Background Renal arteriovenous malformations (rAVMs) are congenital abnormal pathways between renal arteries and veins that rare in the general population. It is often misdiagnosed as malignant tumors with abundant blood supply, definitive diagnosis primarily relies on angiography. Multimodality imaging, including contrast-enhanced computed tomography (CT), magnetic resonance imaging (MRI), positron emission (PET)/CT plays an important role differential of space-occupying lesions. Case presentation A 56-year-old man presented abdominal distension, loss appetite, back pain without obvious cause 2 years ago, nausea vomiting, or frequent urination. Gastroscopy colonoscopy showed multiple polyps duodenum colon. Abdomen CT revealed a mass 1.6 × 1.4 cm left kidney, which was considered to be tumor. PET/CT performed for further diagnosis; 18 F-fluorodesoxyglucose ( F-FDG) scan mild uptake mass, while no F- prostate-specific membrane antigen (PSMA) observed. Following multidisciplinary discussion, possibility AVMs subsequently confirmed by angiography diagnosis. Then, selective segmental artery embolization treatment. Conclusion extremely clinical practice. Due limited research application F-FDG F-PSMA AVMs, its remains largely unexplored. With increasing popularity comprehensive disease has become indispensable. We report first case PSMA when expression absent should considered.

Background: Stereotactic body radiation therapy (SBRT) is the most commonly used metastasis-directed (MDT) for oligometastatic urothelial carcinoma (omUC). Despite efforts in defining this disease entity, open questions remain concerning role of MDT and use biomarkers, imaging, its combination with systemic therapies. The aim present systematic review to provide an updated overview current clinical evidence on SBRT omUC terms survival local control benefits. We also updates controversial areas future directions emerging field. Methods: With a approach, following PRISMA recommendations, we searched two databases identify select articles published up until March 2024 reporting or without concomitant Prospective randomized non-randomized studies as well retrospective were included. Results: Eight selected data extraction 293 patients treated collectively analyzed. In metachronous patients, delivered ablative doses (BED10 ≥ 78 Gy) was associated 2-year overall (OS) rate 50.7% (95% CI 35.1–64.4%). sub-ablative = 43.2 immunotherapy did not demonstrate significant outcome improvement prospective studies. tolerance good, only one study toxicity grade 3 18% immunotherapy. Conclusions: effective widely available option omUC, although based limited number attempt immune response trigger immunotherapy, no outcomes has been observed. integration new agents will likely define scenario treatment omUC. protocol registered PROSPERO, ID: CRD42024522381.
