A previous bone fracture that is now healed. No further follow-up or evaluation is needed for this finding.
A lymph node is a small bean-shaped structure that is part of the body's immune system. Lymph nodes can be “swollen” (reactive) on imaging. Anything that causes inflammation can cause reactive lymph nodes. Most often this is from a transient viral infection; other less common causes include bacterial infection, malignancy, autoimmune disorders, as well as medications.
Rectal duplication cysts are rare, congenital (present from birth) malformations of the gastrointestinal tract.
The sigmoid colon is the part of the large intestine that is closest to the rectum and anus. When the sigmoid colon is longer than usual and coils onto itself, it is known as a redundant sigmoid colon.
Urinary tract infections (UTIs) happen when bacteria goes into the urethra (the final tube that empties urine from the body) and travels into the bladder. If the infection continues traveling past the bladder and into the kidneys, it is called pyelonephritis (a kidney infection). Both bladder and kidney infections are more common in women than men because of the shorter urethra length. Symptoms and signs of pyelonephritis include blood in the urine, burning with urination, the need to urinate frequently, fever/chills, flank/back pain and nausea/vomiting.
Bone marrow is the tissue inside bones that forms the various blood cell types. Marrow is mainly “red marrow” in babies, and over decades, as fat normally replaces part of the marrow, it becomes “yellow marrow.” Yellow marrow can turn back into red marrow when there is increased oxygen demand. This can be seen in athletes (such as marathon runners), heavy cigarette smokers and people with congenital red blood cell problems (such as sickle cell disease).
