“…The ratio of male‐to‐female incidence is 40:35, and the age distribution ranges from 2 to 84 years in previous reports with detailed data. To date 110 cases of RM in 40 articles have been reported . The most common locations were convexity (25 of 74), anterior or middle cranial fossa (10 of 74), posterior cranial fossa (13 of 74) and falx or parasagittal sinus (16 of 74).…”

Meningiomas are the most common primary intracranial tumors. They are usually benign and slowly growing; however, they may show histologically malignant features categorizing them into grade II or III of World Health Organization (WHO) classification. Rhabdoid meningioma (RM) is an uncommon meningioma variant categorized as WHO grade III. The clinical course of RM is determined by local recurrences, invasion of adjacent brain and/or dura, widespread leptomeningeal dissemination, remote metastases and fatal clinical outcome. Herein we report a case with recurrent aggressive left occipital parasagittal region RM in which the patient initially declined radiation treatment. The tumor was resected four times in 5 years. Histopathological examination revealed a rhabdoid meningioma with metaplastic, papillary and chordoid differentiation. Six months after her fourth operation the patient died of progressive disease. RM is a rare subtype of malignant meningioma and the role of different adjuvant therapeutic options are still unknown. Clinical presentation, radiological features and pathologic findings of this uncommon tumor are discussed.

“…According to the literature, most rhabdoid meningiomas grow rapidly and aggressively and have a very poor prognosis. [14891112] Radiologic presentations are highly variable, and there have been reports of rhabdoid meningioma presenting as a cystic lesion and as intraventricular tumor. There are no sensitive radiologic features to distinguish this variant from other types of meningioma.…”

Background:Rhabdoid meningioma exhibits high mitotic activity, anaplasia, and increased markers of cell proliferation. Here we describe a rhabdoid meningioma with a pattern of growth extending into the subarachnoid space and filled the cortical sulci.Case Description:A 72-year-old woman presented with headache and was admitted to our hospital. Neurologic and physical examinations revealed no abnormalities. Contrast-enhanced axial T1-weighted images showed a well-enhanced, dural-based mass compressing the right temporal and frontal lobes, and extending into the sylvian cistern and filling the cortical sulci. The patient underwent partial resection and the histologic findings demonstrated rhabdoid meningioma.Conclusion:Although this type of tumor is known to be aggressive in its growth, extension into the adjacent cisternal space and the filling of the cortical sulci are rare. The combination of histologic anaplasia with the highest reported proliferation rate, loss of cohesion of neoplastic cells, and the location of the tumor led to the unique growth pattern.

“…First, we performed a deep review of RM cases previously reported in the literature between 1998 and 2021 [ 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 ]. A total of 305 RM cases were identified, including adults and children or adolescents under the age of 18 years.…”

Rhabdoid meningiomas (RM) shows heterogeneous histological findings, and a wide variety of chromosomal copy number alterations (CNA) are associated with an unpredictable course of the disease. In this study, we analyzed a series of 305 RM samples from patients previously reported in the literature and 33 samples from 23 patients studied in our laboratory. Monosomy 22-involving the minimal but most common recurrent region loss of the 22q11.23 chromosomal region was the most observed chromosomal alteration, followed by losses of chromosomes 14, 1, 6, and 19, polysomies of chromosomes 17, 1q, and 20, and gains of 13q14.2, 10p13, and 21q21.2 chromosomal regions. Based on their CNA profile, RM could be classified into two genetic subgroups with distinct clinicopathologic features characterized by the presence of (1) chromosomal losses only and (2) combined losses and gains of several chromosomes. The latter displays a higher frequency of WHO grade 3 tumors and poorer clinical outcomes.
