Multiple Primary Thyroid Cancer
 in combination with Malignant
 Paraganglioma of the Neck
 complicated by Acute Cerebrovascular
 Event in the Postoperative Period:
 Clinical Case

Abstract

Actuality: Paraganglioma originates from the nerve
 ganglia along a.carotis, the ganglion of n.vagus, and the
 nerve plexuses around the sigmoid sinus, and has a rich
 tumor vasculature. Paraganglioma accounts for 0.8% of all
 CNS tumors and occurs most often at 40-60 years. Chemodectoma is located in the common carotid artery bifurcation zone and accounts for 2/3 of all glomus tumors.
 Purpose: The article describes a clinical case of multiple primary thyroid cancer in combination with malignant
 paraganglioma of the neck complicated by acute cerebrovascular event (ACE) in the postoperative period treated at
 the Head and Neck Tumor Center of the Kazakh Institute of
 Oncology and Radiology.
 Results: The presented clinical case demonstrates the
 results of the treatment of multiple primary cancer complicated by an ACE in the postoperative period. The qualification of doctors, adequate diagnostics contributed to choosing the right ACE treatment tactics taking into account all
 the patient-specific features, the tumor localization, and
 possible postoperative complications.
 Conclusion: The presented clinical case confirms the
 available data on the necessity of all diagnostic procedures
 and their effectiveness in the assessment of the prevalence
 of the process and the involvement of the adjacent anatomical structures in the suspected chemodectoma to avoid
 postoperative consequences that can lead to disability and
 fatal outcome. A wrong choice of the volume of surgical intervention can result in severe postoperative complications.
 Timely diagnosis and knowledge of the clinical course of the
 ACE helped restore the patient’s general condition and stop
 signs of cerebral ischemia. Successful recovery of a patient
 depends on the qualifications of the doctors and the prevalence of the tumor process. Adequate symptomatic therapy
 has a huge impact on the course of a complicated postoperative period.
