Many cases are presented incidentally, predominantly in males rather than in females. Purpose: We present cases of patients with an extremely dilated urinary bladder, incidentally found during ultrasonographic examination of the prostate for complaints of incontinence, although they had atypical clinical presentations. Material and Methods: Two patients were examined with ultrasonography, and after that axial computed tomography (CT) was performed. The cases were of a 75-year-old man and a 69-year-old woman. They had experienced a feeling of distention and pain in the abdomen for several years, as well as voiding disturbances—pollakiuria. There were no other clinical pathological findings. Ultrasound examination revealed a multicystic formation with fine sediment in it and dorsal contours. CT and MRI investigations confirmed the findings. The diagnosis was a polycystic retroperitoneal formation with unknown origin. Conclusion: The above-described cases with an extremely dilated urinary bladder are presented in order to draw the attention of diagnosticians because of the relative rarity of such pathologies.
