Iron dextran: bone imaging patterns of absorption--a case report.

Abstract

This case illustrates two different patterns of absorption of Iron Dextran in the gluteal soft tissues due to an intramuscular and a more proper Z-track technique. A 65 year old female presented to the nuclear medicine service for a bone scan to rule out metastatic disease from a surgically resected colon cancer. While the first bone scan showed no evidence of metastases, an abnormal accumulation of Technetium-99m methylene diphosphonate was noted in the left gluteal soft tissue region.
