Introduction:
Pulmonary embolism (PE) is associated with many etiologies, such as hematological disorders, contraceptive use, tumors, trauma, infection, and dehydration.1 However, iron deficiency anemia (IDA) is a very rare etiology of PE.1 IDA leads to relative thrombocytosis, causing hypercoagulation and venous thromboembolism.2 This is a case study of a 29-year-old female who presented with shortness of breath and left-sided pleuritic chest pain. The diagnosis of a PE most likely due to IDA was established based on CT angiogram (CTA) of the chest and blood findings and ruling out other differential diagnoses related to PE.
