Key Objectives

Given a patient with a mediastinal mass, the candidate will diagnose the cause, severity, and complications, and will initiate an appropriate management plan, in particular, differentiate between causes based on compartment location.

Enabling Objectives

Given a patient with mediastinal mass, the candidate will

  1. list and interpret critical clinical findings, including
    1. an appropriate history and physical examination to help determine the most likely cause;
  2. list and interpret relevant investigations, including
    1. laboratory and radiological investigations;
  3. construct an effective initial management plan, including:
    1. determining if the patient requires further investigation;
    2. referral of the patient for specialized diagnostic tests and treatment, if necessary;
    3. counselling and education of the patient regarding the nature and scope of needed investigations.
