EXTREMITIES
Muscular lesions of the extremities that are recognized by CT include atrophy and suppurative or ossifying myositis (Levinsohn and bryan 1979). The begn tumors include hard fibroma developing from the fascia, lipoma developing from intermuscular fat, and mixoma. Other benign tumors are chondroma and hemangioma.the rhabdomyosaecomas develop from parts other than muscle such as the soft tissue (heelan et al.1979; Weinberger and levinson 1978). Metastatic tumors are are rare in muscles, but mestastatis in the subcutaneous tissue of the abdomen has been reported in cases of liver cancer, ovarian cancer, and malignant melanoma (Dunnick et al 1978).
Unilateral swellings of the extremities that are imaged by CT include proliferative myositis, ischemic muscle, diffuse cellulitis, and lymphedema praecox. Introduction of contrast medium into veins near the lesion has been reported for use in osteomyelitis (berman et al 1979). Acute osteomyelitis, and osteosclerosis are seen in the chronic stage. Lesions in the bone marrow are clearly visualized by CT (Khun and berger 1979). The extension of giant cell tumors to the bone marrow or bone surroundings can also be evaluated by CT. in osseous tumors, CT cross section of osteoid osteoma shows the nidus as a low-density area. Ct is particularly good for the detection of extension of osteosarcoma into the bone marrow and level of new bone information (destoutet et al 2979; De Santos et al.1979). a round cell tumor of the bone has been seen by CT (ginaldi and de Santos 1980).
Lesions generating from the muscle, nerves, blood cessels, or bone are seen by CT in the soft tissues of the extremities. Fibrosarcoma, liposarcoma, neurinoma, synoviosarcoma extraosteal osteosarcoma, chondrosarcoma, embryonal rhabdomyosarcoma, leiomyosarcoma, malignant fibrous, histiocytoma, myxoma, and Ewing’s tumor can be recognized by CT.
In the knee joint, the anterior and posterior cruciate ligaments are visualized by the application of double contrast arthrography, so that abnormalietis of the tendon are recognized (Pavlov et al.1979). popliteal cysts and villonodular synovitis have been reported (Goldberg and genant 1978; Rosenthal et.al 1979). CT has also been used for measuring tibial torsion (jend et al.1980)

EKSTREMITASOtot lesi dari ekstremitas yang diakui oleh CT termasuk atrofi dan suppurative atau ossifying myositis (Levinsohn dan bryan 1979). Tumor begn termasuk fibroma keras yang berkembang dari fasia, lipoma berkembang dari lemak intermuscular, dan mixoma. Tumor jinak lain yang chondroma dan hemangioma.the rhabdomyosaecomas berkembang dari bagian lain otot seperti jaringan lunak (heelan et al.1979; Weinberger dan levinson 1978). Tumor metastasis jarang otot, tetapi mestastatis dalam jaringan subkutan perut telah dilaporkan dalam kasus kanker hati, kanker ovarium dan ganas melanoma (Dunnick et al 1978).Pembengkakan sepihak dari ekstremitas yang digambarkan oleh CT termasuk myositis proliferatif, iskemik otot, menyebar selulitis dan lymphedema praecox. Pengenalan media kontras ke vena dekat lesi telah dilaporkan untuk digunakan dalam osteomielitis (berman et al 1979). Osteomielitis akut, dan osteosclerosis terlihat di panggung kronis. Lesi di sumsum tulang jelas Divisualisasikan oleh CT (Khun dan berger 1979). Perpanjangan dari tumor raksasa sel sumsum tulang atau tulang lingkungan dapat juga dievaluasi oleh CT. di osea tumor, CT penampang osteoid osteoma menunjukkan sarang burung sebagai area kepadatan rendah. CT sangat baik untuk deteksi perpanjangan osteosarkoma ke sumsum tulang dan tingkat informasi tulang baru (destoutet et al 2979; De Santos et al.1979). tumor sel bulat tulang telah dilihat oleh CT (ginaldi dan de Santos 1980).Lesi yang menghasilkan dari otot, saraf, cessels darah, atau tulang terlihat oleh CT di jaringan lunak ekstremitas. Fibrosarcoma, liposarcoma, neurinoma, synoviosarcoma extraosteal osteosarkoma, chondrosarcoma, embryonal rhabdomyosarcoma, leiomyosarcoma, ganas berserat, histiocytoma, myxoma, dan Ewing tumor dapat diakui oleh CT.Di sendi lutut, cruciate ligamen anterior dan posterior Divisualisasikan oleh penerapan arthrography double kontras, sehingga abnormalietis tendon diakui (Pavlov et al.1979). Kista popliteal dan villonodular synovitis telah melaporkan (Goldberg dan genant 1978; Rosenthal et.al 1979). CT juga telah digunakan untuk mengukur torsi tibialis (jend et al.1980)
