Patient Data
Age: 45 years
Gender: Female
From the case:
Jugular foramen schwannoma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_pin":false},"extraPropsURL":"/studies/79634/annotated_viewer_json?iframe=true\u0026lang=us"}
Bilobed predominantly low density mass extends from the posterior fossa through the left jugular foramen and into the neck with smooth expansion of the left jugular fossa.
From the case:
Jugular foramen schwannoma
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_pin":false},"extraPropsURL":"/studies/79635/annotated_viewer_json?iframe=true\u0026lang=us"}
Partial resection of the mass was performed between the CT and the MRI. Residual well-defined lobulated mass extending through the jugular foramen with cystic components. Atrophy of the left side of the tongue has developed since the CT in keeping with interval left hypoglossal nerve palsy (denervation).
Case Discussion
Left jugular foramen schwannoma (histologically confirmed) with typical appearance of smooth expansion of the jugular foramen and cystic degeneration.
