Bladder stones in a closed diverticulum caused by Schistosoma mansoni: A case report

Figure 1 Computed tomography scan images showing two stones at the base of the bladder with a burden of 1. 5 cm. Computed tomography images do not reveal that the stones are present within a diverticulum (orange arrow). A: Axial; B: Sagittal; C: Coronal images.

Figure 2 Hematoxylin and eosin staining images of resected diverticulum at 200× magnification. Lamina propria show multiple granulomatous inflammation around calcified ova. Marked fibrosis and chronic inflammation were also observed surrounding the calcified ova.

Figure 3 Hematoxylin and eosin staining images of resected diverticulum at 400× magnification. The image shows that the majority of the Schistosoma eggs are calcified with some showing lateral spines.
