CTICasesSupraclavicular Schwannoma
Imaging findings
CT chest shows a well-defined, homogeneous, hypervascular soft tissue mass located in the left supraclavicular apex, overlying the left clavicle and arising from the brachial plexus, representing a schwannoma.
Key takeaways
Schwannomas are benign, slow-growing nerve sheath tumors. In the thoracic outlet or apex, they can present as asymptomatic, well-circumscribed supraclavicular masses, which must be differentiated from apical lung cancers (Pancoast tumors) or lymphadenopathy.
