Zhang DB, Chen T. Primary pulmonary meningioma: A case report and review of the literature. World J Clin Cases 2022; 10:4196-4206. [PMID: 35665099 PMCID: PMC9131207 DOI: 10.12998/wjcc.v10.i13.4196] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 01/28/2022] [Accepted: 03/16/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Primary pulmonary meningioma (PPM) is a rare disease that is usually benign. The most common presentation of PPM is isolated pulmonary nodules or masses, so the disease can mimic any other lung tumor on imaging, especially lung cancer or metastasis.
CASE SUMMARY A 47-year-old asymptomatic woman presented with a well-defined, lobulated pulmonary mass with calcification in the left lower lobe. The mass measured 69 mm × 57 mm × 61 mm and was found during a chest computed tomography (CT) performed for physical examination. Contrast-enhanced CT and positron emission tomography (PET)/CT revealed mild enhancement of the mass, with accumulation of 18-fluoro-2-deoxy-D-glucose (18F-FDG). Transbronchial biopsy suggested a provisional diagnosis of low-grade neuroendocrine tumor. Subsequent enhanced head magnetic resonance imaging revealed no positive lesions. An open cuff resection of the left lower lobe and wedge resection of the lingual segment were performed. Histopathological and immunohistochemical examination revealed that the mass was a PPM.
CONCLUSION PPM should be considered in the differential diagnosis of isolated pulmonary masses found incidentally on CT and should be diagnosed based on a combination of radiological and histological features. Surgical resection is currently the main treatment strategy. No recurrence of benign PPMs has been reported after complete resection.

Primary pulmonary meningiomas: report of two cases and review of the literature. Pathol Res Pract 2020; 216:153232.

Abstract
BACKGROUND Meningiomas rarely occur outside the skull, and primary pulmonary meningiomas (PPMs) are more rare. Only a few cases have been reported in the literature. The clinicopathological characteristics are not clear and it is easy to be misdiagnosed, so it is very important to master its diagnosis and differential diagnosis. METHODS We report two women with primary pulmonary meningioma. At the time of physical examination, the small solitary pulmonary nodules were detected on chest radiograph, and wedge resection was performed by Video-assisted Thoracoscope Surgery(VATS), and histologic evaluation showed that the lesions were benign PPMs. The clinicopathological features, immunophenotype and differential diagnosis of PPMs were analyzed, with a review of the cases published in the literature. RESULTS The study group comprised of 40 patients, 14 males and 26 females. The median age was 56.5 years (range 18-108). Thirty patients who underwent routine screening studies were asymptomatic but had a pulmonary nodule detected on chest X-ray. Nine patients had respiratory symptoms. Only 1 patient had non-specific symptoms. Most of the PPMs were benign, only 3 cases were malignant. Benign PPMs ranged from 0.6 cm to 6 cm in diameter (median 2 cm). The 3 malignant PPMs were 5 cm, 6.5 cm and 15 cm in diameter. The prognosis of benign PPM resection is good, with almost no recurrence or metastasis. But the two of three malignant PPMs relapsed. CONCLUSIONS PPM is very rare. It needs to be diagnosed by combining histology and immunohistochemistry. Diseases that need to be identified include spindle cell mesothelioma, spindle cell thymoma, spindle cell carcinoma, metastatic tumor, etc.

Abstract
Primary pulmonary meningiomas are rare and their occurrence has been reported only sporadically. The diagnosis of such tumors should be accepted only after the presence of an intracranial or intraspinal meningioma has been excluded. The morphological and immunohistochemical features are similar to those of intracranial meningiomas. A case of primary pulmonary meningioma along with a review of the literature and discussion of other lesions in the differential diagnosis of this rare neoplasm are here presented.

Abstract
Minute pulmonary meningothelial-like nodules (PMNs) are asymptomatic, small nodules that are occasionally detected in surgical or autopsy specimens. Recent improvements in tumor imaging and the increased use of computed tomography (CT) scans of the chest have led to the early detection of these pulmonary nodules in various clinical settings, often before surgery or health examinations. However, large PMNs have rarely been observed. In this study, we report a patient with a large PMN, which was almost identical to so-called ‘primary pulmonary meningioma’. A CT scan of his chest revealed a small, well-circumscribed nodule. Immunohistochemical analysis of the tumor revealed that the tumor cells were positive for CD56, epithelial membrane antigen, and progesterone receptor. Given the similarity of these results to the staining pattern of minute PMNs in previous reports, we suggest that the primary pulmonary meningiomas reported to date are, in fact, a giant form of PMN.

