Schwannoma (brachial plexus)
From the case:
Schwannoma (brachial plexus)
MRI
Loading images...
Axial T1
Selected images from an MRI of the brachial plexus demonstrate a very well circumscribed enhancing lesion inline with the brachial plexus. A second elongated enhancing lesion along the C7 nerve root suggests that both lesions are schwannomas.
Case Discussion
The patient went on to have a biopsy which confirmed the diagnosis of a schwannoma. The presence of a second probable schwannoma on the right C7 nerve root raises the possibility of neurofibromatosis type 2.
