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)
Phleboliths
Inside veins
Oval shaped, or
shape of rice kernel
Calcifications
Osteopathia striata
Asymptomatic
Linear, regular bands
of increased density
parallel to shaft, from
metaphysis to
diaphysis
