Internal jugular vein tumor thrombus due to parapharyngeal extraosseous plasmacytoma

Catarina Oliveira et al. Radiol Case Rep. .

Abstract

Tumor thrombosis of the internal jugular vein (IJV) represents an uncommon event, usually in the setting of underlying thyroid neoplasms. Extraosseous plasmacytoma (EMP) with tumor thrombosis of the IJV has not yet been reported in the literature. We present a unique case of a plasmacytoma in the left parapharyngeal space with direct extension to the left IJV, documented with contrast enhanced computed tomography and US Doppler. Presence of avid thrombus enhancement allowed differentiation between tumoral extension and thrombothic changes.

Keywords: CT, computed tomography; IJV, internal jugular vein; Jugular vein; MRI, magnetic resonance imaging; PET/CT, positron emission tomography/computed tomography; Plasmacytoma; Tumoral thrombus.
