Abstract
OBJECTIVE To describe the imaging features of primary intraosseous meningiomas (PIMs) to aid an accurate diagnosis. METHODS Clinical materials and radiological data for 9 patients with pathologically confirmed PIMs were reviewed comprehensively. RESULTS Most lesions involved inner and outer plates of the calvaria and all were relatively well circumscribed. Upon computed tomography, portions of the solid neoplasm were hyperattenuated or isoattenuated. Hyperostosis was found in many lesions, but calcification was seen rarely. On magnetic resonance imaging, most neoplasms were hypointense on T1-weighted images, hyperintense on T2-weighted images, and heterogeneous on fluid-attenuated inversion recovery images. In most cases, the soft tissue of neoplasms showed hyperintense on diffusion-weighted imaging and hypointense on apparent diffusion coefficient. All lesions were obviously enhanced after gadolinium administration. Each patient accepted surgical treatment and recurrence was not observed during follow-up. CONCLUSIONS Primary intraosseous meningiomas are very rare tumors that occur usually in later life. They are well-defined and tend to involve the inner and outer plates of the calvaria, with a classic appearance of hyperostosis on computed tomography. Primary intraosseous meningiomas display hypointense on T1-weighted images, hyperintense on T2-weighted images, and hyperattenuated or isoattenuated on computed tomography. Hyperintense on diffusion-weighted imaging, hypointense on apparent diffusion coefficient can also be found. Obvious enhancement supplied additional information for an accurate diagnosis. A neoplasm with these features should raise the suspicion of a PIM.

Abstract
BACKGROUND Primary extracranial meningiomas are uncommon neoplasms. In particular, meningioma involving the hypoglossal canal is extremely rare, with only 4 cases reported in the literature so far. Given that each of these meningiomas originated in the juxtacondyle region with involvement of the hypoglossal canal, to the best of our knowledge, a meningioma that exists only within the hypoglossal canal has yet to be reported. CASE DESCRIPTION We present a case of primary extracranial meningioma arising solely from the hypoglossal canal. A 62-year-old woman presented with long-term difficulty in tongue movement. Her tongue was deviated to the right, and neurologic examination revealed fasciculation and muscle wasting on the right side of the tongue. Computed tomography revealed a calcification in the right hypoglossal canal. Magnetic resonance imaging further demonstrated a hypointense tumor on both T1-weighted and T2-weighted images, with contrast enhancement in the right condyle. Total tumor removal was performed via a transcondylar approach, and histopathologic examination confirmed the presence of a transitional meningioma. No recurrence was observed at 14 months of follow-up. The patient's tongue atrophy was slightly improved, and the deviation completely disappeared. CONCLUSIONS In this extremely rare case of hypoglossal canal meningioma, total tumor removal via a transcondylar approach resulted in the recovery of hypoglossal nerve function.

Abstract
BACKGROUND Sclerotic tumours of the calvarial bones are rare and may be due to primary and secondary bone tumours as well as extradural tumours of meningeal origin. CASE PRESENTATION We report a case of primary intraosseous meningioma (PIM) which arose in the frontal bone of a 63 year old woman who complained of progressive pain and thickening of the right skull. Radiology showed a large osteosclerotic lesion in the right frontal bone. Histology showed an intraosseous lesion containing dense fibrous tissue in which there were scattered cells that expressed epithelial membrane antigen and progesterone receptor. The tumour was partially resected and 3 years after operation has not recurred. CONCLUSIONS PIM is a rare tumour which needs to be distinguished from primary/secondary osteosclerotic calvarial bone tumours.

