(a) Coronal reformatted CT image (window level 50, window width 350), showing an enhancing soft tissue mass at the intervertebral foramen (arrow), causing erosion of the adjacent portion of the lamina (curved arrow).  |  Base the risk assessment of people with multiple pulmonary nodules on that of the largest nodule.

Fig. 2b. To be considered solitary, a nodule must be completely surrounded by normal lung parenchyma, without associated atelectasis, enlargement of the hilum, or pleural effusion. Approximately 50% of the nodules calcify or ossify (1,5). Other less commonly encountered diseases that present as multiple pulmonary nodules include infections, arteriovenous malformations, Wegener's granulomatosis, and lymphoma. There was no family history of cancer. Solitary Pulmonary Nodule Differential Diagnosis: Benign SPN • Non-specific or healed granulomas (25%) • Infectious granulomas (15%) • Benign neoplasms (15%) ‒ Hamartoma ‒ Lipoma, fibroma, countless others (rare) • Others: lung abscess, pseudotumor, round atelectasis, AVM, infarct, mucoid impaction, hematoma, rheumatoid nodule, Wegenerʼs. (a) Axial CT image, lung window (window level −500, window width 1500) shows multiple discrete pulmonary nodules (arrowheads). Pulmonary function tests were within normal ranges. HHS Lung nodules may be solitary or multiple. [ncbi.nlm.nih.gov] Show info. Background Multiple pulmonary nodules is a finding that is often difficult to interpret, challeging even for experienced professionals. Multiple pulmonary nodules (arrowheads) are seen in the right middle lobe, lingula and left lower lobe. Published in: 2018 IEEE International Conference on Bioinformatics and Biomedicine (BIBM) Rev Inst Med Trop Sao Paulo. Although uncommon, in specific patient groups, pulmonary ossifications should also be considered. A 39-year-old nulligravida indian female patient with type I diabetes mellitus and skin manifestations. However, the diagnosis may be aided by recognizing extrapulmonary lesions that are often associated with lung diseases. A 19-year-old woman with progressive dyspnea and multiple pulmonary nodules. Keywords: Mitral Valve Stenosis, Multiple Pulmonary Nodules, Idiopathic pulmonary hemosiderosis. Both the CT and FDG PET characteristics, as well as the clinical scenarios, should be considered when characterizing multiple pulmonary nodules. Atypical Pulmonary Metastases: Spectrum of Radiologic Findings. Nodule malignancy risk prediction models should be validated in patients with known extrapulmonary cancer. Radiologically, the primary nodular parenchymal pulmonary amyloidosis appear as single or multiple nodules in any lobe, and should be considered in the differential diagnosis of pulmonary primary or metastatic neoplasms. the Academical Medical Centre, Amsterdam and the Alrijne Hospital, Leiderdorp, the Netherlands. The differential diagnosis of a solitary pulmonary nodule is broad and management depends on whether the lesion is benign or malignant. They can arise from a vast number of pathological entities. According to the current international guidelines, size and growth rate represent the main indicators to determine the nature of a pulmonary nodule. A case mimicking radiological features of pulmonary metastasis.
