Soft Tissue Inflammatory

• Multiple modalities– X-ray– Ultrasound– CT– MRI– Nuclear Medicine

Page 3: Soft Tissue Inflammatory Disease

Soft Tissue Inflammatory

• Multiple modalities– X-ray

• Evaluate for mass• Evaluate for soft tissue air• Evaluate for bone involvement

Page 4: Soft Tissue Inflammatory Disease

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

Page 5: Soft Tissue Inflammatory Disease

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

Page 6: Soft Tissue Inflammatory Disease

Thumb Abscess

• Soft tissue swelling• Central air collection

Page 7: Soft Tissue Inflammatory Disease

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

Page 8: Soft Tissue Inflammatory Disease

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

Page 9: Soft Tissue Inflammatory Disease

Peri-anal Abscess

• MRI fluid sensitive sequence

• Peri-anal abscess• Fistula tract

Page 10: Soft Tissue Inflammatory Disease

Brain Inflammatory Disease

• Encephalitis• Brain abscess

Page 11: Soft Tissue Inflammatory Disease

HIV Encephalitis

• High signal areas involving white matter• Multiple bilateral areas of involvement

Page 12: Soft Tissue Inflammatory Disease

Brain Abscess• Ring enhancement due to breakdown of

blood brain barrier• Ring enhancement may be thinner on side

towards ventricles
