Abstract [eng] We report a clinical case of an extremely rare neuroendocrine tumor of the right middle ear (MeNET) that recurred after 13 years with a local extension into the right temporal fossa. In the current medical literature, there are approximately 150 cases of MeNETs and even fewer cases with more than 10 years of follow-up, recurrence, and intracranial tumor progression. Therefore, we believe that this paper can make an important contribution to the existing and future knowledge about this disease. The purpose of this article is to present our experience in treating such a rare neoplasm in a 35-year-old woman. The patient initially complained of worsening hearing in her right ear over the past year. The final diagnosis was made based on the findings of computed tomography (CT), magnetic resonance imaging (MRI), and histological and immunohistochemical evaluation of excisional biopsies of the original and recurrent tumors. The primary tumor masses were removed with clear resection margins, and the ossicular chain was reconstructed. The patient has been monitored clinically and radiologically with temporal bone CTs every year and MRIs three times in general since then. A postoperative audiogram showed remaining mixed hearing loss in the right ear that eventually worsened as the tumor grew. Tumor recurrence and progression after 156 months (13 years) were seen on CT and MRI, requiring further treatment. After resection of the recurrent tumor, paresis of the right facial nerve developed, which was treated with dexamethasone. The surgical treatment caused the initial symptoms to disappear, but the facial nerve paresis persisted with mild functional improvement. The patient is not receiving adjuvant radiotherapy and is being monitored closely because the tumor may recur in the future.
