Abstract
Background Endolymphatic sac tumor (ELST) is one of neuroectodermal tumor which arising from endolymphatic sac and duct. It is actually quite rare, with less than 200 cases reported. Although ELST presents benign appearance in histopathology, it can present aggressive destructive behavior in clinical. The cornerstone of treatment for ELST is complete surgical excision. However, it is almost impossible to completely resect the advanced stage tumor. There is still controversy about other treatments, such as radiotherapy and gamma knife surgery. Case presentation A 47-year-old man was admitted in The First Affiliated Hospital of Fujian Medical University with a 7-year history of progressive hearing loss and near 6-month repeated attacks of headache. Preoperative CT revealed a massive intracranial lesion and associated hydrocephalus. MR scanning demonstrated a 7.2 cm × 4.6 cm × 4.2 cm bulky mass located in left-sided posterior cranial fossa and temporo-occipital region which showed hyperintensity on T1-weighted images and mixed signal intensity on T2-weighted images. There was no neither clinical manifestation nor family history of Von Hippel–Lindau syndrome (VHL).Due to the mass that was large and invading the bone of skull base, it was difficult to extirpate surgically, so the ventriculoperitoneal shunt combined with local biopsy was performed. The postoperative pathology and immunohistochemical findings confirmed the lesion was an endolymphatic sac tumor. After operation, the patient regularly received radiotherapy. Conclusion The widely accepted management of ELST is complete surgical resection. However, it is difficult for surgeons to achieve radical resection with late-stage ELST. Currently, there is much dispute about the role of radiotherapy for the management of ELST in academic circles. In this case where the mass cannot be surgical removed, radiotherapy has the curative effect for ELST in terms of disease control and quality of life.

Abstract
Patients with intractable vertigo often present a diagnostic dilemma to the treating physician. A wide spectrum of diseases, ranging from those of the labyrinth onto the central nervous system, may present predominantly with vertigo. In some cases, it requires the clinical acumen of an experienced neuro-otologist, to decipher these vertiginous symptoms and arrive at a definitive diagnosis. Meniere's syndrome is one such phenomenon, where the endolymphatic hydrops may be attributable to varied aetiology. We report a case of sporadic (non-syndromic) Endolymphatic Sac Tumor which presented to us, mimicking a classical Meniere's syndrome. We discuss its clinical presentation, diagnostic modalities, operative technique and histo-pathological features. The case is reported along with a review of the world literature on this tumor, highlighting the diagnostic and management protocols advocated for this rare entity. Endolymphatic sac tumor is a rare entity which may masquerade as a classical case of Meniere's syndrome, wherein the triad of symptoms (as in endolymphatic hydrops) may not be alleviated by the usual treatment protocols. Tracing the aetiology of these symptoms, remains the most crucial factor in treating such patients.

Abstract
Endolymphatic sac tumor (ELST) is a rare lesion of the skull base for which the origin has recently been ascertained. The endolymphatic sac is derived from neuroectoderm and is located subjacent to the posteromedial surface of the temporal bone. Patients characteristically present with hearing loss, tinnitus, and vertigo; facial nerve paralysis occurs less commonly. An indolent clinical course and long-standing symptom history is typical. Endolymphatic sac tumors are known to occur more frequently in patients with von Hippel-Lindau disease, but this is not a prerequisite for diagnosis because sporadic occurrence is common. Morphologically, all of the ELSTs showed a papillary and glandular architecture. The papillary and glandular structures were lined by a single layer of flattened cuboidal-to-columnar cells that were variably ciliated. Surgery is the treatment of choice for small ELST. Remission may last for years, but local recurrence after surgery, likely secondary to incomplete resection, can occur. Radiotherapy has a 50% cure rate with large or residual tumors. Endolymphatic sac tumor is a rare tumor that can easily be confused with other papillary lesions on histopathologic grounds, with significant treatment implications. Precise preoperative anatomic localization and computed tomography and magnetic resonance imaging feature interpretation play a paramount role in achieving an accurate final diagnosis.

Abstract
In endolymphatic sac tumors associated with von Hippel-Lindau disease, early detection and surgery have been warranted to avoid associated neurological morbidity. However, in lately discovered tumors, hearing preserving surgery is often impossible and timing of surgical resection is difficult to define. We report two cases of tumors revealed by a sudden and profound hearing loss and managed conservatively for more than 15 years without worsening of the neurological symptoms associated with the endolymphatic sac tumor. Tumor size remained stable for the first patient and a stuttering growth pattern was observed for the second patient. Initial observation may be considered a not unreasonable management paradigm in these cases.

