We report the case of a 9-year-old girl who presented with acute fevers, cough, and epistaxis with nasal swelling, and found to have a nasal mass. On F-FDG PET/CT, she was found to have marked nodal and pulmonary parenchymal disease with diffuse and symmetrical mural FDG uptake within the trachea and bronchial tree. The differential diagnosis was broad, and she was diagnosed with IgG4-RD (IgG4-related disease) and improved on appropriate treatment. To our knowledge, there are only 2 other pediatric cases of IgG4-related pulmonary disease in the literature, and our case serves as a unique constellation of intrapulmonary IgG4-RD imaging findings.

Primary pulmonary artery sarcoma is an extremely rare and highly aggressive malignant tumor of cardiovascular system. It is usually misdiagnosed as pulmonary thromboembolism due to its atypical clinical features and similar clinical symptoms. Different from published reports, our case received both enhanced CT and 18F-FDG PET/CT examination before the pathologic result, and lung metastases had already occurred at the time of diagnosis. we herein reported a case of 41-year-old female patient who suffered from cough and chest tightness for more than a month. Laboratory examination indicated that both blood routine and tumor markers were within the normal range, and only the D-dimer slightly elevated. contrast-enhanced chest computed tomography showed right pulmonary artery lesion and multiple nodular located right upper lung, the lesion was mild heterogeneous enhancement. no obvious abnormalities were found in deep vein of bilateral lower extremities on ultrasonography. In order to confirm the nature of these lesions, PET/CT scan was performed, which revealed stripe hypermetabolism in right pulmonary artery and nodular hypermetabolism in right upper lung, and the rest of the whole-body PET imaging were negative, a diagnosis of primary pulmonary artery malignancy with pulmonary metastases was made, and pulmonary thromboembolism was ruled out. biopsy of right pulmonary lesions was performed and histopathological examination indicated pulmonary artery sarcoma. She only received palliative conservative medical treatment because the disease was late stage according to the tumor-node-metastasis (TNM) staging system, and did not acceptable surgical treatment, and was in good health during recent follow-up. Our study suggested that 18F-FDG PET/CT image is a good approach for the diagnosis of pulmonary artery sarcoma and could provide adjunct value for further treatment.

A 71-year-old man was referred to pulmonary clinic for incidental findings of hypermetabolic lung nodule and mediastinal adenopathy on CT FDG PET performed for evaluation of cough. The patient underwent bronchoscopy with endobronchial ultrasound that was non-diagnostic. The patient was subsequently sent for video-assisted thoracoscopic lymph node biopsy notable for confluent caseating granulomas due to chronic infection by Histoplasma capsulatum Review of previous PDG PET was notable for the flip flop fungus sign-a PDG PET finding that could have altered the patients' clinical course by potentially avoiding the need for invasive surgical tissue diagnosis.
