Collet-Sicard Syndrome from Thrombosis of the Sigmoid-Jugular Complex : A Case Report and Review of the Literature

Abstract EN

Purpose.

Collet-Sicard syndrome is a very rare condition characterised by unilateral palsy of the IX–XII cranial nerves.

It is distinguished from Villaret syndrome by lack of presence of sympathetic involvement.

Current literature contains only two cases of Collet-Sicard syndrome due to idiopathic internal jugular vein thrombosis.

Method and Results.

We report the case of Collet-Sicard syndrome in a 30-year-old man who presented with delayed development of XIth nerve dysfunction, due to internal jugular vein-sigmoid sinus thrombosis.

A multidisciplinary team approach was employed in the management of this patient.

At three-month followup, he had significantly improved swallowing, and repeat computed tomography neck scan showed partial recanalisation of the right internal jugular vein.

Conclusion.

In suspected Collet-Sicard syndrome, a focal primary lesion or metastasis to the temporal bone must be excluded, and sigmoid-jugular complex thrombosis should be considered in the differential diagnosis.

Early recognition and treatment may result in significant functional recovery.
