Jugular foramen schwannoma

Jugular foramen schwannomas are a rare type of intracranial schwannoma that presents as a jugular fossa mass. As the name implies it involves the jugular foramen.

In those without neurofibromatosis type 2 (NF2), they tend to present between the 3rd to 6th decades of life. There is a recognised female predilection 1. The tumours can have a wide variety of clinical presentations.

They can arise from cranial nerves IX, X or XI, with IX being the most common 3.

Associations
CT
  • usually well demarcated
  • tend to be iso to hypo attenuating to brain parenchyma 3
  • may show expansion and remodelling of the affected jugular foramen
  • may have a characteristic dumbbell configuration

Signal characteristics are those of a schwannoma:

  • T1: typically low signal
  • T2: typically high signal
  • T1 C+ (Gd)
    • smaller lesions demonstrate intense homogeneous enhancement
    • larger lesions tend to have heterogeneous enhancement

As with most schwannomas they are generally slow growing tumours. Surgical resection is often the treatment of choice.
