title: Transient Osteoporosis of the Hip on FDG PET/CT.
abstract: Transient osteoporosis of the hip (TOH) is characterized by bone pain, osteopenia, and bone marrow edema in the absence of trauma. We present a 59-year-old man with chronic lymphocytic leukemia who underwent F-FDG PET/CT. F-FDG PET/CT demonstrated mildly FDG-avid lymph nodes consistent for chronic lymphocytic leukemia, as well as FDG-avidity in the right femoral head with corresponding osteopenia, rather than a focal lytic lesion. MR demonstrated bone marrow edema consistent with TOH. TOH is benign and self-limiting. Corresponding imaging may prevent misdiagnosis of benign FDG-avid TOH as other more severe hip processes such as tumors or infection.
