A Pancoast tumor is a tumor of the apex of the lung. It is a type of lung cancer defined primarily by its location situated at the top end of either the right or left lung. It typically spreads to nearby tissues such as the ribs and vertebrae. Most Pancoast tumors are non-small-cell lung cancers . The growing tumor can cause compression of many ...
A Bankart lesion is a type of shoulder injury that occurs following a dislocated shoulder. [ 3] It is an injury of the anterior ( inferior) glenoid labrum of the shoulder. [ 4] When this happens, a pocket at the front of the glenoid forms that allows the humeral head to dislocate into it.
Adhesive capsulitis (AC), also known as frozen shoulder, is a condition associated with shoulder pain and stiffness. [ 1] It is a common shoulder ailment that is marked by pain and a loss of range of motion, particularly in external rotation. [ 3] There is a loss of the ability to move the shoulder, both voluntarily and by others, in multiple ...
However, imaging studies are unable to show cause of shoulder pain in diagnosing. For example, MRI imaging would show rotator cuff pathology and bursitis but is unable to specify the cause. [15] On physical exam, the physician may twist or elevate the patient's arm to test for reproducible pain (the Neer sign and Hawkins-Kennedy test).
The most significant impact of magnetic resonance neurography is on the evaluation of the large proximal nerve elements such as the brachial plexus (the nerves between the cervical spine and the underarm that innervate shoulder, arm and hand), [9] the lumbosacral plexus (nerves between the lumbosacral spine and legs), the sciatic nerve in the pelvis, [10] as well as other nerves such as the ...
Syringomyelia is a generic term referring to a disorder in which a cyst or cavity forms within the spinal cord. Often, syringomyelia is used as a generic term before an etiology is determined. [ 3] This cyst, called a syrinx, can expand and elongate over time, destroying the spinal cord. The damage may result in loss of feeling, paralysis ...
CT scan and X-ray show lytic expansion lesions with clear borders. [1] MRI reveals fluid levels. [1] Treatment is usually by curettage, bone grafting or surgically removing the part of bone. [2] 20–30% may recur, usually in the first couple of years after treatment, particularly in children. [2] It is rare. [3]
003335. Magnetic resonance imaging ( MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ...