Abstract
PURPOSE To determine outcomes in the management of extracranial meningiomas of the head and neck. PATIENTS AND METHODS This is a retrospective single-surgeon series performed at a tertiary-care referral center. In all, 23 patients met the inclusion criteria, consisting of 12 men and 11 women. The mean age of patients treated was 60.5 years (range, 32 to 71 years). Subsite involvement included the infratemporal fossa (n = 8), greater wing of the sphenoid and orbit (n = 7), clivus (n = 2), and parapharyngeal space (n = 6). RESULTS In all, recurrence occurred in 21% of patients (n = 5) who underwent gross tumor resection. Two patients underwent subtotal resection because of the tumor's location within the clivus with adjuvant CyberKnife therapy (Accuray, Sunnyvale, CA). Both patients had persistent disease with no new neurologic symptoms. Examination showed that 100% of patients (N = 23) had dural involvement. Post-ablative complications occurred in 43% of patients (n = 10). CONCLUSIONS We presently report the largest series of surgical treatment for extracranial meningiomas. Gross tumor resection should be the mainstay of therapy, except in anatomically restricted regions such as the petrous apex and clivus. Adjuvant therapy including CyberKnife therapy may be used in such lesions. All lesions showed dural involvement. A more unified nomenclature is required for the characterization of these lesions.

Abstract
INTRODUCTION Extracranial meningiomas may infrequently be encountered as ectopic or metastatic tumors. Their rarity and unique cytomorphology often pose significant diagnostic dilemmas. The aim of this study was to report our experience with a series of ectopic and metastatic meningiomas, characterizing their cytomorphology with histological correlation. MATERIALS AND METHODS A retrospective analysis involving 13 patients with cytological preparations from extracranial meningiomas was performed. Cytology cases were correlated with available surgical resection specimens. Data regarding clinical findings, tumor information, cytomorphology, follow-up histological features and immunohistochemistry were recorded and analyzed. RESULTS There were 5 cases with metastases and 8 ectopic meningiomas. Metastases occurred in the scalp/skull, lung, paraspinal soft tissue and liver. Primary ectopic meningiomas were located in the paranasal sinuses and ear, orbit and neck. Cytomorphological features characteristic of meningiomas were identified in the majority of samples including tightly cohesive clusters of spindled cells, whorls, intranuclear inclusions, nuclear grooves and psammomatous calcification. Unusual cytomorphological features identified in only a few cases included epithelioid cell predominance, abundant inflammatory cells, small-cell change, papillary structures and pseudoacinar growth. Metastatic tumors exhibited more nuclear atypia and occasionally mitoses or necrosis. Meningiomas were shown to be immunoreactive for epithelial membrane antigen, pancytokeratin and vimentin. CONCLUSION Although rare, extracranial meningiomas can be encountered in cytologic specimens and should be included in the differential diagnosis when characteristic morphological features of meningiomas are seen. Cytopathologists should be aware that these lesions could be mistaken for other tumors, especially when confounded by atypia and unusual cytomorphological features.

Abstract
We have described a primary esophageal meningioma (MG) clinical case diagnosed in a 62-year-old woman; also, we review the literature about extracranial MGs. To our knowledge, this is the first case report of an extracranial MG occurring primarily in the esophagus. These are benign neoplasms reported classically in the central nervous system (CNS). The extrancranial MGs have histopathologic and inmunohistochemical features identical to those observed in CNS MGs; thus, the main diagnostic hurdle is to keep it in the differential for lesions occurring outside the CNS.

Abstract
Meningiomas are common intracranial tumours which rarely extend to extra cranial sites. Here, the authors report a rare case of an intracranial meningioma with extracranial spread into the subcutaneous tissues of the scalp, with a brief overview of the literature. An 82-year-old man presented following a fall. At the time of assessment, it was noted that he had a large deformity over the frontal area of his scalp. It was unclear as to the duration of this deformity. Following an inconclusive CT head he underwent a MRI head which revealed an intracranial mass which extended across the frontal lobes. The mass permeated through the skull and extended through to the scalp. He underwent a biopsy of the extracranial component. The histology of which suggested a benign meningioma with low mitotic activity.

