Summary
A rare case of hyperparathyroidism caused isolated neck muscle weakness, leading to head drop. Surgical removal of the parathyroid adenoma resolved symptoms and normalized calcium levels.
Area of Science:
- Endocrinology
- Neurology
- Surgical Case Report
Background:
- Hyperparathyroidism typically presents with hypercalcemia and related symptoms.
- Muscle weakness can occur in hyperparathyroidism, but isolated cervical and dorsal paravertebral muscle weakness is rare.
Observation:
- A 73-year-old female presented with inability to maintain an upright head posture after minimal exertion.
- This symptom was attributed to isolated weakness of the cervical and dorsal paravertebral muscles.
Findings:
- Ultrasound, pathological examination, and parathyroid hormone assays confirmed a parathyroid adenoma.
- Surgical resection of the adenoma led to the complete resolution of head drop and normalization of serum calcium and phosphorus levels.
Implications:
- This case highlights an unusual presentation of hyperparathyroidism.
- It suggests that parathyroid adenoma should be considered in the differential diagnosis of unexplained isolated muscle weakness, particularly affecting the neck and back.
