It has unique Alcian blue stromal staining and distinctive cellular interdigitations, junctional complexes, and nucleolar pseudoinclusions on ultrastructural pathology that help to distinguish it from other meningioma variants. The authors describe the case of a rare left middle fossa, extraaxial myxoid meningioma in a 50-year-old woman to emphasize the important histological characteristics and observations essential for making a precise diagnosis. To their knowledge this is the seventh reported case of a myxoid meningioma in the literature and the sixth case in an adult; however, it is the first reported instance of myxoid meningioma in a patient presenting with intratumoral hemorrhage.<\/jats:p>","DOI":"10.3171\/2011.12.jns111020","type":"journal-article","created":{"date-parts":[[2012,1,20]],"date-time":"2012-01-20T15:28:40Z","timestamp":1327073320000},"page":"861-865","source":"Crossref","is-referenced-by-count":23,"title":["Myxoid meningioma: a rare metaplastic meningioma variant in a patient presenting with intratumoral hemorrhage"],"prefix":"10.3171","volume":"116","author":[{"given":"Khaled M.","family":"Krisht","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tamer","family":"Altay","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"William T.","family":"Couldwell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-jns111020","series-title":"Ultrastruct Pathol","first-page":"367","article-title":"Myxoid meningioma","volume":"14","author":"B\u00e9gin","year":"1990"},{"key":"b2-jns111020","series-title":"J Neurosurg","first-page":"473","article-title":"Spontaneous intracranial meningioma bleeding: clinicopathological features and outcome","volume":"103","author":"Bosnjak","year":"2005"},{"key":"b3-jns111020","series-title":"Neuropathology","first-page":"708","article-title":"Intraventricular metaplastic meningioma in a child: case report and review of the literature","volume":"29","author":"Dulai","year":"2009"},{"key":"b4-jns111020","series-title":"Acta Neuropathol","first-page":"80","article-title":"Myxoid meningioma: histochemistry and electron microscopy","volume":"68","author":"Harrison","year":"1985"},{"key":"b5-jns111020","series-title":"Jpn J Magn Reson Med Sci","first-page":"73","article-title":"Intracranial myxoid meningioma with marked hyperintensity on T2-weighted images","volume":"23","author":"Ishikawa","year":"2003"},{"key":"b6-jns111020","series-title":"Pathol Int","first-page":"53","article-title":"Pericellular deposition of basement membrane material in myxoid meningioma: immunohistochemical evidence for unbalanced production of type IV collagen and laminin","volume":"48","author":"Kimura","year":"1998"},{"key":"b7-jns111020","series-title":"Brain Pathol","first-page":"255","article-title":"The new WHO classification of brain tumours","volume":"3","author":"Kleihues","year":"1993"},{"key":"b8-jns111020","series-title":"Cell Tissue Res","first-page":"563","article-title":"Development of the basal lamina in xenografted human carcinomas: an ultrastructural and immunohistochemical study","volume":"266","author":"K\u00f6pf-Maier","year":"1991"},{"key":"b9-jns111020","series-title":"WHO Classification of Tumours: Pathology and Genetics of Tumours of the Nervous System","first-page":"176","article-title":"Meningiomas","author":"Louis","year":"2000"},{"key":"b10-jns111020","series-title":"Acta Neurochir (Wien)","first-page":"129","article-title":"Meningiomas with haemorrhagic onset","volume":"110","author":"Mart\u00ednez-Lage","year":"1991"},{"key":"b11-jns111020","series-title":"Neuropathology","first-page":"243","article-title":"Chordoid meningioma: rare variant of meningioma","volume":"24","author":"Ozen","year":"2004"},{"key":"b12-jns111020","series-title":"WHO Classification of Tumours of the Central Nervous System","first-page":"164","article-title":"Meningiomas","author":"Perry","year":"2007"},{"key":"b13-jns111020","series-title":"Am J Surg Pathol","first-page":"769","article-title":"Lipomatous meningioma: a clinicopathologic study of 18 cases with special reference to the issue of metaplasia","volume":"25","author":"Roncaroli","year":"2001"},{"key":"b14-jns111020","series-title":"Am J Surg Pathol","first-page":"1182","article-title":"Combined morphologic and karyotypic study of 59 atypical lipomatous tumors.
