Overview

Collet Sicard Syndrome, also known as condylar jugular syndrome, describes a collection of ipsilateral cranial nerve palsies (IX, X, XI, and XII) as a result of injury or mass effect at the skull base.

History

Frederic Collet first described a World War I patient in 1915 with this constellation of cranial nerve palsies following a bullet injury. This case presentation was seen again by Jean Sicard in 1917.

Diagnosis

Differential Diagnosis

There are several named syndromes differentiating the various cranial nerve deficits that can result from skull base masses and lesions. These should be considered based on cranial nerve involvement.

• Vernet Syndrome
• Villaret Syndrome
• Tapia Syndrome
• Jackson Syndrome
• Schmidt Syndrome

These syndromes and their respective cranial nerve involvement are outlined in the table below.
