Internal herniation may be seen more frequently in patients with intra-abdominal surgery and malignancy history. We presented a 58-year-old male patient diagnosed with rectal adenocarcinoma seven years ago with a history of surgery and pelvic radiotherapy. When the abdominal computed tomography (CT) image was taken during routine oncology follow-up, a lesion mimicking a serosal implant on the anterior abdominal wall was detected. 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT imaging was performed the suspicion of recurrence. It was concluded that the lesion, which was evaluated as an implant in abdominal CT with 18F-FDG PET/CT imaging, was a spontaneously reducing internal herniation. 18F-FDG PET/CT imaging in cancer patients is crucial in illuminating the suspicion of recurrent lesions in these patients and sheds light on the course of the patients in oncology practice.
İnternal herniasyon karın içi cerrahi ve malignite öyküsü olan hastalarda daha sık görülür. Biz bu olgu sunumunda, 7 yıl önce rektal adenokarsinom tanısı almış, cerrahi ve pelvik radyoterapi öyküsü olan 58 yaşında erkek hastayı sunduk. Hastada rutin takiplerde çekilen abdomen bilgisayarlı tomografide (BT) karın ön duvarında serozal implant şüphesi olan lezyon saptandı. Nüks şüphesiyle çekilen 18F-florodeoksiglukoz (FDG) pozitron emisyon tomografi (PET)/BT ile BT’de implant olarak değerlendirilen lezyonun, spontan redüksiyon yapan internal herniasyon olduğu sonucuna varıldı. Kanser hastalarında 18F-FDG PET/BT görüntüleme bu hastalarda nüks şüphesinin aydınlatılmasında önemlidir ve onkoloji pratiğinde hastaların seyrine ışık tutar.
