Q

True or false; all 3 fibrous pathologies we discussed in class begin and end in childhood (resolve on their own)

A

False; Fibrous dysplasia persists into adulthood

Non-ossifying fibroma is in between - if >8cm in size will need cutterage and bone chips to help resolve

Q

MC location of endochondroma

A

24
Q

MC location of hemangioma

A

vertebral body

25
Q

Second MC location for ABCs

A

Knee

26
Q

What should your differential diagnoses be if you see the MRI of a hemangioma?

A

Solitary plasmocytoma (look in your book - or google image them - they look very similar but plasmocytoma has a more “blown out” appearance)

27
Q

True or false: Aspirin will relieve the pain from an osteoblastoma

A

false; will relieve pain from osteiod osteoma

28
Q

MC location for osteoid osteoma

A

proximal femur - bird nidus appearance

29
Q

What pathology is associated with the “fallen fragment sign” and how likely are you to see it on an X-ray?

A

Solitary bone cyst

Very likely. SBC’s are typically asymptomatic until a fx occurs which causes the fallen fragment sign which is a piece of bone floating in the serous fluid

30
Q

MC benign tumor of bone

A

solitary osteochondroma

31
Q

True or false; solitary osteochondromas typically cause a host of symptoms including pain

A

False; typically are asymptomatic until a trauma to the area causes pain

32
Q

What is the common treatment for GCTs

A

Surgical curettage with liquid nitrogen freezing

33
Q

MC location of osteoblastoma

A

neural arch followed by long bones

34
Q

If a patient had a painful scoliosis what should be your first thought?

A

Osteoblastoma

35
Q

True or false; osteoblastomas are typically asymptomatic

A

false; 84% have a dull pain that is worse at night

36
Q

“rain drop skull” is associated with

A

Multiple myeloma

37
Q

True or false; Multiple myeloma commonly affects the skull

A

true “rain drop skull”

38
Q

Age of occurrence in chondrosarcoma

A

usually over 50 years

39
Q

True or false; Chondrosarcoma typically causes pain quickly after development

A

false; has late development of pain

40
Q

Age of occurrence for all fibrous diseases (fibrous cortical defect, non-ossifying fibroma, fibrous dysplasia)

A

2-10 years

41
Q

True or false; chondrosarcoma’s and enchondroma’s are easy to differeniate on plain film

A

false; need to tie in clinically - both have “popcorn calcification”

42
Q

What is onchondromatosis/Ollier’s disease?

A

Multiple enchondromas

causes deformity in hands and feet

43
Q

True or false; ABCs are typically slow growing

A

false; the most rapid growing tumor we talked about - causes extreme pain

44
Q

True or false; Multiple myeloma likes the diaphseal region

A

true

45
Q

Where does ewing’s sarcoma like to be in bone

A

diaphyseal region

46
Q

A double density sign on bone scan is associated with

A

osteoid osteoma

47
Q

Fluid fluid levels =

A

ABCs

48
Q

What is a rind sign? And what is it associated with?

A

Thick sclerotic ring - fibrous dysplasia

49
Q

What disease is osteoporosis circumscripta associated with

A

paget’s disease (stage 1 - lytic)

50
Q

Rim sign in the pelvis =

A

Paget’s disease (stage 2 - mixed)

51
Q

One eyed pedicle sign =

A

Could be congenital or lytic mets - need to tie in clinically or order MRI

52
Q

Blade of grass sign =

A

Paget’s disease in long bones

53
Q

Picture frame vertebrae =

A

paget’s disease in vertebrae

54
Q

Ivory vertebrae =

A

Metastatic bone dz
Paget’s
Lymphoma

55
Q

Only 2 pathologies women are more likely to get

A

ABCs and Hemangiomas
