Study design: Case Report
Abstract: INTRODUCTION: Carotid body tumor (CBT) is one of the most common paragangliomas in the head and neck region, accounting for only 0.6 % of tumors in this area. Here, we present a rare case of CBT associated with congenital complete heart block (CHB). CASE PRESENTATION: We report the case of a 47-year-old female with a history of left neck and ear pain, accompanied by a gradually enlarging neck mass over 2.5 years. Following initial evaluations and multiple differential diagnoses, CT angiography revealed an oval-shaped mass measuring 30 × 50 mm at the left carotid bifurcation, confirming a Shamblin type II CBT. Preoperative assessments demonstrated congenital CHB on electrocardiogram and echocardiography. The patient underwent complete tumor resection with all necessary precautions, including temporary pacemaker placement and careful monitoring. CLINICAL DISCUSSION: CBTs are considered rare neoplasms, comprising only 0.6 % of head and neck tumors and approximately 0.03 % of all neoplasms. The surgical outcomes demonstrated that despite the coexistence of a CBT with CHB, safe and successful surgery is possible with careful planning and comprehensive management. CONCLUSION: This case highlights the importance of precise diagnosis and management in rare combination cases and emphasizes the crucial role of collaboration between vascular surgery and anesthesiology specialists in minimizing surgical risks and improving patient quality of life.
