Imaging and Treatment of Post–90Y Radioembolization Radiation Dermatitis

90Y microspheres have been widely used for treatment of liver-dominant malignancies. There have been a few case reports of radiation dermatitis post–inadvertent falciform artery 90Y radioembolization and a few retrospective studies with prophylactic coiling or use of ice packs prior to radioembolization. Our patient had inadvertent falciform artery radioembolization, which was not predicted on pretherapy angiography or 99mTc–macroaggregated albumin SPECT/CT but was localized on posttherapy 90Y PET/CT and treated with topical betamethasone valerate 0.1% BD and ice packing immediately postprocedure. He subsequently developed a small area of periumbilical radiation dermatitis, which resolved after 4 weeks. Received for publication August 28, 2018; revision accepted October 31, 2018.
