Temporal bone meningioma involving the middle ear: A case report

Abstract. Meningioma is a common intracranial tumor involving the meninges. The localization of this type of tumor is rarely extracranial due to its typically low invasive properties. Furthermore, invasion of the middle ear is exceptional. The present study reported a case of meningioma extending into the middle ear from the middle cranial fossa through the tegmen tympani. The clinical and pathological characteristics, as well as the outcome of the patient, were described. IntroductionMeningioma is a common intracranial tumour, accounting for 13-19% of all primary brain tumors (1). This tumor is generally encapsulated and benign (2). The symptoms of meningioma depend on the pressure of the tumor on the brain or spinal cord and the intracranial location of the tumor (3). Symptoms, such as seizures, single or multiple muscle twitches, spasms, loss of control of body functions, change in sensation and partial or total loss of consciousness, are associated with the different locations of the mass (1,4). Meningiomas accounted for ~33.8% of all the primary brain and central nervous system tumors reported in the United States between 2002 and 2006 (2). Furthermore, in recent decades, increased exposure to risk factors has determined an increase in the incidence of primary brain tumors, inclusive of meningioma, in several countries (5). The predominant risk factor identified is the exposure to ionizing radiation; however, other risk factors may be associated with the risk of meningioma, including elevated estrogen and/or progesterone hormone levels (2,6,7), head trauma (2), cell phone use (2,8), breast cancer (2), occupation (2), diet (2). Notably, a significant inverse correlation has been identified between meningioma and allergies (2,9); Linos et al (10) revealed that individuals with a history of allergy exhibited a lower risk of developing brain tumours than individuals with no history of allergy. Meningiomas have a higher incidence rate among female individuals, with a female to male ratio of ~2:1 (5). In addition, age-specific incidence rates indicate that risk increases with age. Prevalence rates for non-Hispanic individuals of African descent are marginally higher (6.67 per 100,000 persons) compared with Caucasian non-Hispanic and Hispanic individuals (5.90 and 5.94 per 100,000 persons, respectively) (2,4). The primary treatment strategy for meningiomas is total resection surgery if the tumor is benign and in an area of the brain where it can be safely and completely removed. Subsequently, radiation therapy is applied for the most malignant cases of meningioma or when surgery is not feasible due to the meningioma location.Extracranial meningiomas are uncommon (accounting for <2% of meningiomas) (11), particularly those extending into the middle ear. The present study described a rare case of meningioma extending into the middle ear from the middle cranial fossa through the tegmen tympani. Written informed consent was obtained from the patient.

“…10,11 Surgery is the preferred treatment for such lesions. 6,7,9,12,13 The role of radiotherapy for such lesions is not defined but may include control of residual microscopic disease and reduction of the recurrence rate in the case of subtotal tumour excision. 14 CLINICAL RECORD approach should have been used rather than the jugular foramen approach, as the latter is associated with macroscopic tumour residuum.…”

“…A review of the literature, including pathogenesis and treatment, is presented Because of the very slow growth rate of such tumours, most authors have suggested long-term clinical and radiological follow up of such patients; long-term follow up is also recommended even after an apparently extracranial tumour is removed, to exclude intracranial disease. 7,8,12 There is no consensus as to whether CT or MRI is the imaging modality of choice in this setting. 15…”

Cerebellopontine angle meningioma resulting in middle-ear polyp

Extracranial spread of meningiomas to involve the middle ear is very rare. We present the case of a 43-year-old woman with a known cerebellopontine angle meningioma who subsequently presented with left-sided otalgia and a middle-ear mass extruding through the tympanic membrane due to local invasion of the meningioma. The tumour was excised surgically. A discussion of the relevant literature is also presented.

“…Daneshi et al 13 document a primary meningioma of the ethmoid sinus. Ex-tracranial meningiomas may also occur in the ear, either as extension into the middle or external ear of an intrapetrous meningioma [14][15][16] or de novo in the external meatus without obvious intracranial connection. 15,17 Extracranial meningiomas may also occur in the neck, as with the case we describe.…”

A case of a patient with a posterior fossa meningioma extending through the hypoglossal canal to the cervical region as described in this article has not been previously described in the literature. Investigations and surgical management are outlined and pathological classifications are discussed. A literature review including recent reports of extracranial meningiomas is presented. Extracranial meningiomas are exceedingly rare and a high index of suspicion is necessary to make the diagnosis.KEYWORDS: Extracranial meningioma, posterior fossa meningioma, carotid artery occlusion, thyroplasty, meningioma classification Meningiomas are common tumors of the nervous system, representing 18% of primary intracranial tumors and 25% of primary intraspinal tumors. 1 Meningiomas appear to be more common in Africans and represent almost 30% of primary intracranial tumors. 2 Extracranial and extraspinal meningiomas are rare with an incidence of 1 to 2%. 3 Extension of intracranial meningiomas to the parapharyngeal and cervical regions is exceedingly rare. 4 The clinical diagnosis of cervical meningiomas can be difficult as more common cervical tumors such as metastatic epithelial tumors, schwannomas, or paragangliomas are likely to be suspected first. 5 We report on a meningioma with intracranial and extracranial components that presents with a cervical mass.
