Transient Osteoporosis of the Hip on FDG PET/CT
1From the Department of Radiology, Memorial Sloan Kettering Cancer Center, New York; and Department of Radiology, Weill Cornell Medical College, New York, NY.
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.
