From: Chest CT examinations in patients presenting with acute chest pain: a pictorial review
A 67-year-old female patient presented with new onset of chest pain and dyspnoea. The patient was diagnosed with an intertrochanteric femur fracture the day before and initial thoracic CT showed no abnormalities. Pulmonary CTA was ordered in order to rule out pulmonary embolism.
