Abstract:
Hemihypertrophy is a rare congenital disorder that causes unequal growth of the extremities, trunk, face, or half of the body. We report a case of a 32-year-old woman with hemihypertrophy-related gastrocnemius hypertrophy treated with botulinum toxin A injection. The patient has received two botulinum toxin A injections, and we measured the thickness of the gastrocnemius muscle using ultrasound and measured the maximum circumference around the calf with the patient in the prone position. The patient's maximum calf circumference was reduced by 1 cm. The thickness of the medial head of the gastrocnemius was reduced by 0.3 cm, and the thickness of the lateral head of the gastrocnemius was reduced by 0.6 cm. Botulinum toxin A injection therapy was effective in treating hemihypertrophy-related gastrocnemius hypertrophy.
