F-18 Fluorodeoxyglucose Positron Emission Tomography in Pulmonary Cryptococcoma

Abstract: Cryptococcosis is not uncommon. Potential interpretation pitfalls should be kept in mind when fluorodeoxyglucose (FDG) positron emission tomography (PET) is used for differentiating pulmonary nodules and for discriminating infection from malignancy, especially in areas where the prevalence of granulomatous infection is high and in immunocompromised patients. In this case, a nodular mass was shown on chest radiography and computed tomographic (CT) scanning. A consolidated infection or a bronchioloalveolar carci… Show more

“…Previous reports have suggested intermediate increased 18 F-FDG uptake in fungal infections [4]. However, we encountered two cases of fungal infections (aspergillosis and coccidioidomycosis, respectively) that showed intense 18 F-FDG uptake, thereby mimicking lung cancer (Fig.…”

“…However, the natural course of the disease on imaging studies, particularly how quickly the lung lesions evolve before adequate treatment of the disease and how the lung lesions show response to surgical or antifungal therapy, has not been well documented. Only a few reports document the PET findings of pulmonary cryptococcosis (14-17). Thus, the purpose of our study was to review patterns of lung abnormalities of pulmonary cryptococcosis on CT images, assess the PET findings of the disease, and evaluate the response of lung abnormalities to the different therapies.…”

“…FDG accumulates in macrophages and young granulation tissue caused by pulmonary cryptococcosis [10]. There have been few reports of FDG-PET analysis of pulmonary cryptococcosis, except for one case report by Hsu et al [4]. In the present series, FDG-PET showed accumulation of FDG in all four cases that were examined by this modality, and these cases were difficult to distinguish from lung cancer.…”
