1/25. endolymphatic sac tumor: a case report.Papillary tumors of the temporal bone are aggressive neoplasms which may occur sporadically or as a part of von hippel-lindau disease. The term 'endolymphatic sac tumor' identifies the origin of these rare tumors. The clinical manifestations are sensorineural hearing loss, facial paralysis, cerebellar disorders and vertigo. The tumor is locally invasive, destructive and hypervascular exhibiting consistent imaging and histopathologic features. The treatment of choice is the total removal of the lesion although complete excision of the advanced lesion is nearly impossible due to the anatomic complexity of the endolymphatic sac and distinct patterns of extension. We present a 50-year-old male patient with endolymphatic sac tumor with left sided sensorineural hearing loss and review the literature.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/25. facial paralysis with an inflammatory parotid mass.facial paralysis in association with a parotid mass is usually associated with a diagnosis of malignancy. Benign parotid neoplasms and inflammatory processes resulting in facial paralysis are extremely rare. This report describes such a case and highlights some of the difficulties surrounding the diagnosis and management of these cases.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
3/25. Bilateral peripheral facial palsy secondary to lymphoma in a patient with hiv/AIDS: a case report and literature review.Neurological complications represent one of the most important causes of morbidity and mortality in patients with hiv/AIDS. However, peripheral neuropathy comprises only 5% to 20% of the total neurological complications and facial nerve palsy, especially when it is bilateral, is a less common manifestation. Peripheral facial palsy has been considered as a possible neurological complication of the early stage of hiv infection but the number of reported cases in the literature is limited. Histological findings of nervous tissue in peripheral facial palsy at an early stage of hiv infection include a degenerative and not suppurative inflammatory process, but its etiology remains obscure. Peripheral facial palsy in the late stage of hiv infection is characterized by an advanced immunological deficit and generally it is secondary to an opportunistic infection of the CNS, such as neurotoxoplasmosis and lymphoma. However, this peripheral attack of the facial nerve is not very common at this late stage of hiv infection. Bilateral peripheral facial palsy as a complication of non-Hodgkin s lymphoma is considered an extremely rare entity. There are no published reports of bilateral peripheral facial palsy secondary to lymphomas or other neoplasms of the CNS in immunosuppressed patients. Non-Hodgkin s lymphoma (NHL) has been considered a late and relatively common manifestation of hiv infection, but an exact cause for the higher incidence of this malignant neoplasm in hiv/AIDS patients is still uncertain.- - - - - - - - - - ranking = 2keywords = neoplasm (Clic here for more details about this article) |
4/25. facial paralysis caused by malignant skull base neoplasms.OBJECT: bell palsy remains the most common cause of facial paralysis. Unfortunately, this term is often erroneously applied to all cases of facial paralysis. methods: The authors performed a retrospective review of data obtained in 11 patients who were treated at a university-based referral practice between July 1988 and September 2001 and who presented with acute facial nerve paralysis mimicking bell palsy. All patients were subsequently found to harbor an occult skull base neoplasm. A delay in diagnosis was demonstrated in all cases. Seven patients died of their disease, and four patients are currently free of disease. CONCLUSIONS: Although bell palsy remains the most common cause of peripheral facial nerve paralysis, patients in whom neoplasms invade the facial nerve may present with acute paralysis mimicking bell palsy that fails to resolve. Delays in diagnosis and treatment in such cases may result in increased rates of mortality and morbidity.- - - - - - - - - - ranking = 6keywords = neoplasm (Clic here for more details about this article) |
5/25. Recurrent facial palsy occurring with metastatic thymic carcinoid and nonarteritic ischemic optic neuropathy.A 74-year-old man was diagnosed with thymic carcinoid metastatic to the mediastinum. Two years later, he developed left and then right facial palsy. Four additional episodes of facial palsy developed within 2 years, followed by an occurrence of nonarteritic ischemic optic neuropathy. While recurrent facial palsy is uncommon, it may occur in the presence of various systemic conditions such as carcinoid, diabetes, infection, and neoplasm. The presence of recurrent facial palsy logically warrants an evaluation for systemic disease.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
6/25. Candidal abscess of the parotid gland associated with facial nerve paralysis.facial nerve paralysis associated with parotid gland mass is usually caused by malignant neoplasms and facial nerve dysfunction due to parotid infection is exceedingly rare. A review of the literature revealed approximately 15 cases of facial nerve palsy associated with suppurative parotitis or parotid abscess. We report the first case of candidal abscess of the parotid gland associated with facial nerve paralysis in a 74-year-old insulin-dependent diabetic patient. The differential diagnosis in these unusual cases occurring in diabetic, immunodeficient patients should include candida albicans infection.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
7/25. endolymphatic sac tumor in a 4-year-old boy.INTRODUCTION: endolymphatic sac tumors (ELST) are rare, low-grade, locally aggressive papillary neoplasms. We present a case of a 4-year-old boy with an ELST, the youngest described in the literature. CASE: A boy presented with a right-sided serous otitis media and sudden-onset right facial nerve palsy. An audiogram revealed right-sided profound sensorineural hearing loss. Radiographic imaging demonstrated a 3-cm expansile lytic lesion along the posterior face of the petrous bone. INTERVENTION/RESULTS: The patient initially underwent a right transmastoid-infralabyrinthine biopsy. Pathologic examination revealed a papillary lesion suspicious for an ELST. Subsequently, a transtemporal-transcochlear approach with intra-and extradural resection of the tumor was performed. The facial nerve was dissected and transposed anteriorly and preserved. Histopathologic and immunohistochemical studies confirmed the ELST. At his 6-month follow up, there is no evidence of recurrence and the facial nerve function has returned to Grade II palsy. CONCLUSION: ELST are rare tumors of the temporal bone. This is the youngest case of ELST reported. Presentation, evaluation, and management of ELST is discussed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
8/25. germinoma-unusual presentation: a case report.germinoma accounts for two-thirds of germ cell tumors and about 40% of all pineal region neoplasms. This case illustrates an unusual manifestation of metatastic germinoma with spread to ventricles and meninges without a pineal mass. A 24-year-old man presented with nausea, vertigo, and left facial droop. cerebrospinal fluid aspirate showed malignant cells most suggestive of a germinoma.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
9/25. facial paralysis caused by metastasis of breast carcinoma to the temporal bone.Metastatic tumors to the temporal bone are very rare. The most common sites of origin of temporal bone metastases are breast, lung, kidney, gastrointestinal tract, larynx, prostate gland, and thyroid gland. The pathogenesis of spread to the temporal bone is most commonly by the hematogenous route. The common otologic symptoms that manifest with facial nerve paralysis are often thought to be due to a mastoid infection. Here is a report on a case of breast carcinoma presenting with otalgia, otorrhea, and facial paralysis for 2 months. The patient was initially diagnosed as mastoiditis, and later the clinical impression was revised to metastatic breast carcinoma to temporal bone, based on the pathologic findings. Metastatic disease should be considered as a possible etiology in patients with a clinical history of malignant neoplasms presenting with common otologic or vestibular symptoms, especially with facial nerve paralysis.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
