Electromyographic changes in a patient with hypocalcemia after thyroidectomy: A case report

Area of Science:

• Neurology
• Endocrinology
• Clinical Medicine

Background:

• Hypocalcemia is an uncommon outpatient condition with diverse, often ambiguous, clinical manifestations.
• Muscle cramps and tetany are potential signs of nerve hyperexcitability linked to low calcium levels.
• The direct causal link between hypocalcemia and specific symptoms can be challenging to establish.

Observation:

• A 59-year-old female patient presented with persistent muscle pain and cramping in her extremities.
• Electromyographic (EMG) studies were performed to investigate the cause of her symptoms.
• The EMG study revealed characteristic changes indicative of neuromuscular dysfunction.

Findings:

• Electromyographic findings confirmed neuromuscular hyperexcitability.
• These changes were directly attributed to documented hypocalcemia.
• The case illustrates a clear association between low calcium levels and specific electrophysiological abnormalities.

Implications:

• This case underscores the importance of considering hypocalcemia in patients presenting with unexplained muscle cramps and pain.
• Electromyography can be a valuable diagnostic tool for identifying hypocalcemia-induced neuromuscular excitability.
• Early diagnosis and management of hypocalcemia are crucial for alleviating symptoms and preventing complications.
