“…Meningiomas are the most frequent type of brain tumor, accounting for 37.6% of primary brain tumors, with an adjusted yearly incidence of ~8.3 per 100,000 individuals in the USA ( 1 , 6 ). Although multiple risk factors have been identified, the majority of meningiomas develop spontaneously and are of unknown etiology ( 7 ).…”

Meningiomas constitute the most common extra-axial tumor of the central nervous system and can have a wide-ranging manifestation of imaging. There are several types of unusual depictions depicted with the magnetic resonance imaging (MRI) of meningiomas that have been established thus far. It is thus crucial for the reporting radiologist or neurosurgeon to have an in-depth knowledge of their variable manifestations in order to be able to differentiate these neoplasms from the numerous tumors that can mimic their appearance. Meningioma is frequently challenging to diagnose when imaging variants are present. Nevertheless, a number of unusual histological variants have imaging or clinical features which are related to typical meningiomas and, in numerous cases, these require specific surgical management. The present study describes 7 cases of meningiomas, which were either simple atypical, unusual gigantic extracranial intracranial parasagittal, or not visible meningiomas. These uncommon and atypical imaging variants of meningiomas are described herein in an aim to underline their various potential presentations.

“…Meningiomas account for the second most frequent primary central nervous system tumor in adults (1). Despite considerable progress in current therapies, microsurgical resection is considered the treatment of choice for a number of patients with meningiomas (2)(3)(4)(5)(6).…”

Factors related to morbidity and mortality of meningiomas resection‑associated venous thromboembolism (Review)

et al. 2023

Patients undergoing intracranial meningioma removal have been reported to have an increased risk of venous thromboembolism (VTE). The present study aimed to study meningioma operations and ascertain rates of postoperative VTE more closely and to find out the associated parameters with VTE-related morbidity and mortality in meningioma patients following resection. This meta-analysis included articles involving meningiomas surgery and postoperative VTE [thromboembolic complications: deep venous thrombosis (DVT) and pulmonary embolism (PE)] published in full-text form between January 1980 and January 2021). Collected variables included: First author name, study period covered, publication year, total number of patients and age, number of males, surgical duration, body mass index (BMI), tumor location, proliferation marker for human tumor cells Ki-67 and VTE-related morbidity and mortality. After the initial search and applying all exclusion and inclusion criteria, five articles were left in the final article pool. The total number of patients was 6,505 who underwent surgery for meningiomas and 299 (4.5%) revealed postoperative VTE. The final results showed no potentially significant difference between the total sample and the postoperative VTE group in tumor location and proliferation marker Ki-67 for human cells. By contrast, the results of the analysis for surgical duration and BMI showed a statistically significant difference. Patients who had experienced open surgery for meningiomas were associated with postoperative VTE. Furthermore, surgical duration and BMI were statistically significant VTE-related parameters in patients who underwent meningioma surgery, showing an association with VTE-related morbidity and mortality.

A 7 yr old female spayed Chihuahua-terrier mix was presented for a progressive dry, hacking cough over 9 mo, with dyspnea aggravated by eating and drinking. Computed tomography of the skull revealed a large mineral attenuating mass associated with the left skull base, without intracranial involvement. A modified ventral paramedian hypophysectomy approach along the medial aspect of the left ramus was used to approach the base of the skull. Ninety percent of the mass was debulked via high-speed pneumatic burr. Histopathology was consistent with hyperostosis originating from a primary extracranial meningioma (ECM), with the tissue staining positive for vimentin and negative for cytokeratin. The patient was symptom free for 9 mo before clinical signs returned because of tumor recurrence and was euthanized 11 mo postoperation because of diminished quality of life. ECM is uncommonly reported in the dog, and to the authors’ knowledge has not previously been reported with hyperostosis or located along the skull base at the level of the tympanic bulla. Additionally, although hyperostosis predominantly occurs as diffuse bone thickening adjacent to a meningioma, proliferative focal hyperostosis is uncommon. Given the findings in this patient, ECM should be considered as a differential diagnosis for osseous skull base masses.
