Background: The evaluation of solitary lung nodules via FDG PET/CT has high sensitivity for nodules larger than 8 mm and is utilized to exclude lung cancer. Aim: This study aimed to retrospectively explore whether the lesions in patients who underwent F18 fluorodeoxyglucose-positron emission tomography/computed tomography imaging with the staging of the solitary pulmonary nodule and lung mass were within the local imaging area. It also investigated whether a relationship existed between the size of the lung lesion and extrathoracic spread. Materials and Method: Three hundred eight patients histopathologically diagnosed lung cancer were included in this study. All patients lung lesions were measured and patients were classified as four groups according to the size of the lung lesion. In all groups, the F18 FDG PET/CT examination was used to detect liver, adrenal, bone and supraclavicular lymph node metastasis, besides extrathoracic metastasis. Results: Liver, bone and extrathoracic metastasis of group-1 was statistically lower than group-2 (P < 0.001, p<0.01 and P = 0.03, respectively). Liver, extrathoracic, adrenal and bone metastasis of group-3 was statistically lower than the group-4 (P<0.001, P = 0.01, and P = 0.04, p<0.01 respectively). Extrathoracic extension was observed in only one patient in the group-3. In addition liver, adrenal, and bone metastases were not observed in any group-3 patients. Conclusions: PET/CT may be a more appropriate approach to be aplied in cases with nodule diameter ≤20mm. Performing local imaging in patients with a nodule diameter of ≤20 mm could not only reduce radiation exposure but also save radiopharmaceuticals used in PET/CT imaging.

Pulmonary Langerhans cell histiocytosis (PLCH) is a rare inflammatory condition that mostly affects lungs in smokers. On imaging, it usually presents as multiple, upper lobe predominant, solid, and cavitary nodules, but presentation as solitary pulmonary nodule (SPN) is rare. We describe a case of SPN seen on low-dose lung cancer screening CT (LDCT) that was FDG avid on PET/CT. Given concern for malignancy, lobectomy was planned if intraoperative frozen section was consistent with malignancy. Lobectomy was performed based on frozen section; however, on formal pathology review, the nodule was ultimately found to be PLCH. This case illustrates an atypical presentation of PLCH as a solitary nodule. Furthermore, it helps demonstrate how rare etiologies (like PLCH) may be more frequently encountered and should be considered in the differential diagnosis for solitary lung nodules, especially in the era of lung cancer screening.

Material and methods: Since 2014, 33 patients with lung cancer of clinical stage I-IIa (cT1N0M0 - 12 patients, with T2N0M0 - 21 patients) have undergone SRT. Verification of tumor process was obtained in 30 patients. A third of patients (n = 10) had a history of metachronic primary-multiple tumors and 31 patients had peripheral lung cancer. The used variants of SRT fractionation were as followed: 10Gr x 5 fractions (n = 22) and 7Gr x 8 fractions (n = 11) - BED 100Gy. Results: With a median follow-up of 21 months (range 3-37 months), 4 patients (12 %) within the first year had a loco-regional and distant progression, of which two died. During the year one patient died from complications of treatment, one - from the progression of the second tumor. One- and two-year local control was 94 %. Overall and disease-free 2-year survival was 84 % (95 % CI, 70 - 99) and 83.2 % (95 % CI, 70.5 - 99), respectively. Single-factor analysis revealed a significant effect on the overall survival of the fractionation regimen (p = 0.04). The effect of the baseline SUVmax tended to be reliable (p = 0.07). Conclusions: In order to implement the principles of risk-adaptive radiation therapy it is necessary to consider the initial SUVmax of tumor as one of potential predictive and predicative markers of treatment effectiveness.

Abstract Background Solitary pulmonary nodules are the most common incidental finding on chest imaging. Their management is very well defined by several guidelines, with risk calculators for lung cancer being the gold standard. Solitary intramuscular metastasis combined with a solitary pulmonary nodule from malignant melanoma without a primary site is rare. Case presentation A 57-year-old white male was referred to our lung cancer service with solitary pulmonary nodule. After positron-emission tomography, we performed an ultrasound-guided core needle biopsy of an intramuscular solitary lesion, not identified on computed tomography scan, and diagnosed metastatic malignant melanoma. The solitary pulmonary nodule was resected and also confirmed metastatic melanoma. There was no primary skin lesion. The patient received oral targeted therapy and is disease-free 5 years later. Conclusions Clinicians dealing with solitary pulmonary nodules must remain vigilant for other extrathoracic malignancies even in the absence of obvious past history. Lung metastasectomy may have a role in metastatic malignant melanoma with unknown primary.
