18F-FDG PET/CT in Graft Versus Host Disease–Associated Polymyositis

We present a case of a 38-year-old man with a known case of mixed-phenotype acute leukemia after hematopoietic stem cell transplant presenting with GVHD-associated polymyositis. 18F-FDG PET/CT done in this case not only helped in the detection of the muscle involvement but also helped in obtaining precise muscle sample for histopathological diagnosis using PET-guided biopsy.
