title: A mediastinal mass presenting with unilateral periscapular and arm pain.
abstract: We describe a case of a patient with mediastinal lymphoma who presented with arm and scapular pain, which is an atypical referral pattern for pain originating from the mediastinum. We use this case as a platform to discuss mediastinal pain referral patterns and the importance of maintaining a broad differential diagnosis of arm and scapular pain, especially when symptoms atypical of pure neuromusculoskeletal structural disease are present.
