Imaging plays a major role in the management of ankle and foot problems. Most conditions are assessed by plain
films alone. MRI is an excellent technique for those cases where the diagnosis is uncertain as it can exclude most
clinically relevant pathologies. Ultrasound is an excellent tool for imaging focal soft tissue abnormalities. CT is
occasionally useful when bony detail is required. Bone scintigraphy has a limited role and has been largely replaced by MRI in many centres. The main reasons for referral are swelling and pain. Many conditions of the ankle and foot are related acute or repetitive trauma.
# Plain films are useful as an initial screen test for diffuse ankle and foot pain.
# MRI is the most suitable technique for global assessment of bone and soft tissues for persistent pain following injury.
# Ultrasound should be reserved for specific focal soft tissue conditions and when dynamic information is required.
# Ultrasound is an excellent technique for guiding injections.
A sarcoma (from the Greek sarx (σάρκα) meaning "flesh") is a cancer that arises from transformed cells of mesenchymalorigin. Thus, malignant tumors made of cancerous bone, cartilage, fat, muscle, vascular, or hematopoietic tissues are, by definition, considered sarcomas. This is in contrast to a malignant tumor originating from epithelial cells, which are termedcarcinoma. Human sarcomas are quite rare.[citation needed] Common malignancies, such as breast, colon, and lung cancer, are almost always carcinoma.
Fibromas (or fibroid tumors or fibroids) are benign tumors that are composed of fibrous or connective tissue. They can grow in all organs, arising from mesenchyme tissue. The term "fibroblastic" or "fibromatous" is used to describe tumors of the fibrous connective tissue. When the term fibroma is used without modifier, it is usually considered benign, with the termfibrosarcoma reserved for malignant tumors.
