Epithelioid osteoblastoma is a clinically aggressive subtype of osteoblastoma that favors the mandible and the maxilla. Its histologic features lie on a spectrum between conventional osteoblastoma and low-grade osteosarcoma, thus making it difficult at times to confirm the diagnosis. It is known to have a high risk of recurrence after surgical resection, but it is a benign entity and does not have the propensity to metastasize. To our knowledge, there are no published reports on findings of epithelioid osteoblastoma on positron emission tomography/computed tomography (PET/CT). We report a case of a 25-year-old male patient with a diagnosis of epithelioid osteoblastoma of the mandible. The lesion exhibited significantly increased fluorodeoxyglucose uptake on PET/CT with a maximum standardized uptake value of 5.5. PET/CT is not specific in differentiating between malignant and benign bone lesions but may be necessary to rule out distant lesions when a confirmed diagnosis of epithelioid osteoblastoma cannot be obtained through histologic examination.
