These tumors can develop in various anatomical sites, including the central nervous system, presenting as an extra-axial tumor affecting the meninges or the ependyma. Diagnosis is challenging due to its resemblance to other intracranial tumors such as meningiomas.<\/jats:p>\n                  <jats:p>Case Description We present the case of a 17-year-old male with intermittent left frontotemporal headache, diplopia during horizontal gaze, and proptosis of the left eye. During the imaging evaluation, an extra-axial tumor was observed, suggesting a meningothelial lesion of the left sphenoid wing. The patient had no previous hematological disease. Tumor resection was performed using an orbitozygomatic approach. After 2 months, the patient had recurrence of the lesion associated with spontaneous epistaxis and leucocytosis and thrombocytopenia. Bone marrow aspirate biopsy and histopathology results were consistent with myeloid sarcoma.<\/jats:p>\n                  <jats:p>Conclusion Intracranial myeloid sarcomas mimic meningiomas, metastases, lymphomas, and even Ewing\u2019s sarcoma, making it difficult to suspect myeloid sarcoma in a patient without prior hematologic disease. Surgery aids in diagnosis through biopsy or reduces the volume effect that could cause neurological deficit.<\/jats:p>","DOI":"10.1055\/a-2914-7953","type":"journal-article","created":{"date-parts":[[2026,7,15]],"date-time":"2026-07-15T23:11:20Z","timestamp":1784157080000},"page":"e124-e129","source":"Crossref","is-referenced-by-count":0,"title":["Intracranial Myeloid Sarcoma as the First Manifestation of Acute Monoblastic Leukemia"],"prefix":"10.1055","volume":"87","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5317-9591","authenticated-orcid":false,"given":"Bernardo","family":"Ramos Fraga","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, UMAE Hospital de Especialidades No. 25, Centro Medico Nacional Noreste, Instituto Mexicano del Seguro Social, Nuevo Leon, M\u00e9xico","place":["Monterrey"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Francisco","family":"Tovar Gaucin","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, UMAE Hospital de Especialidades No. 25, Centro Medico Nacional Noreste, Instituto Mexicano del Seguro Social, Nuevo Leon, M\u00e9xico","place":["Monterrey"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vicente Jonathan","family":"S\u00e1nchez Coronado","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, UMAE Hospital de Especialidades No. 25, Centro Medico Nacional Noreste, Instituto Mexicano del Seguro Social, Nuevo Leon, M\u00e9xico","place":["Monterrey"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2339-0315","authenticated-orcid":false,"given":"Pablo Josafat","family":"Avalos Montes","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, UMAE Hospital de Especialidades No. 25, Centro Medico Nacional Noreste, Instituto Mexicano del Seguro Social, Nuevo Leon, M\u00e9xico","place":["Monterrey"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia Judith","family":"Hern\u00e1ndez Mart\u00ednez","sequence":"additional","affiliation":[{"name":"UMAE Hospital de Especialidades No. 25, Centro M\u00e9dico Nacional Noreste, Instituto Mexicano del Seguro Social, Nuevo Le\u00f3n, M\u00e9xico","place":["Monterrey"],"department":["Department of Neuropathology"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-2927-2929","authenticated-orcid":false,"given":"Jos\u00e9 Ram\u00f3n","family":"Olivas Campos","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, UMAE Hospital de Especialidades No. 25, Centro Medico Nacional Noreste, Instituto Mexicano del Seguro Social, Nuevo Leon, M\u00e9xico","place":["Monterrey"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2026,7,27]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-319-26587-2_86-1","volume-title":"Malignant and benign extramedullary tumor-forming myeloid proliferations","author":"A Zimmermann","year":"2016"},{"issue":"05","key":"ref2","doi-asserted-by":"crossref","first-page":"309","DOI":"10.1177\/2040620711410774","article-title":"Myeloid sarcoma: current approach and therapeutic options","volume":"2","author":"B Avni","year":"2011","journal-title":"Ther Adv Hematol"},{"issue":"04","key":"ref3","doi-asserted-by":"crossref","first-page":"271","DOI":"10.1177\/106689690301100404","article-title":"Myeloid sarcoma: clinical and morphologic criteria useful for diagnosis","volume":"11","author":"J Audouin","year":"2003","journal-title":"Int J Surg Pathol"},{"issue":"12","key":"ref4","doi-asserted-by":"crossref","first-page":"3607","DOI":"10.1007\/s00381-023-06016-w","article-title":"Intracranial myeloid sarcoma as the first presentation of acute myeloid leukemia and literature review","volume":"39","author":"S Kumarasamy","year":"2023","journal-title":"Childs Nerv Syst"},{"issue":"03","key":"ref5","doi-asserted-by":"crossref","first-page":"350","DOI":"10.1080\/02688697.2020.1759782","article-title":"Isolated intracranial myeloid sarcoma: report of a case and review of the literature","volume":"37","author":"F R Barbieri","year":"2023","journal-title":"Br J Neurosurg"},{"issue":"02","key":"ref6","doi-asserted-by":"crossref","first-page":"135","DOI":"10.1016\/S0303-8467(86)80010-5","article-title":"Intracerebral chloromas.
