Multiple Myeloma is a neoplasm of differentiated plasma cells resulting from malignant clonal expansion and overproduction of monoclonal immunoglobulins. Common complications include recurrent bacterial infections, anemia, osteolytic lesions and renal insufficiency.

Definition Neurofibromatosis type I (NF-1), along with Neurofibromatosis type II (a.k.a. MISME syndrome), Tuberous Sclerosis, Sturge-Weber, and Von Hippel-Lindau compromise the phakomatosis or neurocutaneous syndromes, all of which have neurologic and dermatologic lesions. This grouping is an artifact of an earlier time in medicine, before the distinct genetic basis of each of these diseases was understood. Etiology Neurofibromatosis type I (NF-1), also known as von Recklinghausen disease, is the result of a defect on Chromosome 17. from Diagnostic Radiology/Musculoskeletal Imaging/Dysplasia Basic/Neurofibromatosis From Wikibooks, the open-content textbooks collection

To detect and appreciate injuries of the cervical spine, you must be aware of the normal radiographic appearances and anatomical features of this region. This section will review the typical x-ray examinations seen by an emergency physician. Usually FIVE different projections will be obtained with the initial film a cross table lateral view. This is a lateral (side on) view of the spine which can be taken without significant movement of the patient. This film should be reviewed by a physician before any other films of the cervical spine are obtained. A severe injury documented at this stage will mean fewer films before stabilization is made secure and those films requiring movement will be omitted. Remember that plain films will need to be supplemented by more detailed and precise tomographic examinations in many cases.

Bilateral, symmetric sclerosis of the iliac side of the sacro-iliac joint is present in this young female, who presents with an unrelated history (motor vehicle accident). The sclerosis appears triangular with the base located inferiorly. Erosions are absent. some facts concerning Osteitis Condensans Ilii: Symmetric sclerosis of the iliac side of the sacro-iliac joint found in young multiparous women. Can be seen in males. Felt to be a stress related phenomenon secondary to instability at the symphysis pubis. May be painful. May spontaneously resolve on cessation of stress or on surgical stabilization at the symphysis pubis.

Radiology case 451-442
Clinical presentation: 13 year old male with pain in the knees. There are almost symmetrical defects of the articular surfaces on the medial side of the lateral condyles of both femora. On the left side the separated bone remains close to its site of origin. In the right knee, the fragment has moved and may be responsible for the ill-defined intra-articular densities, projected between the lateral conyles of right femur and tibia. The endosteal margin is better defined on the right side and this may reflect its greater exposure to intra-articular pressure changes or the density may be due to creeping substitution of newbone over old.

Osteochondromas are cartilage-covered, histologically normal bony projections (exostoses) on the external surface of a bone in the vicinity of growth plates. They are the most common benign bone lesions and present during late childhood and adolescence. Although any bone with enchondral ossification may be involved, the femur, the proximal tibia, and the proximal humerus account for approximately 65-85% of cases. There is a hereditary skeletal dysplasia known as osteochondromatosis (multiple heritable exostoses) where multiple exostoses are distributed symetrically on the skeleton. This is a autosomal-dominant disease and is one of the most common skeletal dysplasias. The condition is familial, with more severe manifestations in men.
