Its clinical presentation typically consists of progressive focal muscle atrophy and weakness. In addition to motor disorders, the association between ALS and cancer has been researched, such as frontotemporal dementia and progressive supranuclear palsy. The diagnosis is based primarily on the clinical history, physical examination, electrodiagnostic tests (with an EMG needle), and neuroimaging, such as MRI and <jats:sup>18<\/jats:sup>F-FDG PET\/CT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Presentation of the case<\/jats:title><jats:p>A 67-year-old male patient was diagnosed with prostate adenocarcinoma with a clinical picture of muscle weakness in the lower limbs that caused falls and was associated with fasciculations in the thighs and arms, alterations in the tone of voice, poor memory, and difficulty articulating words. In the neurological assessment, he described walking supported by a walker with decreased strength in both lower limbs and sensitivity without alterations. The diagnoses of upper and lower motor neuron disease and probable ALS were integrated. Furthermore, the probable coexistence of frontotemporal dementia\/disorder (FDD) with ALS was considered. The main findings in the <jats:sup>18<\/jats:sup>F-FDG PET\/CT study was hypometabolism in the cortex of the bilateral motor and premotor areas, the anterior cingulate, both caudate and putamen, a metabolic pattern compatible with ALS, and progressive supranuclear palsy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Through the PET\/CT studies, we demonstrated a case in which ALS, prostate cancer and progressive supranuclear palsy coexisted molecularly; it was clinically difficult to diagnose. Molecular imaging has potential in the diagnostic and prognostic evaluation of ALS. It is crucial to identify the disease early and reliably through metabolic patterns that allow us to confirm the disease or differentiate it from other pathologies.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnume.2023.1137875","type":"journal-article","created":{"date-parts":[[2023,4,17]],"date-time":"2023-04-17T05:53:31Z","timestamp":1681710811000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["18F-FDG PET\/CT as a molecular biomarker in the diagnosis of amyotrophic lateral sclerosis associated with prostate cancer and progressive supranuclear palsy: A case report"],"prefix":"10.3389","volume":"3","author":[{"given":"Emilly A.","family":"Cort\u00e9s Mancera","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio A.","family":"Sinisterra Solis","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco R.","family":"Romero-Castellanos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivan E.","family":"Diaz-Meneses","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nora E.","family":"Kerik-Rotenberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,4,17]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1918","DOI":"10.1111\/ene.14393","article-title":"Amyotrophic lateral sclerosis: a clinical review","volume":"27","author":"Masrori","year":"2020","journal-title":"Eur J Neurol"},{"key":"B2","doi-asserted-by":"publisher","first-page":"942","DOI":"10.1016\/S0140-6736(10)61156-7","article-title":"Amyotrophic lateral sclerosis","volume":"377","author":"Kiernan","year":"2011","journal-title":"Lancet"},{"key":"B3","doi-asserted-by":"publisher","first-page":"647","DOI":"10.1212\/01.wnl.0000200962.94777.71","article-title":"The natural history of primary lateral sclerosis","volume":"66","author":"Gordon","year":"2006","journal-title":"Neurology"},{"key":"B4","doi-asserted-by":"publisher","first-page":"310","DOI":"10.3109\/17482960802566824","article-title":"Prognostic factors in ALS: a critical review","volume":"10","author":"Chio","year":"2009","journal-title":"Amyotroph Lateral Scler"},{"key":"B5","doi-asserted-by":"publisher","first-page":"994","DOI":"10.1016\/S1474-4422(07)70265-X","article-title":"Deterioro cognitivo en la esclerosis lateral amiotr\u00f3fica","volume":"6","author":"Phukan","year":"2007","journal-title":"Lancet Neurol"},{"key":"B6","first-page":"390","article-title":"Case presenting both clinical features of progressive supranuclear palsy and amyotrophic lateral sclerosis","volume":"46","author":"Inoue","year":"2006","journal-title":"Rinsho Shinkeigaku"},{"key":"B7","doi-asserted-by":"publisher","first-page":"168","DOI":"10.1186\/s12883-019-1402-7","article-title":"Co-morbidity of progressive supranuclear palsy and amyotrophic lateral sclerosis: a clinical-pathological case report","volume":"19","author":"Fujita","year":"2019","journal-title":"BMC Neurol"},{"key":"B8","first-page":"1173","article-title":"A case of amyotrophic lateral sclerosis associated with clinical features of progressive supranuclear palsy","volume":"29","author":"Wakamatsu","year":"1989","journal-title":"Rinsho Shinkeigaku"},{"key":"B9","doi-asserted-by":"publisher","first-page":"e1001257","DOI":"10.1371\/journal.pgen.1001257","article-title":"Cancer and neurodegeneration: between the devil and the deep blue sea","volume":"6","author":"Plun-Favreau","year":"2010","journal-title":"PLoS Genet"},{"key":"B10","doi-asserted-by":"publisher","first-page":"55","DOI":"10.1007\/s10552-012-0089-5","article-title":"The association between cancer and amyotrophic lateral sclerosis","volume":"24","author":"Freedman","year":"2013","journal-title":"Cancer Causes Control"},{"key":"B11","doi-asserted-by":"publisher","first-page":"293","DOI":"10.1080\/146608200300079536","article-title":"World federation of neurology research group on motor neuron diseases.
