Summary
Parathyroid carcinoma, a rare cancer, can metastasize to the brain. Aggressive surgical removal of the tumor successfully treated a patient with intracranial metastasis, resolving hypercalcemia and improving symptoms.
Area of Science:
- Endocrinology
- Neurosurgery
- Oncology
Background:
- Parathyroid carcinoma is a rare endocrine malignancy with high recurrence rates and mortality often due to hypercalcemia.
- Intracranial metastasis from parathyroid carcinoma is exceptionally rare, with limited documented cases.
Observation:
- A 44-year-old man presented with hypercalcemia and leg weakness 4 years post-parathyroidectomy for parathyroid carcinoma.
- Imaging revealed an isolated intracranial mass with elevated parathyroid hormone levels, indicating metastatic disease.
Findings:
- The patient underwent successful resection of the intracranial mass using frameless stereotactic MRI-guided surgery.
- Pathological examination confirmed parathyroid carcinoma metastasis.
- Post-surgery, the patient's hypercalcemia and neurological symptoms resolved.
Implications:
- This case highlights the importance of considering metastatic parathyroid carcinoma in patients with a history of the disease presenting with hypercalcemia and neurological deficits.
- Aggressive surgical management of metastatic parathyroid carcinoma can lead to favorable outcomes and prevent life-threatening metabolic complications.
- Intraoperative MRI is a valuable tool for ensuring complete tumor resection in complex neurosurgical cases.
