Presentation Transcript

  1. Soft Tissue Inflammatory Disease

  2. Soft Tissue Inflammatory • Multiple modalities • X-ray • Ultrasound • CT • MRI • Nuclear Medicine

  3. Soft Tissue Inflammatory • Multiple modalities • X-ray • Evaluate for mass • Evaluate for soft tissue air • Evaluate for bone involvement

  4. Soft Tissue Inflammatory • Multiple modalities • Ultrasound • Soft tissue changes • Fluid • Air with shadowing • CT • Soft tissue changes • Dirty fat (edema in fat) • Soft tissue air

  5. Soft Tissue Inflammatory • Multiple modalities • MRI • Likely best for imaging of soft tissue inflammatory changes • Evaluate for fluid collections • Evaluate for edema • Nuclear Medicine • Labeled white cells • Identify areas of active infection

  6. Thumb Abscess • Soft tissue swelling • Central air collection

  7. Soft Tissue Abscess • Abscess quite similar to adjacent soft tissues • Very hard to identify on standard radiographs • US, CT and MRI most effective imaging technique • Abscess lower signal on T1 images • High signal on proton density and T2 images

  8. Inflamed Lipoma • Rim like zone on T1 • Fluid signal on Stir • Ring enhancement on C+

  9. Peri-anal Abscess • MRI fluid sensitive sequence • Peri-anal abscess • Fistula tract

  10. Brain Inflammatory Disease • Encephalitis • Brain abscess

  11. HIV Encephalitis • High signal areas involving white matter • Multiple bilateral areas of involvement

  12. Brain Abscess • Ring enhancement due to breakdown of blood brain barrier • Ring enhancement may be thinner on side towards ventricles
