Abstract Background: In high COVID-19 prevalence region, COVID-19 disease may be incidental found in non-specific symptoms or asymptomatic patient with history of tumor who underwent 18F-FDG-PET/CT for standard oncologic indications.Case presentation: A 51-year-old woman with a 4-year history of adenoid cystic carcinoma of nasal cavity underwent 18F-FDG PET/CT for restaging during COVID-19 outbreak in Wuhan. Pneumonia lesions were characterized by 18F-FDG uptake ground-glass opacities (GGOs) and multifocal high 18F-FDG-avid patchy consolidation, and without lymph node involvement and pleural effusion. Furthermore, multiple 18F-FDG-positive lung and lumbar metastases were observed. Finally, a diagnosis of COVID-19 was made based on a positive real-time fluorescent polymerase chain reaction (RT-PCR) test of SARS-CoV-2 nucleic acid. Conclusion: The non-specific symptoms or asymptomatic cancer patients presenting 18F-FDG-positive GGOs and patchy consolidation lesions in lung may favor COVID-19, who should be quickly SARS-CoV-2 nucleic acid tested and monitored.

Eosinophilic fasciitis is a rare connective tissue disease with a clinical presentation of scleroderma-like disease. We report a case of a 36-year-old female patient with a 6-month history of progressive stiffness involving her forearms and legs with joint pain. Laboratory examinations showed hypereosinophilia and elevated C-reactive protein. 18F FDG PET/CT showed diffuse and symmetrical increased uptake in the fasciae of the upper and lower limbs, sparing both muscles and fat tissues. Guided biopsy and histologic examination confirmed the diagnosis of eosinophilic fasciitis. 18F FDG PET/CT is of great help in the diagnosis of eosinophilic fasciitis, as it can guide the biopsy where FDG uptake is strongest and also help rule out possible associated neoplasms.

Abstract Background The vaccination immune response may induced false-positive 18F-FDG PET/CT uptake.Case presentationAn extended supraclavicular lymph nodal activation after Coronavirus Disease 2019 (Covid-19) vaccination revealed on 18F-FDG PET/CT mimics a Virchow nodule in a patient with medical history of well-differentiated appendicular adenocarcinoma. Conclusion This case highlights a nodal activation beyond axillary area and the importance of documenting vaccination history at the time of scanning to avoid false-positive results.

AbstractWe conducted a systematic literature review on the use of [18F]FDG PET/MRI for staging/restaging rectal cancer patients with PubMed, Scopus, and Web of Science, based on the PRISMA criteria. Three authors screened all titles and abstracts and examined the full texts of all the identified relevant articles. Studies containing aggregated or duplicated data, review articles, case reports, editorials, and letters were excluded. Ten reports met the inclusion criteria. Four studies examined T staging and one focused on local recurrences after surgery; the reported sensitivity (94–100%), specificity (73–94%), and accuracy (92–100%) varied only slightly from one study to another. The sensitivity, specificity, and accuracy of [18F]FDG PET/MRI for N staging were 90–93%, 92–94%, and 42–92%. [18F]FDG PET/MRI detected malignant nodes better than MRI, resulting in treatment change. For M staging, [18F]FDG PET/MRI outperformed [18F]FDG PET/CT and CT in detecting liver metastases, whereas it performed worse for lung metastases. The results of this review suggest that [18F]FDG PET/MRI should be used for rectal cancer restaging after chemoradiotherapy and to select patients for rectum-sparing approaches thanks to its accuracy in T and N staging. For M staging, it should be associated at least with a chest CT scan to rule out lung metastases.
