Sarcoma causing impingement of brachial plexus

Case contributed by Dr Shu Su

Presentation

35 years old male with history of sarcoma. Weakness in distal right upper limb.

Patient Data

Age: 35 years
Gender: Male

The large, infiltrative mass centred in the right supraclavicular region remains evident.  There is destruction of the adjacent first rib and infiltration of the trunks and divisions of the brachial plexus. The right subclavian vessels are partially encased.   The mass abuts the undersurface of the right clavicle and extends into the apex of the right lung and abuts the upper 2 thoracic vertebrae. A separate nodule deep to subscapularis causes cortical destruction of the adjacent scapula. 

 

Case Discussion

Malignant soft tissue tumours such as sarcomas may be difficult to differentiate on MRI. Any primary tumour in the vicinity of the brachial plexus may displace, compress or infiltrate the brachail plexus to cause corresponding clinical symptoms. Other evidence of neoplastic disease affecting the brachial plexus includes lymphadenopathy, bony lesions, intrathoracic and chest wall masses 1,2.