Abstract
Meningiomas involving the temporal bone may originate from arachnoid cell nests present within the temporal bone (intratemporal), but more frequently originate from arachnoid cell nests of the posterior or middle cranial fossa with secondary invasion of the TB (extratemporal). In this study, we retrospectively reviewed the charts of 13 patients with meningiomas involving the temporal bone who underwent surgery. Tumors of the posterior fossa with only temporal bone hyperostosis, but without invasion, were excluded. Patients presented primarily with otologic symptoms and signs. The tumors originated in the temporal bone (5/13), jugular foramen (4/13), petroclival region (2/13), the asterion (1/13) or the internal auditory meatus (1/13). All of the intratemporal meningiomas had the radiological appearance of en-plaque menigiomas. The tumor extended into the middle ear (11/13), eustachian tube (5/13), and/or the labyrinth (3/13). A gross total resection was achieved in 11 patients and a subtotal resection in 2 patients. The lower cranial nerves were infiltrated by tumor in 4 patients, and were sacrificed. At a mean follow-up of approximately 6 years, 12 patients are currently alive and doing well and 1 died from tumor progression. Six patients showed tumor recurrence and were reoperated on (5/6) or followed conservatively (1/6). Surgical treatment of temporal bone meningiomas is associated with high recurrence rate due to indiscreet tumor margins. Combined surgical approaches (temporal craniotomy and mastoidectomy) by neurosurgical and otological teams are recommended for meningiomas originating in the temporal bone.

Abstract
We have examined the clinical characteristics and treatment of ectopic meningiomas (EMs). Samples from 17 patients with EMs were analyzed, and their clinical characteristics, mechanism, and treatment were studied in combination with the literature. The main clinical manifestations of EMs included increased intracranial pressure, epilepsy, local mass, and local occupying effects, but diagnosis of EMs depended on the pathology. Surgical removal can achieve the double objectives of confirmed diagnosis and treatment of tumors. The clinical characteristics of EMs vary with the sites of tumors. Operation is the treatment of first choice. Prognosis is better than that of typical meningiomas.

Abstract
Primary extracranial meningiomas are rare neoplasms, frequently misdiagnosed, resulting in inappropriate clinical management. To date, a large clinicopathologic study has not been reported. One hundred and forty-six cases diagnosed between 1970 and 1999 were retrieved from the files of the Armed Forces Institute of Pathology. Histologic features were reviewed, immunohistochemistry analysis was performed (n = 85), and patient follow-up was obtained (n = 110). The patients included 74 (50.7%) females and 72 (49.3%) males. Tumors of the skin were much more common in males than females (1.7:1). There was an overall mean age at presentation of 42.4 years, with a range of 0.3-88 years. The overall mean age at presentation was significantly younger for skin primaries (36.2 years) than for ear (50.1 years) and nasal cavity (47.1 years) primaries. Symptoms were in general non-specific and reflected the anatomic site of involvement, affecting the following areas in order of frequency: scalp skin (40.4%), ear and temporal bone (26%), and sinonasal tract (24%). The tumors ranged in size from 0.5 up to 8 cm, with a mean size of 2.3 cm. Histologically, the majority of tumors were meningothelial (77.4%), followed by atypical (7.5%), psammomatous (4.1%) and anaplastic (2.7%). Psammoma bodies were present in 45 tumors (30.8%), and bone invasion in 31 (21.2%) of tumors. The vast majority were WHO Grade I tumors (87.7%), followed by Grade II (9.6%) and Grade III (2.7%) tumors. Immunohistochemically, the tumor cells labeled for EMA (76%; 61/80), S-100 protein (19%; 15/78), CK 7 (22%; 12/55), and while there was ki-67 labeling in 27% (21/78), <3% of cells were positive. The differential diagnosis included a number of mesenchymal and epithelial tumors (paraganglioma, schwannoma, carcinoma, melanoma, neuroendocrine adenoma of the middle ear), depending on the anatomic site of involvement. Treatment and follow-up was available in 110 patients: Biopsy, local excision, or wide excision was employed. Follow-up time ranged from 1 month to 32 years, with an average of 14.5 years. Recurrences were noted in 26 (23.6%) patients, who were further managed by additional surgery. At last follow-up, recurrent disease was persistent in 15 patients (mean, 7.7 years): 13 patients were dead (died with disease) and two were alive; the remaining patients were disease free (alive 60, mean 19.0 years, dead 35, mean 9.6 years). There is no statistically significant difference in 5-year survival rates by site: ear and temporal bone: 83.3%; nasal cavity: 81.8%; scalp skin: 78.5%; other sites: 65.5% (P = 0.155). Meningiomas can present in a wide variety of sites, especially within the head and neck region. They behave as slow-growing neoplasms with a good prognosis, with longest survival associated with younger age, and complete resection. Awareness of this diagnosis in an unexpected location will help to avoid potential difficulties associated with the diagnosis and management of these tumors.

