Q

List all the things you could talk about for descriptive terminology

A
  1. skeletal location
  2. Position wihin the bone (metaphyseal, metadiaphyseal etc)
  3. Shape (round, oval, scalloped, pedunculated, sessile)
  4. Site of Origin (medullary, cortical, periosteal, extraosseus, or a combination)
  5. Size-
  6. Margination- useful for medullary pathologies (aggressuve, well defined-benign_
  7. Cortical Integrity
    - thinning, thickening, expansion, destruction, interuption.
  8. No. of lesions

Q

What are the patterns of bony destruction

A
  1. Osteolytic/ lucent lesios = BLACKER
    - both indicate a decrease in bone density
    - changes due to pressure erosions or osteoclastic activity.
  2. Sclerotic
  3. Geographic:
    - lucent destruction of bone, ususally from a nn-aggressive lesion.
    - lesions are usually over 1cm in diameter, and have sharp boarders
    - may be expansile or non expansile
  4. Moth-eaten:
    - invariably due to an aggressive lesion
    - focal, irregular and ill-defined areas of lytic bone destruction
    - lytic foci are or varying size
  5. Permiative-
    - invariably due to an aggressive lesion, ususally a tumor
    - focal pi’
  6. Osteoblastic/ sclerotic lesions:
    - increase in bone density
    - usaually reserved for an eggressive lesion, but not a specific rule
    - due to bone reaction to tumor.

Matrix (Depends on Tissue Origin) TISSUE TYPE

A

Fat
cartilage:
-typically lucent/ lytic- darker
-different types of calcification seen:
-Strippled (focal, relativekt uniform, small
-flocculent (larger, variable size and density, confluence od strippled Ca++
-Arc and Ring -thin curvlinear calcifications, typically seen in AGGRESSIVE lesions
-calcification usuallty cartilage matrix

Osseous-
classicly densly radio-opaque
