1. Dr/ ABD ALLAH NAZEER. MD.
X-Ray Film Reading of bone tumors.

3. Radiographic appearance of osteochondroma. Lesions are most common
in the metaphysis of long bones and may be pedunculated (A) or flat (B).

5. Hereditary multiple exostosis (HME).

7. Two cases with osteochondroma and
malignant transformation

9. Enchondroma.

11. Enchondroma. Enchondroma with fracture.

13. A) Enchondroma of the proximal phalanx of the little finger; (B) Enchondroma
at the lower metaphysis of the femur with cartilage calcification- rings and
arcs; (C) low grade chondrosarcoma in mid shaft of femur

15. Multiple enchondromas.

17. a X-ray of right proximal humeral cyst in a nine-year-old boy presenting with pathological
fracture. b After two ABMI the cyst showed signs of healing. c Reactivation and enlargement
of the cyst with pathological fracture. d After healing of the fracture the cyst became latent.

19. (Left) Typical UBC is shown in the humerus, the most common location for this lesion. It is several
millimeters from the open growth plate . The metaphysis appears slightly widened , but its diameter
does not exceed the width of the growth plate. (Right) Typical UBC is shown in the proximal femur, the
2nd most common location. The lesion extends to the open growth plate and, although it has thinned
the cortex , the profile of the bone is not significantly widened.

21. Radiograph demonstrates an aneurysmal bone cyst in the hand.

23. Aneurysmal bone cyst (ABC) - tibia

25. OSTEOID OSTEOMA.

27. Multicentric Osteoid Osteoma .

29. Imaging characteristics of spinal osteoid Osteoma (OO) and osteoblastoma (OB). Typical
examples of a spinal OO (left and middle column) and a spinal OB (right column).

31. Osteoblastoma of left L3 and
L4 transverse process.

33. Giant cell tumor.

35. Giant cell tumor.

37. Core Biopsy taken for Histopathology had features suggestive of giant cell tumor.

39. Benign epiphyseal chondroblastoma A) x-ray & CT picture of tibia with a
lytic lesion restricted to the epiphysis; (B) X ray of a large
chondroblastoma of femoral head (right), transgressing part of epiphyseal
plate and causing destruction of sub epiphyseal bone and trochanter.

41. Chondrobalstoma.

43. Fibrous dysplasia.

45. Fibrous dysplasia involvement of the right femur.

47. Fibrous dysplasia.

49. Cortical fibrous defects.

51. Fibrous Cortical Defect.

53. Non-ossifying fibroma.

55. Non-ossifying fibroma.

57. Chondromyxoid fibroma:

59. Ewing Sarcoma.

61. Ewing Sarcoma.

63. Ewing Sarcoma.

65. Plain films show an
expansile lesion. The MR
shows cortical destruction
and soft tissue extension.
Diagnosis: Chondrosarcoma,
proximal radius

67. Chondrosarcoma of the proximal phalanx of the ring finger

69. Peripheral chondrosarcoma in the femur.

71. Parosteal osteosarcoma.

73. Osteosarcoma with Codman’s triangle.

75. Osteosarcoma

78. Lymphoma. (A) Anteroposterior and oblique radiographs of the right humerus of a 20-year-old man
show a long lesion exhibiting permeative and moth-eaten type of bone destruction. Periosteal reaction
is secondary to the pathologic fracture. (B) Sagittal reformatted CT image demonstrates endosteal
scalloping and early callus formation at the site of a pathologic fracture (arrows).
