Which of the following is not a listed differential diagnosis for chest pain?

• A. Pulmonary Embolism, Aortic Dissection, Arrhythmia
• B. Migraine
• C. Pneumonitis
• D. Stress fracture

Answer: (B)

In chest pain assessment, clinicians focus on causes from the heart and lungs, the chest wall, and other thoracic structures, paying attention to red flags that point to life-threatening problems. The listed causes—pulmonary embolism, aortic dissection, and arrhythmia—are classic cardiopulmonary or vascular sources of chest pain that can threaten stability and require urgent evaluation. Pneumonitis is a lung inflammatory issue that can produce pleuritic or chest wall pain, and a stress fracture can cause localized, reproducible chest pain from the rib or sternum area.

Migraine, on the other hand, is a primary headache disorder. It typically presents with head pain and associated symptoms such as nausea, photophobia, or phonophobia, rather than chest wall or cardiopulmonary pathology. While headaches can occur with chest symptoms in rare cases, it is not a standard chest-pain differential diagnosis. Therefore, migraine is not considered a listed differential for chest pain.