Abstract
Meningiomas are the most common of the benign intracranial neoplasms. They are uncommon as primary or secondary extracranial entities. Of these, the primary intraosseous variant may represent the rarest form. We report the case of a rare primary intraosseous meningioma presenting as a localized, symptom-free supraorbital bony expansion in an 81-year-old female patient and tabulate the previously reported cases of primary intraosseous meningiomas of the craniomaxillofacial region for analysis.

Abstract
Primary calvarial or intra-osseous meningiomas are uncommon lesions often confused preoperatively with other primary or secondary bone tumors of the skull. We present details of a patient with a primary calvarial meningioma involving the frontal, zygomatic, sphenoid and temporal bones that was radiographically diagnosed as fibrous dysplasia and initially treated conservatively for many years. Progressive vision loss and significant proptosis, with difficulty of eye closure, prompted surgical removal with cranioplasty and a 3D reconstructed prosthetic flap. Histological examination revealed intra-osseous meningioma. The clinical and radiological findings of intra-osseous meningiomas are discussed, together with a review of the literature.

Abstract
BACKGROUND Extracranial meningioma is a rare tumor, and most of the time only after histopathologic examination is diagnosis possible. CASE DESCRIPTION A 40-year-old right-handed woman presented with progressive swelling over the right side of the forehead and temporal region associated with proptosis and visual loss. Incisional biopsy of the lesion was reported as spindle cell tumor. Computed tomography scan showed large enhancing predominantly extracranial lesion located in the right anterior frontotemporal region extending into the infratemporal fossa and a relatively thin sheet of tumor on the intracranial aspect of the thickened temporal. Intraoperative impression was malignant tumor involving the temporalis muscle, and a near total excision of the lesion was performed. Histopathologic features were suggestive of meningothelial meningioma arising from the temporal bone with predominant extracranial extension. CONCLUSION Preoperative suspicion of a meningioma in this patient would have resulted in a more aggressive surgical approach as these lesions are relatively benign with indolent course.

Abstract
Object
The authors retrospectively analyzed a consecutive series of patients with cranial vault primary extradural meningioma (PEM), with particular regard to the tumor’s dural involvement. The pertinent literature was reviewed.
Methods
Clinical data were retrospectively obtained in a consecutive series of 16 patients treated for a PEM at two institutions between 1992 and 2004. The authors created a classification system based on dural involvement of the tumors.
Nine women and six men (mean age 55 years) presented with a painless, slowly progressive swelling. Preoperative magnetic resonance (MR) imaging revealed dural enhancement at the site of tumor in 11 patients. On surgical inspection, the tumor infiltrated the dura in all but three patients. Histological examination of tissue samples demonstrated tumor infiltration of the dura in all 14 patients in whom the dura had been resected. Three recurrent tumors were observed on follow-up examination during a mean period of 5.8 years (range 1.5–13 years) and required extirpation. In addition to one patient in whom there was histological evidence of malignancy, the other two cases involved two patients in whom no apparent dural involvement was observed during the first surgery. In a review of the literature, the authors found that histological examination showed dural involvement in 22%; the dura was not histologically evaluated in the remaining patients (78%). Postoperative follow-up data exceeding 2 years were only provided in two of the reported cases.
Conclusions
Tumor infiltration of the dura should be assumed in PEMs of the cranial vault, and resection of the dura at the site of craniotomy is recommended to prevent tumor recurrence.

