Although it is very important to discriminate ameloblastoma from ameloblastic carcinoma in order to decide the appropriate operative procedure, this is difficult using conventional CT and MRI.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Case descriptions<\/jats:title>\n            <jats:p>We report a case of maxillar ameloblastoma in a 78-year-old man where FDG-PET\/CT was useful for making this discrimination. CT demonstrated a 31\u2009\u00d7\u200943\u2009\u00d7\u200946-mm mass in the left posterior maxillary sinus with destruction of its posterior and lateral wall and alveolar bone. MRI demonstrated a hypo- to isointense heterogeneous pattern on T1WI, heterogeneous hyperintensity with a prominent high-signal spot on T2WI, high signal intensity on DWI reflecting restricted diffusion, and strong heterogeneous enhancement. Because FDG-PET\/CT showed mild FDG uptake (SUVmax 2.40) by the mass, ameloblastoma, rather than ameloblastic carcinoma, was considered to be the correct diagnosis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Discussion and evaluation<\/jats:title>\n            <jats:p>It appears that ameloblastic carcinoma shows intense FDG uptake, whereas ameloblastoma shows mild or moderate FDG uptake, and only rarely intense FDG uptake. Our experience suggests that FDG-PET\/CT may be effective for discriminating ameloblastoma from ameloblastic carcinoma. Especially, in cases showing mild FDG uptake, benign ameloblastoma would seem the most likely diagnosis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>FDG-PET\/CT may be useful as an adjunctive modality for diagnosis, treatment planning and surveillance of ameloblastoma and ameloblastic carcinoma.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/s40064-015-0998-3","type":"journal-article","created":{"date-parts":[[2015,6,10]],"date-time":"2015-06-10T11:03:00Z","timestamp":1433934180000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["FDG-PET findings of Ameloblastoma: a case report"],"prefix":"10.1186","volume":"4","author":[{"given":"Satoshi","family":"Seno","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuhiro","family":"Kitajima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Go","family":"Inokuchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ken-ichi","family":"Nibu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoo","family":"Itoh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuo","family":"Ejima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryohei","family":"Sasaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koji","family":"Sugimoto","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuro","family":"Sugimura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2015,6,11]]},"reference":[{"key":"998_CR1","doi-asserted-by":"publisher","first-page":"449","DOI":"10.1259\/dmfr\/29356719","volume":"39","author":"B Devenney-Cakir","year":"2010","unstructured":"Devenney-Cakir B, Dunfee B, Subramaniam R, Sundararajan D, Mehra P, Spiegel J, Sakai O (2010) Ameloblastic carcinoma of the mandible with metastasis to the skull and lung: advanced imaging appearance including computed tomography, magnetic resonance imaging and positron emission tomography computed tomography.
