“…Our assumption was based on the location of the tumour, extending more superiorly than tympanojugular paragangliomas typically do. However, endolymphatic sac tumours are usually centred at the level of the posterior semicircular canal and generally spare jugular foramen [17]. In our first case, the tumour centred at the jugular foramen and from there extended superiorly to erode the posterior semicircular canal.…”

Low-grade fibromyxoid sarcoma (LGFMS) is a rare slow-growing malignant tumour with a deceptively benign histologic appearance. Herein, we report two cases of LGFMS with variable clinical presentations. The first case was a 17-year-old female who referred to our department due to deaf ear on the right together with ipsilateral gag reflex impairment and globus sensation in the pharynx. The second case was a 35-year-old female with recurrent LGFMS, suffering from headaches, vertigo, and episodes of loss of consciousness. LGFMS of the temporal bone is a rare pathology, and to the best of our knowledge, no such cases have been reported before.

Highlights Endolymphatic Sac tumors are very rare type of tumor reported in practice of Neurosurgery or ENT. This tumor may present in sporadic fashion or as a part of Von Hippel Lindau disease. In this case report Endolymphatic Sac Tumor of sporadic type is presented at the cerebellopontine angle in the posterior fossa of the skull. It was managed in our facility with multidisciplinary approach. The clinical presentation, investigations and management of the patient are discussed in details and a brief review of the literature has been performed.

“…У пациентов с ОЭМ часто наблюдаются сенсоневральная потеря слуха и шум в ухе, реже оталгия, головокружение, атаксия, нейропатия лицевого нерва, оторея, которые прогрессируют постепенно [48,76]. По мере прогрессирования опухоли пациенты могут испытывать головокружение, атаксию, поражение тройничного, лицевого и преддверно-улиткового нервов, боль, шум в ухе [1]. Парез или паралич лицевого нерва наблюдается в случаях распространения опухоли до канала лицевого нерва и поражения самого нерва.…”

“…Опухоль эндолимфатического мешка (ОЭМ) -редкая, медленно растущая, но агрессивная опухоль. Первое описание ОЭМ появилось в литературе в 1989 г. Это было эпителиальное новообразование, которое, по предположению автора, возникло в эндолимфатическом мешке (ЭМ) и было обозначено как аденокарцинома [1]. Новообразование в начальной стадии расположено на задней поверхности каменистой части височной кости и медиальнее, может вовлекать в патологический процесс твердую мозговую оболочку [2].…”

Endolymphatic sac tumor: rewiev of literature

Endolymphatic sac tumors are rare neoplasms of the temporal bone, histologically benign, but clinically behaves as malignant tumors causing destruction of surrounding tissues. The tumor originates from the posterior surface of petrous part of temporal bone, where endolymphatic sac is situated anatomically. The tumor causes destruction of the posterior surface of the petrous part of the temporal bone, inner ear, mastoid process, etc. Endolymphatic sac tumor can be both sporadically and in patients with von Hippel – Lindau disease. Due to the rarity of this tumor, it is easy to confuse it with other tumors, such as paraganglioma, middle ear adenoma, adenocarcinoma, papillary thyroid carcinoma or papilloma of the vascular plexus. Computed tomography (CT) and magnetic resonance imaging (MRI) are of great diagnostic importance and play an important role in planning treatment tactics. The optimal method of treatment is resection of pathologically altered tissues. In some cases (incomplete resection of tumor, the patients with concomitant diseases or inoperable cases) receive courses of X-ray or radiosurgery. If a tumor is detected in the early stages, the volume of resection can be minimized while preserving hearing and vestibular function of the inner ear. Recurrence usually happens due to difficulty to identify the extension of the tumor. Diagnosis and correct preoperative planning, with embolization if it possible, will facilitate surgery and avoid subtotal tumor resection due to intraoperative bleeding. Long follow-up period is important in order to avoid recurrences. Insufficient coverage of this problem in the literature is associated with a low percentage of its occurrence in otosurgical practice, which complicates the timely diagnosis and treatment of this type of tumors of the temporal bone, worsens the prognosis.