Abstract
Pulmonary metastases of benign meningiomas are extremely rare. The case of a 34-year-old man with bilateral parasagittal meningioma who developed pulmonary metastases is described. The meningioma was an enormous hypervascular tumor with invasion of the superior sagittal sinus. The tumor was resected completely and histologically diagnosed as transitional meningioma. The Ki-67 labeling index was 5%. Four months after operation, the patient subsequently developed bilateral multiple lung lesions later identified as metastases. The lung lesions were partially removed surgically and histologically diagnosed as meningothelial meningioma WHO grade I. The Ki-67 labeling index was 2%. The histological findings demonstrated that the tumor occupied the arterial lumen and the perivascular space, suggesting that pulmonary tumors might metastasize via the vascular route. The histopathological features and mechanisms of metastasizing meningiomas are reviewed and discussed.

Abstract
Primary pulmonary meningioma (PPM) is a rare disease and usually presents as a solitary pulmonary nodule (SPN). These lesions are mostly benign, but malignant PPMs have been reported, and primary lung cancer or metastasis may be suspected on imaging. We report one case of benign PPM, with a review of 37 cases published in the literature. Diagnostic work-up included radiological chest study and in 3 cases positron emission tomography (PET) showing increased uptake, highly suspicious for malignancy. After exclusion of 13 cases lacking radiological studies of the central nervous system (CNS), 25 patients with radiological data and histological assessment confirming PPM were considered in the analysis. All patients underwent surgical resection except for 1 case with diagnosis at autopsy. Histological assessment revealed benign PPMs in 23 cases (including all 3 cases with positive PET) and malignant PPMs in 2 cases. No recurrence was observed in long-term follow-up of patients with benign PPMs, but the two malignant PPMs relapsed. PPM is an uncommon SPN, so that it can be misdiagnosed and its management unsuited. Indeed, 8 patients (32%) were overtreated with major thoracic surgical resection or with chemotherapy. When feasible, pulmonary wedge resection by video-assisted thoracic surgery (VATS) including intra-operative histological examination is the most suitable approach to determine the diagnosis and the volume of pulmonary resection.

Abstract
Meningiomas account for approximately 15% of all intracranial tumors and are the most common non-glial primary tumors of the central nervous system. Most meningiomas are benign neoplasms with characteristic imaging features. Primary extradural meningiomas account for only 1-2% of all meningiomas. They must be differentiated from intradural meningiomas with secondary extradural extension and/or metastases. The vast majority of extradural meningiomas are found in the skull or in the head and neck region. We report on an extremely rare case of primary extradural meningioma that was located in the scapula. The lesion was resected. Radiographic findings and pathologic features are discussed. To the best of our knowledge, this form of presentation of an extradural meningioma has not been previously described.

Abstract
Lung "metastases" of benign meningiomas are rarely described events of biological and clinical interest. We, here, report of a 70-year-old healthy woman found by CT scan to have multiple lesions, the two largest in the right lung on routine examination. Anamnesis revealed that the patient underwent a surgical resection of cerebral meningioma 12 years before. The larger lung lesion was a 3-cm node located in the right lung and was removed by wedge resection. Macroscopically, it showed well-defined borders, whitish colour and firm consistency; histologically, it was uniformly composed by spindle meningothelial cells arranged in fascicules including psammoma bodies. The morphological and immunohistochemical features of this lesion, together with the similarity with the original cerebral tumour and its indolent evolution, led to a final diagnosis of "benign" meningioma metastatic to the lung. Lung metastatic meningiomas may be a diagnostic challenge because of their unusual site of presentation and the possible confusion with primitive lung meningiomas or primary mesenchymal lung lesions. They represent a typical example of "benign" tumours that may implant to the lung similar to other tumours, definitely considered benign but reported to rarely present unusual secondary localization.

Abstract
Primary meningiomas of the lung are rare. Most pulmonary meningiomas are typical syncytial or transitional meningiomas with smaller numbers of fibrous-type tumors. Herein, we report an unusual pulmonary tumor with the microscopic, immunohistochemical, and ultrastructural characteristics of a chordoid meningioma. The tumor was composed of cords and fascicles of small- to medium-sized spindle and epithelioid cells with eosinophilic cytoplasm and round nuclei with finely dispersed chromatin. The tumor cells were surrounded by an abundant mucoid, vacuolated stroma. The periphery of the tumor was enveloped by a significant lymphoplasmacytic infiltrate. The neoplastic cells were positive for vimentin and epithelial membrane antigen only. The unusual morphology of the tumor caused significant diagnostic difficulties. The differential diagnosis included inflammatory myofibroblastic tumor, spindle cell myoepithelioma, and extraskeletal myxoid chondrosarcoma. To the best of our knowledge, this is possibly the first description of an extracranial or intrapulmonary chordoid meningioma.

