Osteoma at the petrous apex is a rare etiology of TN. Here, the authors present a case involving the co-occurrence of petrous osteoma and a vascular loop around the trigeminal nerve. Both exerted pressure or compression on the exit of the trigeminal nerve.<\/jats:p>\n <\/jats:sec>\n \n OBSERVATIONS<\/jats:title>\n A 46-year-old male presented with a 3-year history of persistent severe pain in the right side of his face. Magnetic resonance tomographic angiography of the trigeminal nerve revealed an abnormal signal in the right prepontine cistern, along with a vascular loop accompanying the right trigeminal nerve. A computed tomography scan of the skull indicated a nodular calcified density. The combined anterior transpetrosal approach for petrous osteoma and microvascular decompression (MVD) for the offending vessel were successfully performed. The patient was discharged without any complications or facial pain.<\/jats:p>\n <\/jats:sec>\n \n LESSONS<\/jats:title>\n Although extremely rare, TN simultaneously secondary to petrous osteoma and offending vessels should be considered in the diagnosis. In this case, the combined surgical removal of petrous osteoma and MVD for the offending vessels proved to be an effective treatment for TN secondary to osteoma and vascular compression.<\/jats:p>\n <\/jats:sec>","DOI":"10.3171\/case23518","type":"journal-article","created":{"date-parts":[[2023,12,4]],"date-time":"2023-12-04T18:54:11Z","timestamp":1701716051000},"source":"Crossref","is-referenced-by-count":5,"title":["Trigeminal neuralgia secondary to osteoma and vascular compression: illustrative case"],"prefix":"10.3171","volume":"6","author":[{"given":"Chenglong","family":"Cao","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China; and"},{"name":"Department of Cognitive Neuroscience, Maastricht University, Maastricht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingwu","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaofeng","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, The First Affiliated Hospital of USTC, Division of Life Sciences and Medicine, University of Science and Technology of China, Hefei, China; and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"9","key":"b1","series-title":"Curr Treat Options Neurol","first-page":"42","article-title":"Update on trigeminal neuralgia","volume":"21","author":"Tai AX","year":"2019","unstructured":"Tai AX, Nayar VV.
