A lung nodule or pulmonary nodule is a relatively small focal density in the lung. A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter. A pulmonary micronodule has a diameter of less than three millimetres. [2] There may also be multiple nodules.
Well-demarcated, nodular lesions ranging 2–5 mm in pulmonary parenchyma. Type II pneumocytes without nuclear atypia lined thickened alveolar septa and proliferated papillary structures. Enlarged cuboidal cells lining mildly thickened alveolar septa. [11] Enlarged cuboidal cells have abundant, eosinophilic cytoplasm and large, round nuclei. [12]
In radiology, the tree-in-bud sign is a finding on a CT scan that indicates some degree of airway obstruction. [1] The tree-in-bud sign is a nonspecific imaging finding that implies impaction within bronchioles, the smallest airway passages in the lung.
Miliary tuberculosis is a form of tuberculosis that is characterized by a wide dissemination into the human body and by the tiny size of the lesions (1–5 mm). Its name comes from a distinctive pattern seen on a chest radiograph of many tiny spots distributed throughout the lung fields with the appearance similar to millet seeds—thus the term "miliary" tuberculosis.

AAH is a pre-malignant cause of nodular GGO and is more commonly associated with lower attenuation on CT and smaller nodule size (<10 mm) compared to adenocarcinoma. [10] In addition, AAH often lacks the solid features and spiculated appearance that are often associated with malignant growths. [ 9 ]
Stevie Mitchell scored 17 points and No. 15 Marquette capitalized on an early 21-0 run to defeat a pesky Central Michigan team 70-62 on Monday night. Kam Jones and Chase Ross each added 12 points ...
A similar study of 40 patients issued in the European Respiratory Journal resulted in an overall 62.5% diagnostic yield and concluded; "electromagnetic navigation bronchoscopy without additional fluoroscopic guidance is a safe and efficient technique for the diagnosis of peripheral pulmonary nodules. The overall diagnostic yield found in the ...
