case_images: CT scan acquired in arterial phase, after intravenous administration of iodinated contrast media. This image shows a highly vascular lesion within the right wall of the bladder dome (yellow arrow). Some small feeding arteries are appreciable too. The bladder is empty due to urinary catheterization via Foley catheter.

case_images: The patient was therefore admitted to the urology department of our hospital and a CT Urography was performed, demonstrating a significantly contrast-enhanced bladder nodule fed by thin arterial vessels originating from both left and right hypogastric arteries (Figure 1).
case_images: MRI angiography, axial LAVA sequence acquired in arterial phase after administration of intravenous contrast media, with Maximum Intensity Projection reformatting. This image depicts the highly vascularized lesion and its feeding vessels (blue arrow).

case_images: The patient subsequently underwent MRI angiography, that clearly depicted the lesion and its multiple afferent feeding arteries, confirming the findings described on CT-scan (Figure 2).
case_images: FDG PET/CT (image fusion technique) acquired in an early phase, 3 min after administration of the 18FDG. The image shows intense uptake of the 18FDG by the tumor (white arrow). The smaller high uptake spot on the left corresponds to physiological collection of urine within the ureter (purple arrow).

case_images: In particular, FDG PET showed an early intense FDG uptake with a complete washout after 60 min (Figures 3, 4).
case_images: FDG PET/CT (image fusion technique) acquired in a late phase, 60 min after administration of the 18FDG. The bladder lesion is characterized by complete washout of the 18FDG, that collects in the urine, within the bladder (white arrow).