Abstract
"Primary" ear and temporal bone meningiomas are tumors that are frequently misdiagnosed and unrecognized, resulting in inappropriate clinical management. To date, a large clinicopathologic study of meningiomas in this anatomic site has not been reported. Thirty-six cases of ear and temporal bone meningiomas diagnosed between 1970 and 1996 were retrieved from our files. Histologic features were reviewed, immunohistochemical analysis was performed (n = 19), and patient follow-up was obtained (n = 35). The patients included 24 females and 12 males, aged 10-80 years (mean, 49.6 years), with female patients presenting at an older age (mean, 52.0 years) than male patients (mean, 44.8 years). Patients presented clinically with hearing changes (n = 20), otitis (n = 7), pain (n = 5), and/or dizziness/vertigo (n = 3). Symptoms were present for an average of 24.6 months. The tumors affected the middle ear (n = 25), external auditory canal (n = 4), or a combination of temporal bone and middle ear (n = 7). The tumors ranged in size from 0.5 to 4.5 cm in greatest dimension (mean, 1.2 cm). Radiographic studies demonstrated a central nervous system connection in 2 patients. Histologically, the tumors demonstrated features similar to those of intracranial meningiomas, including meningothelial (n = 33), psammomatous (n = 2), and atypical (n = 1). An associated cholesteatoma was identified in 9 cases. Immunohistochemical studies confirmed the diagnosis of meningioma with positive reactions for epithelial membrane antigen (79%) and vimentin (100%). The differential diagnosis includes paraganglioma, schwannoma, carcinoma, melanoma, and middle ear adenoma. Surgical excision was used in all patients. Ten patients developed a recurrence from 5 months to 2 years later. Five patients died with recurrent disease (mean, 3.5 years), and the remaining 30 patients were alive (n = 25, mean: 19.0 years) or had died (n = 5, mean: 9.5 years) of unrelated causes without evidence of disease. We conclude that extracranial ear and temporal bone meningiomas are rare tumors histologically similar to their intracranial counterparts. They behave as slow-growing neoplasms with a good overall prognosis (raw 5-y survival, 83%). Extent of surgical excision is probably the most important factor in determining outlook because recurrences develop in 28% of cases.

Abstract
OBJECT Primary jugular fossa meningomas (JFMs) are one of the rarest subgroups of meningioma, with fewer than 40 cases reported in the literature. The authors retrospectively analyzed the results of surgical treatment in their series of patients, including clinical, pathological, and complication features. The surgical approach was mandated by the pathological anatomy of the tumor as well as by the anatomy of the individual patient. METHODS During a 6.5-year period, the authors performed nine surgeries in eight patients (seven women [88%] and one man [12%]) with JFMs. Six lesions occurred on the right side and two on the left. The most common presenting symptoms were altered hearing in five patients (62%), swallowing difficulties in four patients (50%), and a deficit of the 11th cranial nerve in three patients (38%); a combination of two or more signs or symptoms was common. The surgical approach was tailored to the local anatomy (tumor-neurovascular relationships) found in each patient; three different routes were used. Radical tumor removal was achieved in all patients; one tumor recurrence occurred after 20 months in a patient in whom the tumor had displayed atypical histological features. This woman underwent a second operation. The mean length of hospital stay was 1 week. The mean and the median follow-up period were 45 and 40 months, respectively. The most common complications were transient lower cranial nerve deficits, which resolved or were compensated for in all patients within 1 month. CONCLUSIONS With a careful, extensive preoperative evaluation and appropriate tailoring of the operative approach, JFMs can be radically resected with the expectation of good outcome.

Abstract
Extracranial meningiomas are rare tumors, comprising approximately 2% of all meningiomas. Previously reported sites include the orbit, parapharyngeal space, and rarely, the paranasal sinuses. A retrospective chart review of patients with meningiomas was performed over the last 25 years, and three patients were identified with meningiomas involving the paranasal sinuses. The locations included the frontal sinus, the ethmoid sinus, and the sphenoid sinus. Presenting symptoms included facial pain and nasal obstruction; two patients noted facial swelling. Diagnosis was established via endoscopic transnasal biopsy in two patients. Computed tomographic (CT) guided biopsy was utilized to confirm the diagnosis in the third patient. Surgical extirpation was successfully performed with tumors arising from the ethmoid and frontal sinuses. The patient with neoplasm in the sphenoid sinus underwent radiation therapy. Extracranial meningiomas of the paranasal sinuses are rare tumors that may present a diagnostic and therapeutic challenge. We present three cases and discuss the clinical presentation, radiographic findings, diagnostic evaluation, and treatment options.

