Candida esophagitis incidentally detected by 18F‐FDG PET/CT in a patient with CNS lymphoma

Corticosteroids are commonly used in lymphoma patients, and findings in favor of esophageal involvement in 18F‐FDG PET‐CT should be considered suspicious and definitely be confirmed by biopsy. We describe a 58‐year‐old lady with diffuse large B‐cell lymphoma and central nervous system involvement having an increased metabolism in the distal esophagus with 18F‐FDG PET/CT, which was consistent with esophageal candidiasis, most probably due to prolonged use of dexamethasone. Esophageal candidiasis can be misdiagnosed as malignancy with a high SUVmax and may lead to difficulties while managing these patients.
