Editor's Notes

  1. Maffucci syndrome CARTILLAGE FORMING
  2. Source WHIO manual
  3. Enchondroma , Maffucii sybdrome and olliers disease will be discussed together.
  4. pathognomonic
  5. INVOLVEMENT OF SOFT TISSUE IS ALMOST EXCLUSIVELY SEEN IN MAFUCCIS
  6. Despite being rare, they are one of the most frequently encoutered benign epiphyseal neoplasms in skeletally immature patients. *which may lead to the incorrect diagnosis of giant cell tumour) which may lead to the incorrect diagnosis of giant cell tumour)
  7. cT demonstrates the plain film findings with better delineation of the relationship to the growth plate and articular surface
  8. CHONDROBLASTOMA OF SCAPULA TIBIA epiphyseal  well defined lytic lesions; either smooth or lobulated margins with a thin sclerotic rim Internal calcifications can be seen .
  9. Fluid-fluid levels may occasionally be seen (see fluid fluid level containing bone lesions) presumably due to an associated aneurysmal bone cyst
  10. T1 - lesion itself is of low to intermediate signal T2 / STIR - lesion is of intermediate to high signa
  11. T1 and t2 images see the cartilage differences .
  12. Examples have however been seen in patients up to the age of 75 years. In some series there is a male predilection 12 whilst in others no such distribution is found
  13. STIR T2 FAST SAT T1 t1 FAST c++
  14. T1 C+FAST
  15. Tests like FNAC is usually non-diagnostic and is dominated by fresh blood 
  16. . Occasionally they are also seen in appendicular long bones where they are known as solid aneurysmal bone cysts. Histologically these two entities are identical 6.
  17. fluid-fluid levels,  no means unique to it, and is also seen in both benign and malignant lesions (e.g. giant cell tumours (GCT), chondroblastoma, simple bone cysts and telangiectatic osteosarcomas).
  18. Also seen in giant cell tumour simple bone cyst On plain films (and to a lesser degree CT) the diagnosis includes most of the lesions
  19. Allows detailed in view of the lesion can be of two types in general
  20. T1 slices
  21. the rightmandible with expansion of buccal and lingual cortical plates. Ameloblastoma
  22. Explain the graphs
  23. In some locations, such as in the humerus or around the knee, almost all bone tumors may be found.
  24. Simple bone cyst
  25. Anteroposterior radiograph of the pelvis shows expansile lytic lesion of right acetabulum with thinning of the cortex (arrow) and honeycomb trabeculation. Flat bones are a common location for aneurysmal bone cysts
  26. Anteroposterior radiograph of proximal portion of tibia and fibula shows expansile lytic lesion in proximal fibular metaphysis, with mild honeycombing (black arrows). Eccentric origin of the lesion is hard to appreciate in thin bones such as the fibula; both cortices are ballooned, with focal loss laterally (white arrow).
  27. Anteroposterior radiograph of distal forearm and wrist shows more typical eccentric location of aneurysmal bone cyst in distal metaphysis of the radius, although this particular lesion lacks a honeycomb appearance. Cortex on radial side is very thin
  28. Lateral radiograph of proximal portion of tibia shows enchondroma with punctate and arclike mineralization (arrows).
  29. Lateral margin of 10t rib Enchoi-0
