Abstract
Pulmonary embolism (PE) is a common, potentially fatal condition that clinicians have difficulty in diagnosis. Diagnosis should be made by combination of symptoms, signs, scintigraphic and radiological features. Here we report a case of diaphragmatic paralysis who was admitted with dyspnea, chest pain and was investigated for PE. In this report we reviewed the difficulties of clinical and radiological features of PE and their importance in the differential diagnosis of PE.