Abstract
A 77-year-old woman with neurofibromatosis type 1 presented with ill-fitting dentures due to intraoral extension of a right temporal fossa mass. Computed tomographic scanning demonstrated that the masticator space mass bowed the zygomatic arch and remodeled the lateral orbit and maxillary sinus walls, findings that were consistent with the clinical diagnosis of a neurofibroma with possible malignant transformation. However, light microscopic, immunohistochemical, and ultrastructural examination of tissue from an incisional biopsy specimen were diagnostic of meningioma. This case illustrates that the clinicopathologic differential diagnosis of an enlarging mass in patient with neurofibromatosis should include sporadic, unrelated neoplasms as well as tumors known to be associated with the syndrome.

Abstract
Extracranial meningiomas of the sinonasal tract are rare tumors. These tumors are frequently misclassified, resulting in inappropriate clinical management. To date, there has been no comprehensive study to evaluate the clinicopathologic aspects of meningioma in these anatomic sites. Thirty cases of sinonasal tract meningiomas diagnosed between 1970 and 1992 were retrieved from the files of the Otorhinolaryngic Registry of the AFIP. Histologic features were reviewed, immunohistochemical studies were performed, patient follow up was obtained, and the results were statistically analyzed. The patients included 15 females and 15 males, aged 13 to 88 years (mean, 47.6 yrs). Patients presented clinically with a mass, epistaxis, sinusitis, pain, visual changes, or nasal obstruction, dependent on the anatomic site of involvement. Symptoms were present for an average of 31.1 months. The tumors affected the nasal cavity (n = 14), nasopharynx (n = 3), frontal sinus (n = 2), sphenoid sinus (n = 2). or a combination of the nasal cavity and ethmoid, frontal, sphenoid, and/or maxillary sinuses (n = 9). The tumors ranged in size from 1.0 to 8.0 cm in greatest dimension (mean, 3.5 cm). Radiographic studies demonstrated a central nervous system connection in six cases. The tumors often eroded the bones of the sinuses (n = 18) and involved the surrounding soft tissues, the orbit, and occasionally the base of the skull. Histologically, the tumors demonstrated features similar to intracranial meningiomas. The majority were of the meningothelial type (n = 23), although there were three atypical meningiomas. Immunohistochemical studies confirmed the diagnosis of meningioma with positive reactions for epithelial membrane antigen (EMA) and vimentin (all tested). The differential diagnosis includes paraganglioma, carcinoma, melanoma, psammomatoid ossifying fibroma, and angiofibroma. Surgical excision was used in all patients. Three patients died with recurrent disease (mean, 1.2 yrs), one was alive with recurrent disease (25.6 years), and the remaining 24 patients were alive or had died of unrelated causes (mean, 13.9 yrs) at the time of last follow up (two patients were lost to follow up). Extracranial sinonasal tract meningiomas are rare tumors which need to be considered in the differential diagnosis of sinonasal tumors. A whorled growth pattern and psammoma bodies, combined with positive EMA and vimentin immunohistochemical reactions, can confirm the diagnosis of meningioma. The overall prognosis is good, without a difference in outcome between benign and atypical meningiomas.

A 29-year-old female with primary ectopic meningioma in the right ethmoid sinus was reported. She was treated by a right lateral rhinotomy with total removal of the tumor and the subsequent clinical course was good. Contrast enhanced magnetic resonance image (MRI) was most informative to define the tumor and decide the surgical procedure, in which it was demonstrated as well circumscribed mass lesion with considerable homogeneous contrast enhancement.

Abstract
A report is made of a primary meningioma intimately associated with the left sphenoid ridge and temporal bone of a 41-year-old woman. The lesion produced hyperostosis of the involved bones, ipsilateral proptosis, and reduced vision for 4.5 years. The radiotherapy yielded little improvement of the exophthalmos and vision. Review of 125 reported meningiomas intimately related to the skull and presenting primarily with hyperostosis and minimal soft tissue component, including the current case, disclosed that all but one affected the cranium proper, particularly the middle ear, temporal bone, frontal bone, and parietal bone. The exceptional one was in the mandible. They tended to occur between the fifth and seventh decades of life with the peak occurrence between the fifth and sixth decades. The average age was 46 years for overall. The female-to-male ratio was 2:1. Six of 125 primary meningiomas closely associated with the skull were malignant and two of these spread to the lungs. The pulmonary metastasis was spontaneous in one case.