Abstract
An example of extranodal follicular dendritic cell sarcoma (FDCS) presenting in the lung, a heretofore unreported site, is described. Macroscopically, a 9.5-cm, tan-white, dominant mass and multiple smaller parenchymal and pleural nodules were identified. Microscopically, the tumor was composed of spindled cells with uniform cytologic features arranged in short, intersecting fascicles and intermixed small lymphocytes and plasma cells. One of 4 peribronchial and hilar lymph nodes evaluated microscopically was focally involved by the process. Immunohistochemically, the neoplastic spindled cells expressed complement receptors CD21 and CD35 and low-affinity nerve growth factor receptor but did not express keratin (AE1/AE3 and CAM5.2), CD45 (leukocyte common antigen), CD20 (L26), S-100 protein, muscle-specific actin, or gp100 protein (HMB45). Ultrastructurally, the tumor cells have complex interdigitating cell surface processes and desmosomes. Epstein-Barr virus (EBV) was not detected in the tumor cells by in situ hybridization for EBV-encoded RNA or by polymerase chain reaction for viral DNA. FDCS should be considered in the differential diagnosis of any spindled-cell tumor with interspersed chronic inflammatory cells occurring in the lung. An immunohistochemical panel, including anti-CD21 and -CD35, can assist in its diagnosis, especially with small bronchial biopsy specimens. 2001 by W.B. Saunders Company.

Abstract
STUDY DESIGN Total excision of a large dumbbell cervicothoracic intra- and extraspinal meningioma that had grown into the posterior mediastinum is described. This excision involved a two-step neurosurgical-thoracosurgical procedure within a short interval. OBJECTIVES To document that the described laminectomy and thoracotomy techniques are adequate, safe, and effective for the treatment of this intra- and extraspinal meningioma lesion. SUMMARY OF BACKGROUND DATA The management of intra- and extraspinal dumbbell tumors is based on anecdotal reports of mostly neurinomas, and thus remains a controversial issue. Even large series of spinal meningiomas lack adequate information on how best to treat large cervicothoracic meningiomas. METHODS The authors have modified standard techniques used for resection of spinal and mediastinal tumors, respectively, adapting them for a large, invasive dumbbell meningioma in a 72-year-old lady. The patient initially underwent laminectomy and microsurgical excision of the intraspinal tumor portions encasing vascular structures. A week thereafter, a thoracotomy was performed, and the mediastinal tumor portions were removed completely. RESULTS Restitution was remarkably good. The patient, who had been unable to walk on her own, regained some mobility. At this writing, she was able to walk considerable distances without support. There was no evidence of tumor recurrence during a follow-up interval of 3 years. CONCLUSIONS The authors recommend a two-staged procedure for complete excision of a large spinal-thoracic meningioma. Even in elderly patients with major neurologic deficits, an impressive recovery can be achieved with such lesions.

Abstract
OBJECT Primary meningiomas arising outside the intracranial compartment (primary extradural meningiomas [PEMs]) are rare tumors. To develop a better understanding of these tumors and to establish a comprehensive classification scheme for them, the authors analyzed a series of patients treated at the M. D. Anderson Cancer Center (MDACC) and reviewed all cases reported in the English-language literature since the inception of the use of computerized tomography (CT) scanning. METHODS Clinical records, results of radiographic studies, and histological slides were reviewed for all cases of PEM at MDACC. Demographic features, symptoms, tumor location, histological grade, and patient outcome were assessed in all cases. A comprehensive literature search identified 168 PEMs in 142 patients reported during the CT era. These reports were also analyzed for common features. Tumors for both data sets were classified as purely extracalvarial (Type I), purely calvarial (Type II), and calvarial with extracalvarial extension (Type III). Type II and Type III tumors were further categorized as convexity (C) or skull base (B) lesions. The incidence of PEMs at MDACC was 1.6%, which was consistent with the rate reported in the literature. In both data sets, the male/female ratio was nearly 1:1. The most common presenting symptom was a gradually expanding mass. The age of patients at diagnosis of PEM was bimodal, peaking during the second decade and during the fifth to seventh decades. In all MDACC cases and in 90% of those reported in the literature the PEMs were located in the head and neck. The majority of tumors originated in the skull (70%). In the MDACC series and in the literature review, the majority (67% and 89%, respectively) of tumors were histologically benign. Although fewer PEMs were malignant or atypical (33% at MDACC and 11% in the literature), their incidence was higher than that observed for primary intracranial meningiomas. Distant metastasis was not a common feature reported for patients with PEMs (6% in the literature). Outcome data were available in 96 of the cases culled from the CT-era literature. The combination of the MDACC data and the data obtained from the literature demonstrated that patients with benign Type IIB or Type IIIB lesions were more likely to experience recurrence than patients with benign Type IIC or Type IIIC tumors (26% compared with 0%, p < 0.05). The more aggressive atypical and malignant tumors were associated with a statistically significant higher death rate (29%) relative to benign tumors (4.8% death rate, p < 0.004). CONCLUSIONS Defining a tumor as a PEM is dependent on the tumor's relation to the dura mater and the extent and direction of its growth. Classification of PEMs as calvarial or extracalvarial and as convexity or skull base lesions correlates well with clinical outcome.

