AI Article Synopsis
- The study highlights the challenges of anesthetic management in patients with catecholamine-secreting glomus jugulare tumors, particularly those with significant intracranial extension.
- Both patients treated with magnesium sulfate showed improved hemodynamic stability during surgery, contrasting with traditional methods like sodium nitroprusside.
- The findings suggest that magnesium sulfate could effectively minimize blood pressure fluctuations during tumor excision, indicating its potential as a valuable option in these cases.
Article Abstract
Purpose: Catecholamine-secreting glomus jugulare tumours are uncommon and their anesthetic management can be challenging. The authors present the first description of the use of magnesium sulfate in the management of two patients with catecholamine-secreting glomus jugulare tumours where there was significant intracranial extension.
Clinical Features: Patient 1 underwent a transmastoid transoccipital excision of a catecholamine-secreting glomus tumour. He exhibited marked hemodynamic instability after handling of the tumour began, which was not controlled by sodium nitroprusside. Improved hemodynamic stability was seen after the patient received magnesium sulfate. Patient 2 also underwent a transmastoid transoccipital excision of a catecholamine-secreting glomus tumour. Magnesium sulfate was commenced prior to tumour handling and continued until the tumour was removed. The patient remained hemodynamically stable. Sodium nitroprusside was not required.
Conclusion: Magnesium sulfate may be useful in preventing or minimizing the blood pressure changes associated with handling during excision of catecholamine-secreting glomus jugulare tumours. It may be of particular benefit in patients where there is significant intracranial extension.

Salvage Radiosurgery After Subtotal Resection for Catecholamine-secreting Jugular Paragangliomas: Report of Two Cases and Review of the Literature.

Objectives: Catecholamine-secreting jugular paragangliomas (JPs) represent a rare subset of head and neck paragangliomas that may present with hypertension, arrhythmia, or syncopal episodes. Subtotal resection to protect critical neurovascular structures may result in persistent catecholamine excess from residual tumor. Herein, we report our experience with stereotactic radiosurgery (SRS) for salvage treatment of catecholamine-secreting JP following subtotal microsurgical resection.

Objectives: Paragangliomas of the head and neck and cranial base are typically benign, slow-growing tumors arising within the jugular foramen, middle ear, carotid bifurcation, or vagus nerve proper. The objective of this study was to provide a comprehensive characterization of our institutional experience with clinical management of these tumors and posit an algorithm for diagnostic evaluation and treatment.
Methods: This was a retrospective cohort study of patients undergoing treatment for paragangliomas of the head and neck and cranial base at our institution from 2000-2017.

OBJECTIVE Glomus jugulare tumors are rare indolent tumors that frequently involve the lower cranial nerves (CNs). Complete resection can be difficult and associated with lower CN injury. Gamma Knife radiosurgery (GKRS) has established its role as a noninvasive alternative treatment option for these often formidable lesions.

To treat patients with a catecholamine-secreting glomus jugulare tumor, perioperative management is important. Perioperative catecholamine hypersecretion causes severe problems in the treatment of a catecholamine-secreting glomus tumor. Therefore, a precise therapeutic strategy and perioperative management are required through collaboration of the endocrinology, anesthesiology, and endocrine surgery departments .

Secretory glomus jugulare tumors are often resected surgically to control the systemic effects of the catecholamines they produce. This involves complex skull base surgery, which carries significant risks and frequent morbidity. Stereotactic radiosurgery (SRS) is a recently recognized treatment for glomus jugulare tumors, though little is known about its use in secretory tumors.
