Imaging survey revealed a right frontal lobe extra-axial mass with significant perilesional edema. The patient underwent a one-stage craniotomy for tumor removal. The pathology revealed collision brain tumors of clear cell atypical meningioma (WHO grade II) and glioblastoma. The patient had an uneventful postoperative recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical discussion:<\/jats:title>\n                    <jats:p>The mechanism behind collision brain tumors remains unclear, and some experts consider these tumors sporadic events. Further research is needed to optimize preoperative diagnosis and surgical strategy for collision brain tumor patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Surgeon should consider intracranial collision tumors when brain image indicated unusual perilesional edema of meningioma. Though there is no standard treatment for these patients, it seems one-staged surgical treatment is feasible. To our knowledge this is the first case of collision tumors with clear cell atypical meningioma (WHO grade II) and glioblastoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                  <\/jats:sec>","DOI":"10.1016\/j.ijscr.2022.107137","type":"journal-article","created":{"date-parts":[[2022,5,4]],"date-time":"2022-05-04T21:45:11Z","timestamp":1651700711000},"page":"107137","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":12,"title":["Collision brain tumor with atypical meningioma and glioblastoma"],"prefix":"10.1097","volume":"94","author":[{"given":"Mao-Shih","family":"Lin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chung-Hsin","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Se-Yi","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiung-Chyi","family":"Shen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-133-20260304","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1186\/s41016-016-0026-7","article-title":"Astrocytoma simultaneously present with meningioma-a report of two cases and review of the literature","volume":"2","author":"Hasimu","year":"2016","journal-title":"Chin.
