De la Cerda-Vargas","José Antonio Candelas Rangel","Elizabeth Meza Mata","Araceli Ramírez-Cárdenas","Bayron A. Sandoval-Bonilla"],"abstract":"Background: Actinomycosis is a rare infection, frequently misdiagnosed as a neoplasia. This chronic and granulomatous disease is caused by Actinomyces israelii species. Cervicofacial actinomycosis occurs in 60% of cases and the diagnosis is commonly made by histopathology study. Case Description: We report a case of fronto-orbital osteomyelitis initially misdiagnosed as a cranial bone meningioma, but later proved to be a case of actinomycosis. 99mTechnetium (99mTc) three-phase bone single-photon emission computed tomography/computed tomography (SPECT/CT) and 99mTc-ubiquicidin (UBI) 29-41 bone SPECT/CT scans were performed to corroborate the control of the infection. Conclusion: Craniofacial actinomycosis is the most common presentation of actinomycosis. However, it continues to be a rare and difficult disease to diagnose and is often confused with a neoplastic process. The 99mTc-UBI 29-41 bone SPECT/CT scan could be an auxiliary noninvasive diagnostic alternative and a follow-up method for these patients.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/7b4e4285-e2a5-4492-8ec2-588babed3ded/featured/hero-1781562885340.png","publishDate":"2020-12-16T00:00:00.000Z","doi":"10.25259/SNI_684_2020","categories":["Infection","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/7b4e4285-e2a5-4492-8ec2-588babed3ded/pdf"}
