In recent years the increasing use of sophisticated imaging studies such as magnetic resonance and multidetector computed tomography has resulted in a considerable increase of asymptomatic and unexpected findings. In light of this consideration, the radiologist has more and more frequently the task of correctly interpreting these lesions and give comprehensive information to the patients about their clinical relevance. The purpose of this “special issue” is to describe the most common incidental thoracic and abdominal findings recognized by any imaging technique (X-ray, ultrasound, MDCT, MRI, and interventional radiology procedures) and to provide a useful guide for their interpretation and management.

Researchers and authors should contribute original research as well as review articles that will help to understand incidental thoracic and abdominal findings. We believe that this topic is a very “hot one” in the field of imaging and would deserve attention, so we hope it can be considered suitable for a special issue on BioMed Research International.

Potential topics include but are not limited to the following:

• Incidental pulmonary lesions
• Incidental cardiovascular abnormalities
• Incidental adrenal lesions
• Incidental pancreatic lesions
• Incidental liver lesion
• Incidental renal lesions
• Incidental biliary lesions
• Incidental findings in female pelvis
• Incidental findings in male pelvis
• Incidental nodal and splenic findings
