Disseminated thrombosis of the internal jugular vein, superior ophthalmic vein and cavernous sinus as the primary manifestation of occult malignancy: a case report

ABSTRACT

Internal jugular vein (IJV) thrombosis is a life-threatening condition most often associated with local risk factors such as head or neck infection or central venous catheterisation. Underlying malignancy is a rare but important aetiology to consider in patients presenting with spontaneous IJV thrombosis. We describe a case of necrotic cervical lymphadenopathy with thrombosis of the IJVs, cavernous sinuses and superior ophthalmic veins in a patient with metastatic squamous cell carcinoma, which was further complicated by an orbital compartment syndrome. The differential diagnosis of IJV thrombosis includes a range of infective, metastatic and thrombophilic pathologies. This case illustrates that, in the absence of an underlying precipitating factor, spontaneous IJV thrombosis should prompt further systemic investigations. Furthermore, patients with thrombotic events affecting the orbital venous drainage system should be monitored closely for signs of an acute orbital compartment syndrome.
