, sharply defined lung lesion seen on a chest x-ray. Causes, incidence, and risk factors Return to top About 60% of all solitary pulmonary nodules are benign (not cancerous). Benign nodules have many causes, including old scars and infections. Infectious granulomas (inflammations of granular tissue) are the cause of most benign lesions. When a nodule is malignant, lung cancer is the most common cause. Exposure to tuberculosis or an infectious fungus (histoplasmosis, coccidioidomycosis) can increase the risk of developing a solitary pulmonary nodule, but also makes it more likely that the nodule is benign. Young age, absence of tobacco exposure, calcium in the lesion, and small lesion size are factors favoring a benign diagnosis. About 150,000 new solitary pulmonary nodules are diagnosed each year in the United States. Of these, 45,000 require no further testing besides a careful history and review of an old chest x-ray, if available. Symptoms Return to top There are usually no symptoms. Signs and tests Return to top A solitary pulmonary nodule is usually found on a chest x-ray. If serial chest x-rays (repeated x-rays over time) show the nodule size unchanged for 2 years, it is considered benign. A chest CT scan is often performed to evaluate a solitary pulmonary nodule in detail. Other tests may include the following: PET scan Single-photon emission CT (SPECT) Skin tests to rule out infectious causes Percutaneous needle biopsy Surgical lung biopsy Treatment Return to top Most nodules in patients over 35 years old should be considered potentially malignant until proven other pulmonary nodules

pulmonary nodules needed to establish whether the lesion is benign or malignant. This chapter gives an approach for estimating malignancy versus benignity. The evaluation of a solitary pulmonary nodule should be systematic and appropriate for the individual patient. There is an increasing frequency of malignancy occurring in lesions with irregular edges pulmonary nodules, without calcification pulmonary nodules, occurring in patients over the age of 50 years pulmonary nodules, whose lesions double within a 2 year period. The decision for operative removal versus electing a period of observation of the nodule can be made based on nodule characteristics pulmonary nodules, patient age and rate of growth of the lesion.

pulmonary nodules Er manifesting as SPN may be the only chance for cure.Pathophysiology: An SPN is defined as a single, discrete pulmonary opacity that is less than 3 cm in diameter, surrounded by normal lung tissue, and not associated with adenopathy or atelectasis. Generally, a pulmonary nodule must reach 1 cm in diameter before it can be identified on a chest radiograph. For a malignant nodule to reach this size, approximately 30 doublings would have occurred. The average doubling time for a tumor is 120 days (range, 7-590 d). A lesion at this growth rate may be present for 10 years before discovery. An SPN may be secondary to one of the numerous differential diagnoses listed in Causes. However, more than 95% are neoplasms (most likely primary), granulomas (most likely infectious), or benign lesions (most likely hamartoma).Frequency: In the US: SPNs are one of the most common thoracic radiographic abnormalities. Approximately 150,000 cases are detected each year as an incidental finding, either on im