Abstract
OBJECTIVE We describe a case of endolymphatic sac tumour confined to the middle ear, which radiologically mimicked a glomus tympanicum, in a 58-year-old woman with tinnitus. CASE REPORT A 58-year-old woman presented with a one-year history of right-sided tinnitus. The clinical, radiological and surgical features were felt to be in keeping with a glomus tympanicum. However, the histopathological picture was that of a low grade papillary carcinoma of the endolymphatic sac, i.e. an endolymphatic sac tumour. CONCLUSION Endolymphatic sac tumours are classically locally aggressive and centred around the petrous temporal bone. Further growth results in complete replacement of the mastoid and petrous pyramid by tumour. To the best of our knowledge, there have been no previous reports of an endolymphatic sac tumour located solely within the hypo- and epitympanum of the middle ear.

Abstract
CONCLUSION Endolymphatic sac tumors (ELSTs) are locally invasive, osteolytic, and hypervascular tumors. If the labyrinth has not been invaded, the hearing should be preserved in operation. OBJECTIVE To summarize three cases of ELST and discuss whether to keep hearing in the surgical treatment of ELST. SUBJECTS AND METHODS Complete otorhinolaryngological examinations with audiologic, vestibular, and neurologic evaluations were performed. CT and MRI scans were carried out before operation and in the course of follow-up. The patients underwent radical removal of the tumor through a transmastoid approach and accepted postoperative radiotherapy. In two of them, the structure of the labyrinth and facial nerve were preserved in operation. RESULTS Histopathologic examinations agreed with features of an ELST. Patients suffered transitory vertigo shortly after operation, and so far, they are alive and well without further cranial nerve involvement. Case 3 patient has good hearing and facial nerve function now. No residual or recurrent tumor was detected on the postoperative MRI images.

Abstract
BACKGROUND Endolymphatic sac is an established source of low-grade neoplasms, posing a difficult problem in local tumor control. CASE DESCRIPTION Two cases of endolymphatic sac tumors are described in detail with regard to their clinical presentation and radiological findings. Both cases had diametrically opposite clinical outcomes in spite of repeated surgical interventions. A case with severe paraneoplastic syndrome and death after "cancer cachexia" is described. CONCLUSIONS Although endolymphatic tumors are known for their low-grade aggressiveness, in occasional cases, they may behave in a highly malignant behavior. The present communication highlights the contrast in clinical outcome and makes the clinician cautious of this special subgroup of tumors with a highly aggressive nature.

Abstract
Endolymphatic sac papillary tumor (endolymphatic sac adenoma, temporal-mastoid bone adenoma or adenocarcinoma, low-grade adenocarcinoma of potential endolymphatic sac origin, aggressive papillary tumor of the temporal bone, Heffner's tumor) is a rare lesion that involves the temporal bone. This tumor usually appears alone, but in 11-30% of afflicted individuals, it is accompanied by von Hippel-Lindau disease. Endolymphatic sac papillary tumors are destructive tumors that exhibit locally aggressive behavior. They slowly grow into the posteromedial section of petrous temporal bone. The main symptoms produced by these lesions include hearing loss and cranial nerve deficits. Endolymphatic sac papillary tumors develop in two principal patterns that histopathologically form follicular and papillary or solid structures. Those two patterns are usually manifested in the same tumor. Immunochemical analysis of these tumors usually reveals cytokeratin, vimentin, epithelial membrane antigen, and (less frequently) S-100 protein and neuron-specific enolase. Local excision is curative for endolymphatic sac papillary tumors. The currently favored method of treatment consists of excision and long-term follow-up. The role of adjuvant radiotherapy as treatment is controversial. This case report describes an endolymphatic sac tumor in a 22-year-old woman without von Hippel-Lindau disease who had a number of complaints, including deafness in her left ear, complete left-sided facial paralysis, and hoarseness of approximately 8 years' duration.

Abstract
We present a case of papillary cystic low-grade adenocarcinoma of endolymphatic sac origin. These tumors are very rare and only a few cases have been reported in literature. They have a protracted clinical course causing progressive invasion and bony destruction. Radiologically, they appear as a heterogenous lobulated vascular mass, invading bone and compressing surrounding structures. Histologically, these tumors are composed of uniform population of cells, resembling normal endolymphatic sac epithelium. This causes considerable diagnostic difficulty. A strong index of suspicion along with clinical and radiological correlation is essential to arrive at a correct diagnosis. In some bilateral cases, association with von Hippel-Lindau disease has been noted. Radical mastoidectomy and temporal bone resection, which may sometimes necessitate sacrifice of cranial nerves, is the treatment of choice.

