Study Objective. To describe the clinical presentation, evaluation, and treatment of a hypoglossal schwannoma. Methods. We report an unusual case of a hypoglossal schwannoma presenting as a pulsatile level II neck mass at the bifurcation of the external and internal carotid arteries, mimicking a carotid body tumor. Radiologic findings are reviewed in detail. Results. A 59-year-old female presen...

Introduction: Arteriovenous malformations (AVMs) are uncommon vascular lesions that can arise in any part of the body. Case Report: In this case study, we presented a huge AVM of the upper lip in a 70-year-old man that he noticed since 5years ago with slow growth in this period. Computed tomography angiography revealed a large AVM with feeders from the right...

Two patients developed carotid sinus syndrome following embolization procedures. One patient had undergone balloon occlusion of the internal carotid artery; in the other patient, embolization of a carotid body tumor had been performed. The method of diagnosis as well as the etiology and treatment are discussed.

The causes of syncope are diverse and extensive; carotid body tumors are an extremely rare cause of syncope. These rare neoplasms represent less than 0.5% of all head and neck tumors. The authors present a case of a woman with syncope who was found to have a right-sided carotid body tumor. After surgical resection was performed, she did not have any additional syncopal or near-syncopal events. ...

Carotid body tumors are rare, slow-growing, hypervascular neuroendocrine tumors. Although these tumors are benign neoplasm, they also have a tendency to malignant transformation. Complete surgical excision is the gold standard therapeutic modality for the treatment of carotid body tumors. Early surgical removal is recommended to prevent the development of larger and more advanced tumors, which ...

BACKGROUND Carotid body tumors are rare, highly vascularized neoplasms that arise from the paraganglia located at the carotid bifurcation. Surgery is the only curative treatment. However, treatment of bilateral carotid body tumors represents a special challenge due to potential neurovascular complications. CASE REPORT We present the therapeutic management of a 34-year-old woman with bilateral...
