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 Department 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.
