Bone Tumours Flashcards
A bony outgrowth from the cortex with a cartilaginous cap is seen on radiograph.
What is the likely lesion?
Osteochondroma
A lucent intramedullary lesion with patchy sclerotic areas is seen on radiograph.
What is the likely lesion?
Enchondroma
Osteochondroma is typically seen in what patient group?
Is it benign or malignant?
Males < 20 y/o
Benign
What is the most common primary bone tumour?
Osteochondroma
How old are patients who typically develop giant cell tumours?
20 - 40 y/o
Where do giant cell tumours normally develop?
The epiphysis of long bones
Are giant cell tumours being or malignant?
benign - although 5% may metastasise to lung
X-ray shows a “double-bubble” or “soap-bubble” appearance.
What is the likely lesion?
Giant cell tumour
What is the management of giant cell tumours?
Intralesional excision
Bone angulation occurs in a adolescent, leading to “Shepard’s crook” deformity.
What is the likely lesion?
Fibrous dysplasia of bone
What is the management of fibrous dysplasia?
Bisphosphonates for pain
Manage pathological fractures as they arise
This lesion affects 10-25 y/o males. They often suffer constant pain that is worse at night.
X-ray shows a central radiolucent nucleus and sclerotic halo.
What is the likely lesion?
Ostoid osteoma
What is the management for osteoid osteoma?
NSAIDs for pain
Spontaneous resolution may occur
If not; CT guided radio-frequency ablation
45-64 y/o with multiple “punched-out” osteolytic lesions.
What is the likely diagnosis?
