Study Design:
A case report of purely epidural foraminal cervical cavernous angioma assessed by magnetic resonance imaging and diagnosed at pathologic study.
Objective:
To illustrate a rare cause of cervical foraminal mass mimicking a schwannoma.
Summary Of Background Data:
Several cases of epidural cavernous angioma have been reported. A purely epidural cavernous angioma in a cervical foramen has never been reported in the literature.
Method:
A 36-year-old man sought treatment for acute weakness in his right upper limb with radicular distribution. On magnetic resonance images, the lesion appeared as a foraminal mass with no bone invasion or hematic components. It enhanced after intravenous administration of Gadolinium. Pathologic study after surgery showed a typical cavernous angioma.
Results:
The patient improved slightly after surgery.
Conclusion:
Clinical and radiologic presentation could be confusing in a purely foraminal epidural cervical cavernous hemangioma. Cavernous hemangioma must be known as a differential diagnosis of a foraminal schwannoma. Diagnosis of cavernous angioma is made easily on pathologic examination.