Abstract
We report a case of endolymphatic sac tumor (ELST). A 48-year-old female had recurrent and slowly progressive hearing loss, accompanied with dizziness like Meniere's disease. A tumor was located around the semicircular canals, and was detected on CT and MRI. The patient underwent total removal of the tumor using a transmastoid approach. Histopathological examinations agreed with features of an ELST. The tumor was highly suspected to have originated from the rugose portion of the endolymphatic sac or the endolymphatic duct, based on surgical and imaging studies. Structure of the membranous labyrinth was preserved regardless of the existence of the tumor around semicircular canals with bone destruction. ELSTs seem to have an osteolytic or osteophilic nature, by examining patterns of tumor infiltration.

Abstract
OBJECTIVE Endolymphatic sac tumors are aggressive papillary tumors of the temporal bone frequently associated with von Hippel-Lindau disease. The goal of this study was to use a newly devised classification system as a means to analyze differences between endolymphatic sac tumor extension in von Hippel-Lindau disease and non-von Hippel-Lindau disease patients. METHODS Previously reported cases of endolymphatic sac tumor and two new cases were retrospectively reviewed and assigned to a new classification system consisting of four grades based on tumor extent and location. RESULTS Mean age of 103 patients without von Hippel-Lindau disease was 52.5 years, whereas in 46 patients with VHL the mean age was 31.3 years. Patients with von Hippel-Lindau disease were more likely to be female (female-to male ratio of 2:1 for von Hippel-Lindau disease patients versus 1:1 for non-von Hippel-Lindau disease patients). Symptoms consisted of hearing loss (100% [mean duration, 10 yr] for VHL patients versus 97% [mean duration, 7.8 yr] for non-von Hippel-Lindau disease patients), facial weakness (38% versus 49%), and tinnitus or vertigo (41% versus 60%). Bilateral tumors were common in von Hippel-Lindau disease patients (28% versus 1%). Tumors in von Hippel-Lindau disease patients were significantly more likely to be lower grade than tumors in non-von Hippel-Lindau disease patients (Grade I, 40% versus 25%; Grade II, 50% versus 58%; Grade III, 8% versus 14%; and Grade IV, 2% versus 4%; p < 0.05). Before 1988, there were relatively fewer Grade I (15% versus 33%) and relatively more Grade II (69% versus 47%) endolymphatic sac tumors in non-von Hippel-Lindau disease patients than after 1988. CONCLUSIONS Increased usefulness of intracranial imaging since 1988 has led to the diagnosis of sporadic endolymphatic sac tumors with lower grades. Surveillance imaging in von Hippel-Lindau disease may account for the greater proportion of endolymphatic sac tumors diagnosed with lower grades. Endolymphatic sac tumors associated with a diagnosis of von Hippel-Lindau disease appear to affect a younger population of patients than non-von Hippel-Lindau disease cases and occur in women twice as often as in men when associated with von Hippel-Lindau disease. In addition, tumors are more frequently bilateral and less advanced in the von Hippel-Lindau disease patient as opposed to the non-von Hippel-Lindau disease patient.

Abstract
A 44-year-old man presented with an endolymphatic sac tumor (ELST) associated with von Hippel-Lindau disease, which required four surgical procedures within 10 years. The earlier two surgeries resulted in only partial removal of the tumor because of vigorous intraoperative bleeding. Stereotactic radiation therapy was performed twice. The intraoperative bleeding was easy to control in the third operation, and ultimately the tumor was totally extirpated in the fourth operation. Histological examination of the tumor specimen harvested in the final surgery showed that the tumor cells had clearly decreased in number, and the interstitial tissue had become fibrous with organization of the tumor vessels, compared with the tumor specimen from the first surgery. Preoperative radiotherapy may be effective to reduce the devastating intraoperative bleeding of ELST.

Abstract
The entity which has come to be known as an endolymphatic sac tumor (ELST) has, in the past, been known as adenocarcinoma of endolymphatic sac origin, aggressive papillary tumor of the temporal bone and Heffner's tumor. ELSTs arise in the vicinity of the inner ear and may extend to involve both the posterior fossa as well as the middle ear and the external ear canal, which may complicate the differential diagnosis ELSTs are typically seen in adults, with only rare descriptions in pediatric patients. They may be sporadic tumors or they may arise as part of the symptom complex of von Hippel-Lindau disease. Clinical signs at presentation range from a mass in the external ear canal to sensorineural deafness to cranial nerve palsies. Imaging studies reveal a destructive lesion of the petrous bone which is heterogeneous on MR scanning. Light microscopy reveals two chief patterns: a follicular pattern, reminiscent of thyroid parenchyma; and a papillary/solid pattern. Both patterns are often admixed in the same tumor, and the individual tumor cells are cytologically bland. Immunohistochemically, ELSTs are typically keratin-, vimentin- and epithelial membrane antigen-positive; they are often S-100 protein-positive and neuron-specific enolase-positive as well. ELSTs are difficult to extirpate surgically (owing to their locally aggressive nature); nevertheless, surgical excision remains the mainstay of current therapy. These are slow-growing (albeit locally aggressive) tumors which have only rarely been reported to metastasize; as such, they remain principally a problem of local control.

