Differentiating from other skull base tumors based on radiologic findings is difficult due to nonspecific features. PSP has a better prognosis after surgical resection and adjuvant radiotherapy, unless the tumor progresses to multiple myeloma (MM). Nonetheless, 50\u201360% progress to MM within a median time of 2 years. Gross total resection (GTR) for PSP is controversial for improving overall survival. However, if the lesion is easily accessible, for example, nonskull base lesion, GTR is still advocated.<\/jats:p>\n<\/jats:sec>\n\nCase Description: <\/jats:title>\nA 67-year-old male patient presented with right occipital neuralgia and diplopia in the last year. Neurological examination revealed mild abducens paresis on the right side. Brain MRI scan showed a large petroclival bony extradural mass lesion on the right side, with homogeneous enhancement, extending from the dorsum sellae to the ipsilateral occipital condyle and involving the petrous carotid artery. Brain CT scan revealed an osteolytic lesion without intratumoral calcifications, sclerotic border, or periosteal reaction. Anterior petrosal approach was performed and GTR was achieved. The patient had good postoperative outcome and improvement of symptoms. Postoperative MRI revealed GTR. Total body imaging work-up and immunohistochemistry confirmed PSP.<\/jats:p>\n<\/jats:sec>\n\nConclusion: <\/jats:title>\nAlthough the extent of resection in the outcome is controversial, maximal safe resection of skull base PSP should be considered to improve symptoms and quality of life.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_325_2022","type":"journal-article","created":{"date-parts":[[2022,5,15]],"date-time":"2022-05-15T12:56:21Z","timestamp":1652619381000},"page":"201","update-policy":"http:\/\/dx.doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Anterior petrosal approach for petroclival solitary plasmacytoma"],"prefix":"10.25259","volume":"13","author":[{"given":"Jos\u00e9 Orlando","family":"de Melo Junior","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Paulo Niemeyer State Brain Institute, Rio de Janeiro,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luiz Ant\u00f4nio da Silva","family":"Lavradas Junior","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, S\u00e3o Jos\u00e9 Hospital, Crici\u00fama,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Alberto","family":"Landeiro","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Ant\u00f4nio Pedro University Hospital, Fluminense Federal University, Niter\u00f3i, Brazil."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2022,5,13]]},"reference":[{"key":"10.25259\/SNI_325_2022\/ref-1","doi-asserted-by":"crossref","first-page":"118","DOI":"10.1186\/1471-2407-6-118","article-title":"Prognostic factors in solitary plasmacytoma of the bone: A multicenter rare cancer network study","volume":"6","author":"Knobel","year":"2006","journal-title":"BMC Cancer"},{"key":"10.25259\/SNI_325_2022\/ref-2","doi-asserted-by":"crossref","first-page":"263","DOI":"10.1007\/s11060-019-03089-z","article-title":"Clinical features, radiological profiles, and surgical outcomes of primary intracranial solitary plasmacytomas: A report of 17 cases and a pooled analysis of individual patient data","volume":"142","author":"Ma","year":"2019","journal-title":"J Neurooncol"},{"key":"10.25259\/SNI_325_2022\/ref-3","doi-asserted-by":"crossref","first-page":"61","DOI":"10.1055\/s-0035-1560047","article-title":"Plasmacytoma of the skull base: A meta-analysis","volume":"77","author":"Na\u2019ara","year":"2016","journal-title":"J Neurol Surg B Skull Base"},{"key":"10.25259\/SNI_325_2022\/ref-4","doi-asserted-by":"crossref","first-page":"210","DOI":"10.1016\/j.ijrobp.2005.06.039","article-title":"Outcomes and patterns of failure in solitary plasmacytoma: A multicenter rare cancer network study of 258 patients","volume":"64","author":"Ozsahin","year":"2006","journal-title":"Int J Radiat Oncol Biol Phys"},{"key":"10.25259\/SNI_325_2022\/ref-5","first-page":"1039","article-title":"Association between intracranial plasmacytoma and multiple myeloma: Clinicopathological outcome study","volume":"49","author":"Schwartz","year":"2001","journal-title":"Neurosurgery"},{"key":"10.25259\/SNI_325_2022\/ref-6","doi-asserted-by":"crossref","first-page":"717","DOI":"10.1111\/j.1365-2141.2004.04834.x","article-title":"Guidelines on the diagnosis and management of solitary plasmacytoma of bone and solitary extramedullary plasmacytoma","volume":"124","author":"Soutar","year":"2004","journal-title":"Br J Haematol"}],"container-title":["Surgical Neurology International"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/surgicalneurologyint.com\/anterior-petrosal-approach-for-petroclival-solitary-plasmacytoma\/","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/anterior-petrosal-approach-for-petroclival-solitary-plasmacytoma\/","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,5,15]],"date-time":"2022-05-15T12:56:25Z","timestamp":1652619385000},"score":1,"resource":{"primary":{"URL":"http:\/\/surgicalneurologyint.com\/surgicalint-articles\/anterior-petrosal-approach-for-petroclival-solitary-plasmacytoma\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,5,13]]},"references-count":6,"alternative-id":["10.25259\/SNI_325_2022"],"URL":"https:\/\/doi.org\/10.25259\/sni_325_2022","relation":{},"ISSN":["2152-7806"],"issn-type":[{"value":"2152-7806","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,5,13]]},"article-number":"201"}}