Abstract
Fewer than 20 cases of primary pulmonary meningioma have been reported. Most of these cases have been histologically and clinically benign. We report an unusual case of primary pulmonary malignant meningioma with atypical histologic features and malignant behavior. A computed tomography scan of the head did not show evidence of tumor. The right upper lobe mass was resected and showed features of an atypical meningioma with loss of architectural pattern, mild nuclear pleomorphism, increased mitotic counts (up to 15 mitotic figures per 10 high power fields), and focally prominent nucleoli. Focally, cells with rhabdoid features were identified. The tumor's immunohistochemical and ultrastructural profiles were consistent with a meningioma. The tumor stained negative for estrogen and focally positive for progesterone receptors and had a MIB-1 labeling index (marker of cell proliferation) of 9.2%. Approximately 5 months after the initial resection, the patient experienced a tumor recurrence with multiple lymph node metastases, spread to the middle and lower lobes of the right lung, and metastasis to the diaphragm. Rarely, primary pulmonary meningiomas may present as high-grade malignant lesions.

Abstract
Two cases of primary cutaneous meningioma are described. A male and a female patient, aged 56 and 61 years, respectively, presented each with a solitary subepidermal nodule. The initial diagnosis was established in both patients by application of FNA biopsy. The subsequent histologic examination confirmed the cytologic diagnosis. Extensive investigation of the patients by computed tomography (CT) and nuclear magnetic resonance imaging (MRI) scans failed to reveal any primary meningioma of the neuraxis. Neurologic examination and routine laboratory test results were all normal. The microscopic features, immunocytological study and histology, which all gave a similar pattern to that seen in intracranial meningiomas, are discussed. Distinction from other cutaneous lesions that may be considered in the differential diagnosis is made. A brief review of the literature is also presented.

Abstract
Ten cases of benign primary pulmonary meningioma have been reported in the English literature. We describe herein an additional case of a benign meningioma arising in the lung showing comparable histologic features of sheets and whorls of epithelioid and meningothelial cells with numerous psammoma bodies. Immunohistochemistry showed that the tumor expressed vimentin and epithelial membrane antigen and was negative for keratin, CD34, glial fibrillary acidic protein, CAM 5.2 and S-100, in keeping with previously reported findings. Our review of the literature reveals similar clinical presentations and follow-up behavior and, where reported, similar electron microscopic and immunostaining features.

Abstract
Cutaneous meningeal tumors are rare and can pose a diagnostic problem. We present a case of a 12-year-old girl with a family history of von Recklinghausen's disease. The patient was asymptomatic until the age of 11, when she developed two lesions on the head, both diagnosed as plexiform neurofibroma. Subsequently, she presented with a subcutaneous nodule on the left posterior occipital scalp which was excised. On histology, the tumor was composed of spindle-shaped cells with diffuse and nested patterns. A whorled configuration of the cells, with occasional giant cells and psammoma bodies, was present. There was no evidence of connection between the tumor and the underlying tissues. Immunohistochemical studies were positive for epithelial membrane antigen, vimentin, and weakly for neuron-specific enolase. Cytokeratin, S-100 protein, and muscle markers were negative. Based on these features, the diagnosis of cutaneous meningioma was made. An MRI examination failed to detect any communication between the tumor site and the meninges; however, asymptomatic bilateral acoustic neuromas were identified. This case, besides being of interest as a primary cutaneous meningioma, also documents a unique combination of findings, i.e., plexiform neurofibroma, meningioma, and cerebellopontine acoustic neuromas, which should alert the clinician to a forme fruste presentation of von Recklinghausen's disease.

Abstract
We report a 53-year-old man with a solitary pulmonary nodule and signs of disease progression in chest films taken in the last year with lung metastasis from benign meningioma diagnosed by transthoracic puncture and aspiration. The rarity of this condition is discussed along with the need to include it as a differential diagnosis in patients with recurring meningioma even when the primary lesion is benign, given that early surgical resection of the metastasis resolves this complication.
