonans Görüntüleme (MRG) ile daha net tanı alır, ancak tanı da BT (Bilgisayrarlı Tomografi) taramaları da kullanılır. Cerrahi tedavi, tümörün konumuna göre farklı yaklaşımlar gerektirir ve tümörün konumuna göre cerrahisi zorlu olabilir.

Presacral schwannomas are rare, usually asymptomatic, and benign tumors. In this case report, a 57-year-old male patient was found to have a presacral schwannoma during follow-up after undergoing surgery for colon cancer. Initially, the lesion was considered to be a lymph node metastasis, but histopathological examination confirmed the diagnosis of schwannoma postoperatively. Presacral schwannomas are typically more accurately diagnosed using Magnetic Resonance Imaging (MRI), although Computed Tomography (CT) scans can also be helpful in the diagnostic process. Surgical treatment requires different approaches depending on the tumor's location, and the surgery can be challenging due to the tumor's anatomical position.
