Abstract

Background.- Endolymphatic sac tumors are rare intracranial tumors originating from temporal bone of the endolymphatic sac. They are histologically nonaggressive lesions, but often become locally invasive. We report one patient with pathologically proven endolymphatic sac tumor. A 45-year-old woman admitted a 7-year history of progressive right-sided hearing loss and recent onset of localized right ear pain. Magnetic resonance imaging showed a solid, heterogeneous enhancing mass in the petrous portion of the temporal bone resembling glomus jugulare tumor. The patient underwent a combined presigmoid and retrosigmoid approach to the tumor and partially resected. Observations.- She remained neurologically stable and underwent gamma-knife radiosurgery for residual and recurrent tumor after follow-up of 9 months. It is indispensable to differentiate between endolymphatic sac tumors and other pathologies, since requires to a different surgical strategies. Endolymphatic sac tumor invades the petrous bone and surrounds the neurovascular structures extending intracranially. A complete radical resection without neurological deficits is impossible in advanced cases. The role of adjuvant therapy is controversial and open to development. Because of this case, we reviewed the literature on endolymphatic sac tumors in changing concept.

Özet

Endolenfatik kese tümörleri temporal kemiğin endolenfatik kesesinden kaynaklanan nadir intrakranial tümörlerdir. Histolojik olarak agressif olmamalarına karşılık, sıklıkla lokal invazyon yaparlar. Patolojik olarak endolenfatik kese tümörü olarak rapor edilmiş bir hastayı bildiriyoruz. Kırkbeş yaşında kadın hasta, 7 yıldır giderek ilerleyen sağ kulakta işitme kaybı ve yeni eklenmiş sağ kulak ağrısı ile yatırıldı. Manyetik rezonans görüntülemede glomus jugulare tümörüne benzeyen, temporal kemiğin petroz kısmında yerleşmiş, heterojen kontrast turan solid bir kitle ile karşılaşıldı. Hasta kombine presigmoid ve retrosigmoid yaklaşımla opere edildi ve tümör kısmi olarak çıkartıldı. Hasta operasyon sonrası nörolojik olarak stabil kaldı. Dokuz ay takip sonrası residüel ve nüks tümör nedeni ile gamma-knife tedavisi aldı. Endolenfatik kese tümörleri ile diğer patolojiler arasında ayrım yapmak, farklı cerrahi stratejiler gerektirdiğinden önemlidir. Endolenfatik kese tümörleri petroz kemiği invaze eder ve intrakranial olarak ilerleyip nörovasküler yapıları çevreler. Nörolojik defisit yaratmadan tam bir radikal rezeksiyon yapmak ilerlemiş olgularda mümkün değildir. Adjuvan tedavinin rolü tartışmalıdır ve gelişmeye açıktır. Bu olgu nedeniyle, değişen anlayış içinde endolenfatik kese tümörlerinde literatürü gözden geçirdik.
