30 year old male presents to the clinic with pain in his left ankle. Radiographs shown exhibit a soap
bubble appearance lesion, with extensive destruction of medullary and cortical bone. What is the likely
diagnoses? - correct answer ✔✔giant cell tumor
What is a tumor that is typically seen in the third or fourth decades of life. It presents largely in the
epiphysis, but can cross over to the metaphysis and diaphysis, eventually damaging the subchondral
plate. It can also undergo malignant transformation and may be associated with hyperparathyroidism? -
correct answer ✔✔Giant cell tumor
A 36-year-old female presents with lytic distal tibial lesion and a lung nodule on chest x-ray. Which of the
following is highest on her differential diagnosis? - correct answer ✔✔giant cell tumor
A 9 year old patient presents with an angular deformity of his tibia. X-rays show a hazy, ground-glass
appearance at the site of angulation. What is the most likely diagnoses here? - correct answer
✔✔Fibrous dysplasia
, A patient presents with hyper melanin pigmentation. Doctors suspect a disorder that affects her
endocrine system. What bone lesions could you possibly suspect this patient develops? - correct answer
✔✔Fibrous dysplasia
What bone tumor is tpically a multiloculated lucent lesion with a sclerotic rim. They are located
eccentrically in the metaphysis, adjacent to the physis. As the patient ages, they seem to migrate away
from the physis. They have no associated periosteal reaction, cortical breach or associated soft tissue
mass? - correct answer ✔✔Nonossifying fibroma
Radiographs of which bone tumor demonstrate well defined, lucent, central medullary lesions that
calcify over time , 1 to 10cm in size metaphyseal location when they first appear, appear more diaphyseal
as the long bone grows, "pop-corn" stippling, arcs, whorls, rings? - correct answer ✔✔Enchondroma

include a lesion comprising of both cortical and medullary bone with an overlying cap of hyaline
cartilage. In very rare instances, they can transform into malignant chondrosarcoma. - correct answer
✔✔Osteocondromas
What is the name of the tumor that is a benign tumor, and usually occurs in the epiphysis; usually is seen
when the growth plate is open. The tumor is usually painful and on imaging will classically demonstrate
surrounding edema and enhancement on MRI? - correct answer ✔✔Chondroblastoma
