RT Journal Article SR Electronic T1 Technetium-99m DTPA Uptake in an Extra-Skeletal Myxoid Chondrosarcoma: Case Report JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol. FD Society of Nuclear Medicine SP 161 OP 163 VO 19 IS 3 A1 Fortenbery, Edwin J. A1 Norby, Eric H. YR 1991 UL http://tech.snmjournals.org/content/19/3/161.abstract AB Extra-skeletal myxoid chondrosarcoma (ESMC) is quite rare and was first described by Stout in 1953 (1,2). We describe a case of ESMC in which an abnormal accumulation of technetium-99m (99mTc) DTPA was detected in the area of the ESMC prior to eventual diagnosis. Recognition of 99mTc-DTPA uptake in ESMC may be of value in early diagnosis, and 99mTc-DTPA activity outside the urogenital tract can be an early sign of a hypervascular tumor and should not be dismissed.
