Fig. 69.1 (a) Acute osteomyelitis. In the earliest phase, there is no change in the bone (left); the MRI panels demonstrating fluid in the marrow taken at the right demonstrate…

Most cases of CMF occur in the metaphysis of tubular bones of the lower extremity. Approximately one-third of the cases are diagnosed around the knee joint, especially the proximal tibial…

Metaphysis or diaphysis of long bones, especially around the knee. Femur, tibia, and humerus are, in this order, the more frequent locations. Pelvis, especially the ilium, follows in frequency. About…

Slightly greater incidence in males than females. Age The first two decades of life account for 80 % of patients (age at diagnosis ranges from 13 to 19 years), being…

Fig. 67.1 Gaucher disease involving the humerus. Note the radiolucency with cortical scalloping involving the distal diaphysis; the trabecular pattern of the distal end is spared Fig. 67.2 Gaucher disease…

Fig. 3.1 (a–d) Puncture needle biopsy in cervical spine in a patient with metastatic carcinoma. In cases like this, fine needle or core needle biopsy is undoubtedly a better alternative…

Fig. 38.1 Benign notochordal cell tumor involving the S3 of the sacrum in a 31-year-old man. Sagittal (a) and axial (b) computed tomographic scans show a slightly sclerotic mass in…

Any bone can be involved. Most cases occur in the jaw; metaphysis of long bones, especially the distal end of the radius; scapula; and pelvis. Clinical Symptoms and Signs Local…

Radiographically, angiosarcoma usually is a completely lytic, uni- or multilocular lesion, with medullar and cortical permeation. Less commonly, it may be sclerotic or mixed, lytic and sclerotic. It usually has…
