A 55-year-old woman in Chengdu, China, had been passing blood in her urine on and off for six months without pain and had never had it looked at. Two days before she finally came in, straining brought on heavy bleeding along with urinary frequency and urgency. An ultrasound found the back wall of her bladder irregularly thickened over an area measuring about 5.3 by 1.9 by 5.5 centimeters, with dense blood flow signals running through it. The reading pointed toward a malignant tumor.
It was a fish bone. Roughly 3 centimeters of it, lodged at the pelvic floor with one end in the rectal wall, the other pushed through the bladder muscle, and one side embedded in the outer layer of the uterus. The case report was published in Frontiers in Oncology.
