Carotid paragangliomas are infrequent tumors whose biology and natural history are unpredictable
in a significant number of cases. Such infrequency and the different ways they manifest themselves
pose a diagnostic/therapeutic challenge that is reflected in the final outcomes.
Seventy-five percent of carotid paragangliomas adopt simple forms (single tumors measuring
<4 cm, defined and resectable, non-secretory and benign); with expert treatment, this normal
presentation leads to excellent results. The remaining 25% are complex forms (bilateral, large,
attached to the carotids, functional, malign, associated with other pathologies, etc); morbidity and
mortality rates in these cases are clearly different. Within this complex group, there are a number of
carotid pathologies (e.g., symptomatic stenosis or aneurysms) that are synchronous and ipsilateral
to the paraganglioma.
This review sets out to address these situations in a unitary manner, with its references being very
widely distributed in the literature, with the aim being to highlight their idiosyncrasies of diagnostic
and therapeutic interest. This has involved a systematic literature review of the Medline and
Cochrane Library databases, up to 1 November 2019. This has located 12 articles with a total of 15
Conclusion: Patients with these exceptional combinations are more complex and constitute a
twin challenge: a) diagnostic (search for associations), and b) therapeutic (surgical times and
prioritizations), with the aim being to avoid errors and achieve the best end results.