Abstract
A report is made of a unique combination of occurrences of primary intraspinal epidural and subdural meningiomas and primary subcutaneous meningioma in the cervical region of a 15-year-old boy. The subcutaneous meningioma was detected at birth. Review of 92 recorded cases of primary dermal meningiomas revealed that they tended to occur in young patients, with an average age of 34 years for both sexes. The female-to-male ratio was 4:5. Most cutaneous meningiomas occurred in the head and neck, and the scalp was the most common site.

Abstract
Approximately 1% of meningiomas arise in extradural sites. Intradiploic meningiomas form only a very small proportion of this number. They tend to occur in young patients. The CT and MRI appearances, although unusual, may be characteristic of the condition. We present two cases and describe the CT and MR appearance; the latter has not previously been described.

Abstract
Four cases of primary intraosseous meningiomas were seen among 373 cases of intracranial meningiomas operated upon in the Neurosurgical Clinic of the Krankenhaus Nordstadt, Hannover, FRG between January 1978 and December 1988. These 4 cases represent 1% of all intracranial meningiomas. Patients' age ranged between 21 and 66 years; 2 were females and 2 males. Presenting symptoms were localized orbital pain in 1 case, protrusion of the eye in 1 patient, pain in the orbit and forehead and protrusion of the eye in 1 patient, and peripheral facial palsy in 1 case. Symptoms lasted between 3 and 10 years. Two tumours were in the bony orbit, 1 in the bony orbit and in the frontal bone and 1 in the temporal bone. All tumours were surgically completely removed. All patients are clinically and computer tomography free of tumour 1 to 8 years after the operation.

Abstract
Extracranial paranasal spread of meningiomas is uncommon. We describe the management of four cases, all of which first presented to an oto-rhino-laryngologist for an opinion. We suggest that greater use of modern imaging techniques could lead to earlier diagnosis. The natural history of extracranial spread is relatively benign but the management of regrowth of residual disease is difficult. We therefore suggest radical surgery in the first instance provided that the patients general health and configuration of the tumour allow.

Abstract
We studied 5 primary cutaneous meningiomas. All were congenital. Four were nodules or plaques on the scalp, and one was a lumbar polyp. Two were alopecic. A skull defect was present deep to one lesion, and the lumbar polyp was attached to dura. The tumors were concentrated in the subcutis, where strands of meningocytes were embedded in dense collageous tissue. Meningocytes wrapped around collagenous fibers, producing "collagen bodies". These formed the nidus for calcification that included psammoma bodies. Meningocytes also dissected between collagenous fibers, creating anastomosing spaces that mimicked a vascular tumor. Meningothelial-lined clefts, several milimeters in length, were present in 4 cases. Two lesions extended through dermal defects into the superficial dermis, where adnexa were reduced or absent. The meningocytes contained vimentin and epithelial membrane antigen. They lacked cytokeratin, S100 protein, and endothelial markers. The meningothelial lesions described herein lack the nodular and sheet-like growth patterns that typify meningiomas of the central nervous system and most primary ectopic meningiomas, including some that develop within the skin. They appear closely related to meningoceles and should be viewed as developmental abnormalities rather than neoplasms. The term "rudimentary meningocele" seems appropriate for these lesions.

Abstract
Meningiomas are the most common benign intracranial neoplasms, and although the otolaryngologist rarely sees these lesions, he or she may encounter them in surgery of the skull base. Surgical removal is the primary treatment modality for these meningiomas. To avoid recurrent disease, the best initial therapy is the most extensive procedure that can reasonably be effected. Chemotherapy and irradiation therapy have, at best, only limited roles in treatment.

Abstract
Extracranial meningiomas are most often due to extension from an intracranial primary and less so from meningocytic cells found with arachnoid clusters or modified mesenchymal cells. The most common presentation of all forms is cutaneous, either primary or secondary. Orbital, paranasal, temporal bone and oral presentations follow in that order.

