Fig. 5.108a–c


Hemangioma


Fig. 5.109a–c, p. 570


Lipoma


Subcutaneous fat necrosis


Bone tumor


Progressive systemic sclerosis (Thibierge-Weissenbach syndrome)

Fig. 5.107 Myositis ossificans in the vastus medialis after trauma (arrows).
Fig. 5.108a–c Juxtacortical myositis ossificans. (a, b) One month after trauma, a region of extraskeletal ossification has developed adjacent to the proximal fibula (arrow in b). (c) Increased fluid signal intensity is seen between the new bone formation and underlying fibula on T2-weighted MRI (arrow).
Fig. 5.109a–c Hemangioma with phleboliths (a) produces saucerization of the distal fibula. MRI shows avid enhancement and periosteal reaction on T1-weighted fat-suppressed imaging (b) after the administration of gadolinium and the contributions of blood vessels on time-resolved imaging with contrast kinetics (c).

Diagnosis


Findings


Comments


Dermatomyositis


Fig. 5.110


Muscle calcifications.

Increased T2-weighted signal intensity and enhancement in muscles on MRI may help direct area for biopsy.


Connective tissue disorders


Fig. 5.111


Amorphous and punctuate calcifications in the subcutaneous soft tissues.


Vitamin D toxicity




Diastrophic dysplasia


Premature calcification of the cartilage.

Premature costochondral calcification. Scoliosis, clubbed feet, malformed pinnae, cleft palate. Hitchhiker thumb.


Fibrodysplasia ossificans progressiva


Intermittent progressive heterotopic bone replaces skeletal muscle and connective tissues.

Malformations of the great toes.


Progeria


Soft-tissue calcifications.

Precocious senility with early death from coronary artery disease.
