Background: Pulmonary cryptococcosis is an uncommon cause of pulmonary nodules found by 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scans. It is rarely reported but may mislead interpretation. Purpose: To describe the 18F-FDG PET/CT findings of pulmonary cryptococcosis. Material and Methods: The 18F-FDG PET/CT images of seven patients with pulmonary cryptococcosis were evaluated. Results: The 18F-FDG PET/CT exams showed single or multiple nodular lesions. The standardized uptake values (SUV) in early images varied significantly for the seven patients (ranging from 2.2 to 11.6). Delayed SUVs showed significant increases in four patients. Conclusion: Pulmonary cryptococcosis mimics primary or metastatic lung cancer on 18F-FDG PET/CT scan. Tissue confirmation should be considered for any suspicious pulmonary nodules found on 18F-FDG PET/CT scan with an SUV score higher than 2.5, in order to avoid overdiagnosis or overstaging.

Background Video-assisted thoracic surgery (VATS) is widely used for thoracic surgery operations, and day by day it becomes routine for the excision of undetermined pulmonary nodules. However, it is sometimes hard to reach millimetric nodules through a VATS incision. Therefore, some additional techniques were developed to reach such nodules little in size and which are settled on a challenging localization. In the literature, coils, hook wires, methylene blue, lipidol, and barium staining, and also ultrasound guidance were described for this aim. Herein we discuss our experience with CT-guided methylene blue labeling of small, deeply located pulmonary nodules just before VATS excision. Method From April 2013 to October 2016, 11 patients with millimetric pulmonary nodules (average 8, 7 mm) were evaluated in our clinic. For all these patients who had strong predisposing factors for malignancy, an 18F-FDG PET-CT scan was also performed. The patients whose nodules were decided to be excised were consulted the radiology clinic. The favorable patients were taken to CT room 2 hours prior to the operation, and CT-guided methylene blue staining were performed under sterile conditions. Results Mean nodule size of 11 patients was 8.7 mm (6, 2–12). Mean distance from the visceral pleural surface was 12.7 mm (4–29.3). Four of the nodules were located on the left (2 upper lobes, 2 lower lobes), and seven of them were on the right (four lower lobes, two upper lobes, one middle lobe). The maximum standardized uptake values (SUV max) on 18F-FDG PET/CT scan ranged between 0 and 2, 79. Conclusion CT-guided methylene blue staining of millimetric deeply located pulmonary nodules is a safe and feasible technique that helps surgeon find these undetermined nodules by VATS technique without any need of digital palpation.

Introduction To determine the incidence of fluorine-18-fluorodeoxyglucose (FDG) avid thyroid incidentalomas detected on positron emission tomography (PET) with integrated computed tomography (CT), and correlate the FDG–PET-CT findings to cytology. Methods A total of 942 FDG–PET-CT reports were retrospectively reviewed. Patients with FDG-avid thyroid incidentalomas were further reviewed for correlative cytology. Results The incidence of FDG-avid thyroid incidentalomas is 2.2%. Thyroid malignancies were identified in 3 of 6 patients who underwent cytologic correlation, with a positive predictive value of 50% (95% confidence interval, 14%-86%). The mean maximum standardized uptake values of benign and malignant FDG-avid thyroid incidentalomas were 5.6 and 6.6, respectively. Conclusion A FDG-avid thyroid incidentaloma may predict underlying malignancy. Cytologic assessment should be considered for FDG-avid thyroid incidentalomas.
