Flare response in Ewing's sarcoma. 1991

J R Meyer, and B L Shulkin

Department of Radiology, University of Michigan Medical Center, Ann Arbor.

A 3 1/2-year-old boy had thigh pain and a leg mass. Bone scanning demonstrated intense uptake within the involved femur, but no uptake within the soft tissues or evidence of metastatic spread. Radiographs and CT scanning showed a large soft tissue mass and periosteal reaction suggestive of Ewing's sarcoma. Following chemotherapy, the patient had an apparently good clinical response. However, bone scanning showed uptake that was more intense and extensive than it was before therapy. Plain films and CT showed that the uptake was evidence of soft tissue calcification and that the mass had shrunk. This is an unusual example of the flare response to therapy because the apparent progression of the disease on bone scanning was caused by extraskeletal uptake.

D011877	Radionuclide Imaging	The production of an image obtained by cameras that detect the radioactive emissions of an injected radionuclide as it has distributed differentially throughout tissues in the body. The image obtained from a moving detector is called a scan, while the image obtained from a stationary camera device is called a scintiphotograph.

D012512	Sarcoma, Ewing	A malignant tumor of the bone which always arises in the medullary tissue, occurring more often in cylindrical bones. The tumor occurs usually before the age of 20, about twice as frequently in males as in females.
