What is muscle infarction?
BACKGROUND: Muscle infarction is a rare complication of spontaneous ischemic necrosis occurring in skeletal muscle. It is particularly common in patients with diabetes who have impaired sugar regulation. However, muscle infarction is frequently misdiagnosed due to varied clinical manifestations.
What does a muscle infarction feel like?
Signs and symptoms Decreased or no pulse in an arm or leg beyond the site of blockage. Pain in the affected area. Muscle spasm in the affected area. Numbness and tingling in an arm or leg.
What is diabetic myositis?
Diabetic myonecrosis is a rare but serious complication of long-standing diabetes mellitus (DM), commonly associated with diabetic nephropathy and retinopathy. It is caused by infarcted muscle tissue, usually in the thigh. The most common presentation is abrupt onset of unilateral pain, tenderness, and edema.
Can diabetes cause myositis?
Diabetic muscle infarction is a rare cause of acute severe muscle pain in patients with diabetes mellitus. The differential diagnosis includes focal or systemic myositis, localised abscess, haematoma, deep venous thrombosis, osteomyelitis, and a muscle tumour (sarcoma or lymphoma).
How does infarction occur?
Infarction is tissue death (necrosis) due to inadequate blood supply to the affected area. It may be caused by artery blockages, rupture, mechanical compression, or vasoconstriction. The resulting lesion is referred to as an infarct (from the Latin infarctus, “stuffed into”).
Can diabetes cause cramping muscles?
Muscle cramping is a relatively common manifestation of DM. It can be the result of electrolyte imbalances, hypoglycemia, peripheral vascular disease with arterial insufficiency, and/or peripheral neuropathies. The cramps tend to be more common in the lower extremities and may be seen more commonly at night.
Does infarction hurt?
Chest pain is the most common presenting complaint of acute myocardial infarction. The classic manifestation of ischemia is usually described as a heavy chest pressure or squeezing, a “burning” feeling, or difficulty in breathing. The discomfort or pain often radiates to the left shoulder, neck, or arm.
What does muscle death look like?
The “classic triad” of rhabdomyolysis symptoms are: muscle pain in the shoulders, thighs, or lower back; muscle weakness or trouble moving arms and legs; and dark red or brown urine or decreased urination. Keep in mind that half of people with the condition may have no muscle-related symptoms.
What causes diabetic Amyotrophy?
What causes diabetic amyotrophy? Diabetic amyotrophy is thought to be caused by an abnormality of the immune system, which damages the tiny blood vessels which supply the nerves to the legs. This process is called microvasculitis.
Can high sugar levels cause muscle pain?
Over time, uncontrolled diabetes can affect the muscles and skeleton, leading to joint pain, nerve damage, and other symptoms.
Is there a difference between infarct and infarction?
86 What is the difference between an infarct and infarction? An infarct is an area of ischemic necrosis. Infarction is the process that leads to this ischemic necrosis.
What is diabetic muscle infarction?
DISCUSSION Diabetic muscle infarction is an unusual complication of diabetes mellitus. The apparent rarity of this condition may make it difficult for clinicians and radiologists to become familiar with this entity, but diabetic muscle infarction is a distinctive illness that can be easily recognized.
Which MRI findings are characteristic of intramuscular inflammatory infiltration?
MRI shows hyperintense signal and enhancement on STIR and fat-saturated gadolinium-enhanced T1-weighted images caused by both diffuse inflammatory infiltrates and collagenization of intramuscular paraseptal fasciae ( Fig. 6 ).
Is MRI a useful tool for the diagnosis of muscle diseases?
CONCLUSION. MRI is a highly sensitive tool for the diagnosis of muscle diseases. Although it has low specificity, awareness of the potential imaging findings in the various, sometimes rare, muscular disorders is helpful for accurate diagnosis.
