Intrathoracic spindle cell lipoma causing thoracic outlet syndrome

Abstract

A 56-year-old male presented with three years of worsening right arm pain and paresthesias, consistent with thoracic outlet syndrome. Brachial plexus MRI demonstrated a giant extra-pleural lipoma in the right supraclavicular fossa extending within the ipsilateral posterior mediastinum and compressing the neurovascular bundle. Pathology determined this to be a rare spindle cell lipoma. We present an exceedingly rare, centrally-located giant spindle cell lipoma that precipitated thoracic outlet syndrome.
