Intracranial Meningioma in Patients Age <35 Years: Evolution of the Disease in the Era of Human Immunodeficiency Virus Infection

Consensus core clinical data elements for meningiomas

BACKGROUND

With increasing molecular analyses of meningiomas, there is a need to harmonize language used to capture clinical data across centers to ensure that molecular alterations are appropriately linked to clinical variables of interest. Here the International Consortium on Meningiomas presents a set of core and supplemental meningioma-specific Common Data Elements (CDEs) to facilitate comparative and pooled analyses.

METHODS

The generation of CDEs followed the four-phase process similar to other National Institute of Neurological Disorders and Stroke (NINDS) CDE projects: discovery, internal validation, external validation, and distribution.

RESULTS

The CDEs were organized into patient- and tumor-level modules. In total, 17 core CDEs (10 patient-level and 7-tumour-level) as well as 14 supplemental CDEs (7 patient-level and 7 tumour-level) were defined and described. These CDEs are now made publicly available for dissemination and adoption.

CONCLUSIONS

CDEs provide a framework for discussion in the neuro-oncology community that will facilitate data sharing for collaborative research projects and aid in developing a common language for comparative and pooled analyses. The meningioma-specific CDEs presented here are intended to be dynamic parameters that evolve with time and The Consortium welcomes international feedback for further refinement and implementation of these CDEs.

Lung metastases from intracranial bleeding meningioma: A case report

RATIONALE

Meningioma is slow-growing benign neoplasm that derived from the meningothelial cells of the arachnoid mater, and it is the most common type of primary brain tumor. Although cases of extracranial metastatic meningioma have been reported previously, few cases have reported the concurrent occurrence of primary meningioma with intratumoral bleeding and lung metastases. Here we report a case of meningioma with concurrent intratumoral bleeding and lung metastases.

PATIENT CONCERNS

The patient was admitted to our hospital with sudden left limb paralysis combined with complaints of headache and dizziness.

DIAGNOSES

Histopathological results confirmed the lung metastases derived from intracranial bleeding meningioma.

INTERVENTIONS

The magnetic resonance imaging (MRI) of brain and computed tomography (CT) of brain and lung were performed.

OUTCOMES

CT and MRI of brain showed an intracranial mass associated with intratumoral hemorrhage. Then, multiple lung metastases were observed in the right lung via CT images. The intracranial mass was excised through craniotomy firstly, and a thoracoscopic biopsy was performed 1 month later. The patient was hospitalized again after 1 year because of suddenly epilepsy and received effective symptomatic treatment until symptoms were relieved. Then the patient is lost to follow-up.

LESSONS

When meningiomas occurred nearby venous sinuses with aggressive behavior, a careful whole-body examination is recommended in order to find distant metastasis as early as possible.