Head and neck meningiomas are primarily intracranial neoplasms; they rarely present in extracranial locations. Two cases of meningiomas in the paranasal sinuses and seven cases in the temporal bone are described. The pathology, pathogenesis, clinical evaluation, and therapy are discussed. It is stressed that intracranial components of such meningiomas be sought and, as appropriate, treated.

Abstract
A meningioma demonstrating unusual anatomical and clinical manifestations is described. This intracranial tumor originated in the petrous region and extended into the neck, the patient remaining neurologically asymptomatic for nearly 2 years. The radiological features of this tumor as well as a review of the pertinent literature are presented.

Abstract
A patient is presented with findings of separate intracranial and extracranial meningiomas, each of a different histologic type. A calcified fibrous meningioma, with secondary psammomatous features, presented as a left neck mass associated with hoarseness, dysphagia, a unilateral facial weakness and hearing loss. A noncalcified asymptomatic intracranial syncytial meningioma was discovered in the left frontal lobe after computerized tomographic and angiographic study of the cranial contents. The origin of the extracranial meningioma producing multiple unilateralcranial nerve disturbances and serous otitis media is discussed. The noncontiguous tumors in this patients are felt to have separate origins, with the extracranial lesion most likely arising in the temporal bone.

Abstract
Meningiomas involving the temporal bone are very rare. Until 1964, only 39 cases had been reported in the world literature. Most series reported are very small and a physician is unable, based on his own experience, to acquire a sufficient knowledge about this entity and may raise serious doubts regarding the diagnosis and management of these tumors. In the past nine years the author has encountered five cases of meningiomas involving the temporal bone. This became a stimulus for a thorough research of the world literature of meningiomas in general, with emphasis on temporal bone involvement. Nine more cases were collected from cooperative physicians with whom the author has been associated. These 14 cases are the clinical material analysed in this study. This thesis is divided into three sections: 1. Exhaustive review of the world literature on meningiomas with emphasis on involvement of the temporal bone. 2. A detailed presentation and discussion of the clinical material stressing the importance of the newer diagnostic methods available and the most modern microsurgical techniques used in otological and neurological surgery procedures, applied to the treatment of those lesions. A light microscopic histopathological study of all cases reported is presented. Electronmicroscopy demonstrates the true intracellular nature of an atypical, recurrent meningioma occurring in a child. 3. A critical evaluation of the cases presented and the value of the diagnostic and therapeutic methods applied in this series of patients are here analysed. Conclusions are then drawn based on the experience and knowledge accumulated in this study. The histopathological diagnosis of meningiomas sometimes is difficult. Probably those tumors involve the temporal bone more commonly than has been reported in the literature. Some of these lesions probably are being misdiagnosed as chemodectomas or other neoplasias. Computerized axial tomography, particularly applied to the diagnosis of brain lesions, is the major break-through of recent modern medicine. A noninvasive technique, when used with contrast enhancement, offers great diagnostic possibilities. Early diagnosis of meningiomas and their complete surgical excision are the key factors necessary for a successful result with a good prognosis and a low recurrence rate. Although these tumors are classically considered radioresistant, radiotherapy may play a role in the treatment of incompletely excised lesions or in patients of a poor surgical risk. Further experiences and time will probably lead to more definite conclusions regarding the role of radiation therapy or the combined surgical and postoperative radiation treatment. Of all brain tumors, meningiomas offer the best prognosis.

Abstract
Meningiomas localized within the middle ear and mastoid which have no intracranial component are rare tumors. Three patients with meningiomas which were thought to involve only the middle ear were treated surgically, were followed for two to six years and were thought to have been cured. However, when computerized axial tomography became clinically available, these patients were examined using this radiographic technique. Unexpectedly, all three patients were found to have a large intracranial meningiomatous extension. A review of the literature reveals only 13 primary meningiomas; these case reports are summarized. It was noted that definitive tests for an intracranial extension of the meningioma were performed in only 2 of the 13 cases. Therefore, in view of our recent clinical experience, it is recommended that a patient presenting with a middle ear meningioma should have a computerized axial tomographic examination of the head to detect the possible presence of a clinical silent intracranial involvement.
