Objectives: Sporadic endolymphatic sac tumor (ELST) is rare. The purpose of this study was to analyze the clinical feature and surgical outcome of a single-center series of sporadic ELSTs. Patients and Methods: We retrospectively reviewed all cases of sporadic ELSTs operated at the Tiantan hospital between 2010 and 2020. Results: Retrospective record revealed 14 patients with sporadic ELSTs who underwent surgical management. Serum VEGF(vascular endothelial growth factor)values of 6 patients were measured on admission, and the levels were all higher than normal(0 -160 ng/L, Enzyme-Linked ImmunoSorbent Assay). All patients underwent surgical treatments, and there was no significant difference in KPS before and after the operation(KPS = 88:88). The average maximum diameter of the tumor was 41 mm (range28 - 56 mm). After surgery, Two patients received radiation therapy, We did not encounter any case with metastatic dissemination. No deaths occurred during follow-up. Conclusion: ELST is defined as an aggressive or low-grade malignant tumor, with the characteristics of local recurrence and invasion of bone growth. Sporadic cases are common, and this rare tumor provides insight into the relationship between ELST and VHL syndrome. Early surgical resection can prevent or reduce the disability of auditory vestibular symptoms, and improve the chance of complete resection and retention of hearing. As far as possible complete resection of the tumor can prolong the disease-free survival of patients. Preoperative radiotherapy or stereotactic therapy cannot control tumor growth. Postoperative radiotherapy may have a positive effect on tumor control. The high expression of VEGF in patients may be related to tumor occurrence and development.
