Pleuropulmonary blastoma (PPB) is a rare invasive primary malignancy in the thoracic cavity that occurs mainly in infants and children. It is often misdiagnosed and not treated correctly and promptly due to the lack of specificity of clinical symptoms and conventional imaging presentations. We report a 2.5-year-old boy who underwent X-ray chest radiography, chest CT, and F-FDG PET/CT. PET/CT images demonstrated a sizeable cystic-solid mass with heterogeneous increased glucose metabolism in the left thoracic cavity. The diagnosis of PPB (type II) was finally confirmed by a CT-guided puncture biopsy of the active tumor tissue. This case highlights the critical role of F-FDG PET/CT in the diagnosis of PPB in children.

A 61-year-old male presented with hematemesis and melena. Biopsy and immunohistochemistry confirmed mucosa-associated lymphoid tissue (MALT) lymphoma in the posterior wall of the gastric antrum, prompting further evaluation with F-fluorodeoxyglucose (F-FDG) positron emission tomography/computed tomography (PET/CT). In addition to elevated uptake in the gastric antrum, F-FDG PET/CT showed diffuse uptake in multiple bone marrow, initially suspected to indicate bone marrow involvement by lymphoma.

Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a type of skin T-cell lymphoma with a favorable prognosis. Some patients may experience recurrence, but systemic involvement is rare. Some studies suggest that systemic progression is associated with poor prognosis.

Background And Objectives: This study aims to evaluate the correlation between Tumor-Infiltrating Lymphocyte (TIL) levels and Fluorine-18 fluorodeoxyglucose (F-FDG) metabolic parameters, including spleen and bone marrow FDG uptake and tumor heterogeneity in non-luminal breast cancers (NLBC), and to elucidate their association with survival outcomes.
Methods: We retrospectively analyzed data from 100 females with stage 2-4 NLBC who underwent pretreatment F-FDG Positron emission tomography-computed tomography (PET/CT). TIL was scored based on Hematoxylin-Eosin-stained specimens and F-FDG PET metabolic parameters, including maximum standardized uptake value (SUVmax), mean standardized uptake value (SUVmean), metabolic tumor volume (MTV), total lesion glycolysis (TLG), liver, spleen, and bone marrow FDG uptake were calculated.

Background: Radiomics features extracted from baseline F-fluorodeoxyglucose positron emission tomography (F-FDG PET) scans have shown promising results in predicting the treatment response and outcome of diffuse large B-cell lymphoma (DLBCL) patients. This study aimed to assess the influence of lesion selection approaches and segmentation methods on the radiomics of DLBCL in terms of treatment response and prognosis prediction.
Methods: A total of 522 and 382 patients pathologically diagnosed with DLBCL were enrolled for complete regression and 2-year event-free survival prediction, respectively.

Objectives: To assess the prognostic value of Fluorine 18-labeled fluorodeoxyglucose [F]FDG, gallium 68-labeled fibroblast-activation protein inhibitor-04 [Ga]Ga-FAPI-04, C-acetate in hepatocellular carcinoma (HCC) and evaluate the potential usefulness and advantages of different combinations for accurate diagnosis.
Materials And Methods: Thirty-six patients with suspected hepatic masses were prospectively enrolled from May 2021 to September 2022 and underwent [F]FDG, [Ga]Ga-FAPI-04, and C-acetate PET/CT scans before surgery. PET/CT results and histopathologic examinations were independently interpreted by two radiologists and pathologists, respectively.
