What causes lesions on the sternum?
Causes of bone lesions include infections, fractures, or tumors. When cells within the bone start to divide uncontrollably, they are sometimes called bone tumors. Most bone lesions are benign, meaning they are not cancerous. Some bone lesions are cancerous, however, and these are known as malignant bone tumors.
What is sternoclavicular syndrome?
Sternocostoclavicular hyperostosis (SCCH) is a chronic inflammatory disorder which presents with erythema, swelling, and pain of the sternoclavicular joint. Approximately one half of patients have acne or pustular lesions with the best described association being with palmoplantar pustulosis (PPP).
What is manubrium of the sternum?
The manubrium is the most massive, thickest, and squarest of three main sternal elements. It is the superior-most element of the sternum and is the widest part of this bone. b. Clavicular notches occupy the superior corners of the sternum. It is here that the manubrium articulates with the right and left clavicles.
What does a sternum MRI show?
Growths, such as a mass or tumor: An MRI may show a growth in your sternum (breastbone) or ribs or in the muscles of your chest. An MRI may show if you have a lump in your lung or breast. An MRI may be done to check for growths if another test, such as a mammography, showed a problem.
What causes a lump on the sternoclavicular joint?
Common causes of SCCJ swelling include degenerative osteoarthritis, septic arthritis, rheumatoid arthritis, crystal deposition disorders, metastatic disease and post-operative involvement after surgery on the neck (1).
What bone is the manubrium on?
the sternum
The manubrium (Latin for “handle”) is the broad upper part of the sternum. It has a quadrangular shape, narrowing from the top, which gives it four borders. The suprasternal notch (jugular notch) is located in the middle at the upper broadest part of the manubrium. This notch can be felt between the two clavicles.
Is sternum and manubrium same?
The sternum is a partially T-shaped vertical bone that forms the anterior portion of the chest wall centrally. The sternum is divided anatomically into three segments: manubrium, body, and xiphoid process. The sternum connects the ribs via the costal cartilages forming the anterior rib cage.
Which is better MRI or CT scan for chest?
MRI is best when the images need to be very detailed, looking for cancer, causes of dementia or neurological diseases, or looking at places where bone might interfere. Chest – CT is much better at examining lung tissue and often used for follow up on abnormal chest x-rays.
How do you know if a bone lesion is benign or malignant?
Benign lesions form in a bone and can grow locally but do not spread to other organs to cause harm. Malignant lesions, more commonly referred to as cancer, are lesions which may form and develop in the bone but have the capacity to spread to other areas of the body and continue to grow.
What does a lump on your clavicle mean?
If not a fracture, it could be due to an infection, a cyst or tumor, or an enlarged lymph node. A collarbone injury, such as a fracture or break, can sometimes cause a lump to form. The injury can range in severity from a simple fracture to a complex break that separates the bone into several pieces.
What is sternoclavicular synovitis?
The sternoclavicular joint is a true synovial joint, and is therefore susceptible to the normal spectrum of inflammatory and degenerative arthritides, as well as a number of other disorders which are unique to the joint. Such disorders can present either acutely or insidiously with localised pain and swelling.
