Bone 2 : 🔴 Sclerotic In men: ca prostate 🔴 sclerotic in women: ca breast. 🔴 Metastases with bone expansion occur in primary tumours of the kidney and thyroid. 🔴 A periosteal reaction with metastases, uncommon except in neuroblastoma. 🔴 A radionuclide bone scan is much more sensitive for detecting metastases than plain films 🔴 Multiple myeloma : bone scan is not so sensitive for detection MRI is very sensitive in detection. 🔴 Lymphoma and leukaemia : bone destruction, mostly in the metaphyseal regions. Bone lesions are very rare in adult leukaemias. 🟣 osteoporosis : penciled in cortex wedged or biconcave vertebral body 🟣 Disuse Osteoporosis : bone may sometimes have a spotty appearance. 🟣 in OP : BMD is a poor predictor of an individual’s fracture risk 🟣 Osteomalacia : Biconcave vertebral bodies Bowed femora triradiate pelvis. Loozer’s Zones 🟠 Hyperparathyroidism : The hallmark :sub-periosteal bone resorption: hands on the radial side of the middle phalanges, tips of the terminal phalanges. Brown tumours: well defined lytic lesions, single or multiple. Salt and pepper appearance in the scalpe 🟡 Renal Osteodystrophy : rugger jersey spine 🟤 Myelosclerosis : patchy extratrabecular bone formation huge spleen 🔵 Paget disease: : In the skull : mottled appearance :cotton wool. An increased thickness of the calvarium is a particularly obvious feature. 🔴 Marrow hyperplasia : perpendicular striations giving an appearance known as ‘hair-on-end’ 🟡 Chondrosarcoma suspected if there is either : 1. rapid growth, 2. an ill-defined edge to the bone, 3. or extensive calcification extending into the soft tissues.

بعض الملاحظات المهمة Bone 1 : 🔴 Osteosarcoma : sunray appearance Codman’s triangle. X ray diagnostic 🔴 Fibrosarcoma an ill-defined area of lysis with periosteal reaction. 🔴 Ewing’s sarcoma : onion skin’ 🔴 Giant cell tumour : It occurs most commonly around the knee and at the wrist after the epiphyses have fused. 🔵 Enchondromas : -lytic expanding lesions most commonly in the bones of the hand -contain a few flecks of calcium -present as a pathological fracture. 🔵 simple bone cyst The cortex may be thin and the bone expanded. Often, the first clinical feature is a pathological fracture. 🔵 osteoid osteoma : -nidus, surrounded by dense sclerotic rim. -An important imaging investigation is radionuclide bone scanning, which shows marked focal increased activity. 🔵 Eosinophil granuloma : -produces lytic lesions which may be single or multiple, -Extensive lesions : called geographic skull 🟢 Chronic OM : Brodie’s abscess.
