case_images: CT and MRI of the patient before surgery. (A) CT plain scan revealed a round, low-density, well-margined bladder lesion (1.9x1.8cm). (B) CT enhanced scan showed moderate round enhancement of the lesion capsule and small flake-enhanced high-density shadows in the lesion parenchyma. MRI showed a cystic lesion (1.9x1.9 cm) with an annular low-signal of the lesion capsule and a small flake-enhanced lesion parenchyma in the transverse (C), coronal (D), and sagittal planes (E). The white arrow in the image indicates the lesion.

case_images: CT plain scan revealed a round, low-density, well-margined bladder lesion (1.9x1.8 cm) ( Figure 1A ). CT enhanced scan showed a moderate round enhancement of the lesion capsule and small flake-enhanced high-density shadows in the lesion parenchyma ( Figure 1B ). MRI with high resolution for soft tissue was recommended. MRI scan showed a cystic lesion (1.9x1.9 cm) with an annular low-signal of the lesion capsule and a small-flake enhanced lesion parenchyma at bladder trigone ( Figures 1C-E ).
case_images: A diagram of the pathology. (A) Pathological morphology of tissue under low magnification. (B) Multilayered squamous epithelium can be seen within the tissue. (C) Fibrous connective tissue can be seen within the tissue. (D, E) Vascular network lacunae can be seen within the tissue. (F) Nerve tissue can be seen within the tissue. (G) Smooth muscle can be seen within the tissue. (H) Chronic inflammatory cells can be seen within the tissue. (I) Bladder mucosa can be seen within the tissue. (J) Bladder mucosa and corpus cavernosum can be seen within the tissue. (K) Smooth muscle under high magnification can be seen within the tissue. (L) Calponin (+). (M) actin (+). (N) SMA (+). (O) Desmin (+). (P) A gross specimen of bladder mass. The white arrows in the image indicate typical pathological sections.

case_images: In addition, chronic inflammatory cells, nerve tissue, and smooth muscle bundles can be seen ( Figure 2 ).
case_images: Ultrasound of the patient 10 months after surgery. (A, B) No significant abnormalities were found in the bladder by ultrasound.
