mDIXON TSE in a patient with brachial plexopathy

Case Study
Verbist, Berit, M.D., Ph.D. Leiden University Medical Centre • Netherlands

Patient history

An 88-year-old female presented with painful progressive paralysis of the right arm.

She had a history of breast carcinoma on the right 6 years earlier, which was treated with mastectomy. Five years ago she underwent radiotherapy for a local recurrence.

 

MR examination

Ingenia 3.0T with dS HeadNeckSpine coil was used.

Scan time for the T2-weighted mDIXON TSE scan was 5:41 min. For the contrast-enhanced T1W mDIXON TSE scan, the scan time was 6:23 min.

Scans were optimized for high image quality rather than speed.

In the right brachial plexus, MR images show thickening and high intensity in cervical roots C5, C6 and C7 extending to the lateral and posterior cords (white arrows).

A parasternal lymph node (arrow head) and an enhancing lesion in the sternum (black arrow) are also noted. Note also an enlarged multinodular thyroid gland. (sa: subclavian artery).

Diagnosis

MRI with DIXON TSE reveals pathologic changes to the brachial plexus and other abnormalities.

Biopsy has confirmed recurrence of the breast cancer. The diagnosis is lymphatic and hematogenous tumor spread.

Clinical impact of mDIXON TSE

The mDIXON TSE images provide homogeneous fat suppression in a large field of view, even in areas with air-bone-soft tissue interfaces. This delivers good visualization of the lower neck region and thoracic inlet.
