Overview
History and Symptoms
The symptoms experienced in cholesterol embolism depend largely on the organ involved. Non-specific symptoms often described are fever, muscle ache and weight loss. Embolism to the legs causes a mottled appearance and purple discoloration of the toes, smalls infarcts and areas of gangrene due to tissue death that usually appear black, and areas of the skin that assume a marbled pattern known as livedo reticularis.[1]
Kidney involvement leads to the symptoms of renal failure, which are non-specific but usually cause nausea, reduced appetite (anorexia), raised blood pressure (hypertension), and occasionally the various symptoms of electrolyte disturbance such as an irregular heartbeat. Some patients report hematuria (bloody urine) but this may only be detectable on microscopic examination of the urine. Increased amounts of protein in the urine may cause edema (swelling) of the skin (a combination of symptoms known as nephrotic syndrome).[1]
If emboli have spread to the digestive tract, reduced appetite, nausea and vomiting may occur, as well as nonspecific abdominal pain, gastrointestinal hemorrhage (vomiting blood, or admixture of blood in the stool), and occasionally acute pancreatitis (inflammation of the pancreas).[1]
Both the central nervous system (brain and spinal cord) and the peripheral nervous system may be involved. Emboli to the brain may cause stroke-like episodes, headache and episodes of loss of vision in one eye (known as amaurosis fugax).[1] Emboli to the eye can be seen by ophthalmoscopy and are known as plaques of Hollenhorst.[2] Emboli to the spinal cord may cause paraparesis (decreased power in the legs) or cauda equina syndrome, a group of symptoms due to loss of function of the distal part of the spinal cord - loss of control over the bladder, rectum and skin sensation around the anus.[1] If the blood supply to a single nerve is interrupted by an embolus, the result is loss of function in the muscles supplied by that nerve; this phenomenon is called a mononeuropathy.[1]
- CES may resemble a systemic vasculitis like PAN, with multiple scattered areas of ischemic damage, with skin, renal, extremity, intestinal, and neurologic manifestations.
