Myopathy with multiple central cores. A case with hypersensitivity to pyrexia

Area of Science:

• Neurology
• Genetics
• Muscle Physiology

Background:

• Proximal muscle weakness is a common pediatric complaint.
• Febrile episodes can exacerbate various neuromuscular disorders.
• Central core disease is a rare congenital myopathy.

Observation:

• An eight-year-old male presented with progressive proximal muscle weakness.
• Symptoms worsened significantly during febrile illnesses.
• Neuromuscular evaluation revealed a myopathy characterized by multiple central cores.

Findings:

• The patient's myopathy was non-familial.
• Histological examination showed characteristic central cores within muscle fibers.
• The presence of central cores was noted in this patient.

Implications:

• The findings suggest a potential link between central core myopathy and malignant hyperpyrexia.
• Further research may elucidate a common pathophysiological mechanism.
• Understanding this connection could improve diagnosis and treatment strategies for both conditions.
