Abstract Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm with a low incidence, and pelvic SFT is extremely uncommon. Due to its insidious onset and nonspecific imaging features, preoperative diagnosis is difficult. We reported a 34-year-old male patient with a giant pelvic SFT found incidentally during physical examination, complicated with left hydronephrosis and hydroureter. Preoperative imaging revealed a large heterogeneous enhanced mass in the pelvic cavity.

Abstract Click to copy section linkSection link copied! China needs rapid electricity system decarbonization to achieve climate goals, yet planning still relies on annual average grid emission factors (GEFs) that ignore time variation. In this study, we construct monthly electricity networks in China from January 2019 to December 2023 using operational grid data and then apply a multiseasonal structural decomposition of emission changes to quantify driver contributions.
