Abstract:
A 61-year-old woman with newly diagnosed anaplastic thyroid cancer and known metastases to the brain, lungs, and adrenal glands complained of groin muscle pain. F-FDG PET/CT was performed to assess for extent of disease and showed extensive hypermetabolic lesions throughout the skeletal musculature concerning for metastatic disease. As this would be a very rare presentation for anaplastic thyroid carcinoma, a biopsy of the left gluteal muscle was conducted. Pathology demonstrated anaplastic thyroid carcinoma, metastatic to skeletal muscle.

Overview of Skeletal Muscle
Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open....
Disorders of the Skeletal Muscle
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
