Overview

Pulmonary nodule may be differentiated according to imaging (size, border characteristics, and attenuation), histological, and clinical features, from other diseases that demonstrate similar imaging findings. Common differential diagnosis of pulmonary nodule, include: hamartoma, granulomas, rheumatoid nodule, and single metastasis.[1][2]

Differential Diagnosis

  • The table below summarizes the findings that differentiate pulmonary nodule from other conditions that cause similar radiological findings on conventional radiograph. é
