The patient was an 84\u2010year\u2010old man with a convexity meningioma of the left frontal lobe. The tumor showed histopathological features of atypical meningioma suggestive of progression to anaplastic meningioma and contained a well\u2010circumscribed vascular lesion resembling a CM. The pathogenesis of the association of meningiomas with CM\u2010like vascular lesions is briefly discussed, and in the present case the vascular lesion is considered to represent an anomalous reactive proliferation of stromal blood vessels in an atypical meningioma.<\/jats:p>","DOI":"10.1111\/neup.70031","type":"journal-article","created":{"date-parts":[[2025,11,10]],"date-time":"2025-11-10T23:55:21Z","timestamp":1762818921000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cavernous Malformation\u2010Like Vascular Lesion Within an Atypical Meningioma: A Case Report"],"prefix":"10.1111","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7162-9293","authenticated-orcid":false,"given":"Masayuki","family":"Shintaku","sequence":"first","affiliation":[{"name":"Department of Pathology Kansai Medical University Hospital  Hirakata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuo","family":"Hashiba","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Kansai Medical University Hospital  Hirakata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masahiro","family":"Nonaka","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery Kansai Medical University Hospital  Hirakata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Katsunori","family":"Uchida","sequence":"additional","affiliation":[{"name":"Department of Pathology Kansai Medical University Hospital  Hirakata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koji","family":"Tsuta","sequence":"additional","affiliation":[{"name":"Department of Pathology Kansai Medical University Hospital  Hirakata Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,11,10]]},"reference":[{"volume-title":"Central Nervous System Tumours","year":"2021","author":"WHO Classification of Tumours Editorial Board","key":"e_1_2_11_2_1"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s004010051102"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000478-200403000-00013"},{"key":"e_1_2_11_5_1","first-page":"765","article-title":"A Rare Pattern of Angiogenesis in Meningiomas.
