Endovascular treatment for jugulotympanic paraganglioma

Abstract

Introduction: Head and neck paragangliomas are tumors derived from the neural crest constituting less than 0.5 % of head and neck tumors and approximately 0.03 % of all tumors in humans, they exhibit an indolent growth pattern, with a mean time of 4,5 years where the dimensions of the lesion are doubled.

Objective: Show the management of two patients with a diagnosis of head and neck paraganglioma.

Clinical cases: We present two cases with the diagnosis of yugulotimpanic paraganglioma, where we show the evolution according to the therapeutic modality used, with emphasis on the results obtained by combining transarterial percutaneous embolization with radiotherapy, showing satisfactory clinical evolution.

Conclusion: The optimal management strategy in these lesions remains in constant change due to the heterogeneity of the clinical presentation, which leads to late diagnosis. Arteriography is the most sensitive study that can be used to confirm the diagnosis, evaluating the possibility of pre-surgical or curative embolization as the procedure progresses.
