Endolymphatic sac tumors (ELST) are rare neuroectodermal neoplasms arising from the epithelium of the endolymphatic sac or duct. Despite their benign histopathological features, ELSTs frequently demonstrate a locally destructive growth pattern with involvement of the skull base and cranial nerves. While ELSTs may arise sporadically, the majority of cases occur in association with Von Hippel-Lindau (VHL) syndrome. ELSTs are commonly diagnosed late due to their slow growing nature and non-specific symptomatology. Surgical resection is the treatment of choice. However, due to the location of these tumors in the lateral skull base surgical intervention carries a high risk of injury to critical neurovascular structures in close proximity. We presented the case of a 51 years old gentleman with a three-months history of hearing loss and otalgia. He subsequently developed multiple cranial neuropathies and was diagnosed with a sporadic ELST. He underwent a complete surgical resection and received adjuvant radiotherapy.
