Leiomyomatosis peritonealis disseminata (LPD) is a rare benign condition characterized by multiple smooth muscle implants in the peritoneal cavity. The clinical presentation is usually nonspecific abdominal discomfort and nontender abdominal mass. Preoperative imaging usually points to suggests malignancy due to its unusual location, but the diagnosis can only be confirmed by histopathological examination. We share F-Fluorodeoxyglucose positron emission tomography-computed tomography images of a 43-year-old woman diagnosed with LPD and briefly discuss the clinical aspects of this disease.

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.

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.

Purpose: To evaluate the prognostic value of interim [F]Fluorodeoxyglucose positron emission tomography/computed tomography ([F]FDG PET/CT) after immunotherapy-based systemic therapies in extranodal natural killer/T-cell lymphoma (ENKTL).
Patients And Methods: We retrospectively recruited 133 newly diagnosed nasal-type ENKTL patients who underwent interim [F]FDG PET/CT scans after 2-4 cycles of immunotherapy-based treatments. Interim PET/CT was interpreted by maximum standardized uptake value (SUV), Deauville 5-point scale (DS), and early treatment response.

Background: Resistance to chemoimmunotherapy in patients with advanced non-small cell lung cancer (NSCLC) necessitates effective prognostic biomarkers. Although F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) has shown potential for efficacy assessment, it has been mainly evaluated in immuno-monotherapy setting, lacking elaborations in the scenarios of immunotherapy combined with chemotherapy. To tackle this dilemma, we aimed to build a non-invasive PET/CT-based model for stratifying tumor heterogeneity and predicting survival in advanced NSCLC patients undergoing chemoimmunotherapy.
