The rapidly evolving clinical utility of prostate-specific membrane antigen (PSMA) PET/CT as an imaging modality for prostate cancer (PCa) has brought to the forefront a multitude of non-prostatic diseases also exhibiting PSMA radioligand uptake. We report a case of a 71-year-old male with PCa who underwent PSMA PET/CT for recurrence evaluation. The scan demonstrated [68 Ga]Ga-PSMA-11 uptake in the distal ileum. Retrospective enquiry revealed that the patient was a known case of Crohn's disease. This case highlights an uncommon finding of PSMA radioligand uptake in the distal small bowel (non-prostatic benign pathological uptake) in a patient with known Crohn's disease, which may be misinterpreted in the evaluation of PCa.
前列腺特异性膜抗原(PSMA)PET/CT作为前列腺癌(PCa)成像方式的临床应用迅速发展,这使得众多非前列腺疾病也表现出PSMA放射性配体摄取这一情况被推到了前沿。我们报告一例71岁的PCa男性患者,其接受PSMA PET/CT以评估复发情况。扫描显示[68Ga]Ga-PSMA-11在回肠末端摄取。回顾性询问发现该患者是已知的克罗恩病病例。该病例突出了在一名已知克罗恩病患者的远端小肠中出现PSMA放射性配体摄取(非前列腺良性病理摄取)这一罕见发现,这在PCa评估中可能会被误解。