Abstract
BACKGROUND Papillary tumors of the temporal bone are very rare neoplasms that show locally aggressive behavior though they have low-grade histologic features. The best treatment for these tumors is a radical resection. However, if the tumor is very large, local invasiveness and hypervascularity can prevent surgeons from achieving a complete resection. As an additional treatment for the residual tumor, it remains controversial whether radiation therapy has any role. CASE DESCRIPTION The authors describe a 53-year-old woman who suffered from left-sided tinnitus, hearing loss, and diplopia due to a large aggressive papillary tumor of the temporal bone. Radiosurgery was very effective for the tumor, which had regrown a few years after conventional radiation therapy and chemotherapy. CONCLUSIONS The authors conclude that radiosurgery should be considered as an option for the treatment of aggressive papillary tumor of the temporal bone.

A 77-year-old man presented with decreased mental status and an enhancing partially cystic tumor along the left tentorium on magnetic resonance imaging after mastoidectomy and petrosectomy for an "auditory canal tumor." Smears of the aspirated cyst fluid revealed rare epithelial cell clusters, some with papillary features, foamy macrophages, and blood. The cells were orderly, with fairly bland nuclei and well-defined cell borders. The cell block contained similar epithelium, with cells containing eosinophilic and focally vacuolated cytoplasm, some with pigmented granules resembling hemosiderin. Numerous foam cells were also present. Review of the patient's previous and concurrent resection material showed an endolymphatic sac tumor, a rare neoplasm that arises in the endolymphatic sac in the temporal bone. The previously undescribed cytologic features of this rare neoplasm are discussed.

Abstract
The authors report a case of endolymphatic sac tumor (ELST) associated with Von Hippel-Lindau disease (VHL). A 20-year-old female VHL patient received a resection of a cerebellar hemangioblastoma 3 years ago and she had a co-existing of left petrous tumor. The petrous tumor showed a remarkable progression in 3 years and was resected subtotally. Histologically, the resected petrous tumor showed a papillary structure containing cuboidal or columnar cells with fibrous stroma and numerous microvessels and destructed temporal bone, all of which are consistent with ELST. We studied the expression of various kinds of cytokeratins (CKs) immunohistochemically and found distinct expression of CKs (CAM 5.2, 34betaE-12, CK7, CK8 and CK19), but not for CK10/13 or CK20. Vascular endothelial growth factor and neuron specific enolase showed strong immunoreactivity in the tumor cells. CD34 also had weak expression. Ki-67 antigen (MIB-1) immunoreactivity was found in focal areas, and the labeling index in the highest-density area was 48.9%. These findings suggest that vascular endothelial growth factor overexpression is an important factor for angiogenesis in ELST, much like other VHL-associated tumors, and that ELST may have a more highly aggressive component than the low-grade malignancy noted in previous reports.

Abstract
A 72-year-old man developed left facial palsy at age 14 and left-sided hearing loss at age 20. At the age of 59, he presented with gait disturbance, and a large left cerebellopontine angle tumor was detected, which had markedly destroyed the pyramidal bone. The tumor was subtotally resected, but he required two more operations at the ages of 64 and 69 because of tumor regrowth. At the present time, recurrent tumor has destroyed the occipital bone and is invading the scalp. However, even though he has several cranial nerve palsies and cerebellar ataxia, he remains in stable condition and demonstrates long-term survival. The patient's surgical specimens revealed a papillary adenoma, which was recently thought to be of endolymphatic sac origin, although the origin of this kind of tumor, whether arising from the middle ear or from the endolymphatic sac, has not been established with certainty so far. In this paper, we provide further evidence that this tumor originates from the endolymphatic sac, based on anatomical, histopathological, and embryological evidence.

Abstract
A primary adenomatous tumor of the middle ear was examined by light microscopy, ultrastructural and immunohistochemical techniques. In support of its extensive neuroendocrine differentiation, was the diffuse detection of neuron-specific enolase (NSE) and positive immunoreaction with antibodies to chromogranin and synaptophysin. The great majority of tumor cells contained neurosecretory granules and intraluminal mucin production could be focally detected. These characteristics confirm the diagnosis of a middle ear adenomatous tumor (MEAT) of a biphasic nature and with a prominent neuroendocrine component.
