Aneurysmal bone cyst abc
Aneurysmal Bone Cyst (ABC)


Aneurysmal bone cyst abc1
Aneurysmal Bone Cyst (ABC)


Respect epiphyseal plate

soap-bubble

Thin internal trabeculations

Almost invesible cortex

Expansile lesion

No periosteal reaction except in case of fracture



Aneurysmal Bone cyst :

  • Occur secondary to fibrous dysplasia

  • Can present with scoliosis

  • May contain fluid-fluid level at MRI

  • Contain calcified matrix

  • Doughnut sign at scintigraphy is pathognomonic

Mulyiple osteolytic Punched-out lesion

Absence of perilesional sclerosis


Complicated by pathological fracture

Associated with osteopenia



Regarding Multiple Myeloma :

  • It is the commonest 1ry neoplasm of bone

  • Generalised osteopenia is a recognised appearance

  • Scintigraphy over-estimates disaese extent

  • Lesions becomes scleotic following chemotherapy

  • Vertebral pedicle destruction is an early event

(√ )

(√ ) in 15 %

(X ) under estimates

(√ ) also following radiotherapy

Joint deformity

Periarticular osteopenia

Narrowing of the joint spaces

Soft tissue swelling

Joint instability due to ligament rupture

Articular erosion


High ridding of the humerus

Lateral erosion of the clavicle

Marginal erosion

Narrowing of the glenohumoral joint



ligamentous destruction can result in atlantoaxial impaction

Erosion of Odontoid process

Pannus proliferation directly compresses the spinal cord.

Erosion of facet joints


Erosion of the lateral 3rd of the clavicle is seen in the following:

  • Rheumatoid arthritis

  • Ankylosingspondylitis

  • Langerhans cell histiocytosis

  • Hypoparathyroidism

  • Multiple myeloma

Concerning Malignant bone lesion:

  • Chordoma is most common in the thoracolumbar spine

  • Fibrosarcoma is the commonest tumour 2ry to paget’s disease

  • Adamantinomaoccursin the tibia in over 90% of cases

  • Angiosarcoma has a soap bubble appearance at radiography

  • Chondroblastoma are typically found in the diaphysis

(X ) 90% in basisphenoid and sacrum
