Summary

This study presents a rare case of adult reflex sympathetic dystrophy (RSD) showing decreased bone scan uptake, contrasting with typical increased uptake. The review covers RSD in both adults and children.

Area of Science:

  • Nuclear medicine
  • Radiology
  • Skeletal imaging

Background:

  • Reflex sympathetic dystrophy (RSD), also known as complex regional pain syndrome, is a poorly understood condition.
  • Classical triple-phase bone scintigraphy in RSD typically shows increased periarticular uptake in all phases.

Observation:

  • This report details a rare case of acute adult RSD.
  • The patient presented with an unusual pattern of hypofixation (decreased uptake) of Tc-99m MDP on bone scintigraphy.

Findings:

  • The observed hypofixation is atypical for the classical presentation of RSD.
  • This case challenges the conventional scintigraphic findings associated with RSD.

Implications:

  • The findings suggest that RSD diagnosis requires considering atypical presentations.

Related Experiment Videos

  • Further research is needed to understand the mechanisms behind hypofixation in RSD.
  • This case highlights the importance of integrating imaging findings with clinical presentation.
