endocrine Flashcards
scurvy
Wimberger’s sign (ring)- epiphysis has an outer shell of increased density surrounding central lucency
Hemorrhaging
Widening of metaphysis
Scurvy lines- transverse lines of increased density
Rickets
Osteopenia
Bowing of the long bones
Looser’s zones (lines)- transversely oriented incomplete radiolucency’s, known as pseudo-fractures
paint brush appearance
Acromegaly
Increase in fat pad
thickness (>23mm)
Prominent bones
Increase joint space
(cartilage)
Lead Poisoning
Thick sclerotic
transverse banding
at metaphysis
Multiple bands
Paget’s Disease
Classic triad- cortical
thickening,
prominent trabecular
pattern, and increase
in bone size.
Hyperparathyroidism
Subperiosteal bone
resorption
Brown tumors -
hemosiderin rich
Pseudohypoparathyroidism
Associated with short
metatarsals
Osteogenesis Imperfecta
Osteopenia
Decreased bone
girth
2nd fractures result
Osteopetrosis
Inherited
diffuse bone sclerosis
Its characteristic
feature has been
described as a “bone
within a bone”
Melorheostosis
Endosteal cortical
thickening
Hyperostosis along
the bone’s periphery,
extending along its
entire length
Wax flowing down a
candle
Osteopoikilosis
Multiple geographic
increased densities
(bone islands) in
periarticular areas.
Thalassemia
Bone marrow
hyperplasia
Cortical thinning
Reticulated trabecular
pattern
Radiolucency of bone
CRPS/RSD
Dysfunction of nervous system resulting in
vasomotor changes
Stage 2: Sudek’s
atrophy- is spotty
osteopenia
Moenckeberg’s sclerosis
Tubular serpiginous
calcification
Calcification of media
layer of arteriole
(muscle layer)
Seen a lot in diabetics
Atherosclerosis
Plaque in the lumen
can decrease blood
flow
Thinner, curvilinear
(not tubular)
