A 35-year-old man in China visited a hospital after experiencing blood in his urine and pain during urination. Medical imaging scans revealed the presence of multiple foreign, needle-like metallic objects in various parts of his body, including his heart, abdomen, pelvis, bladder, and penis. The case was reported in the journal BMC Cardiovascular Disorders. The patient showed no other symptoms or signs of distress when he arrived at the hospital, and his vital signs were stable. A contrast-enhanced scan identified several small metallic items shaped like needles in different areas of his body, including the pericardium, abdominal wall, pelvis, bladder, and penis. An echocardiogram also detected a 36 mm metallic object inside the left ventricle of his heart, which moved in time with the heart wall. The patient, who has a lifelong mental disability, was unable to explain how the needles got into his body. His legal guardian, his father, was also unable to provide an explanation. However, doctors noted that the patient had previously undergone surgery at another hospital two years earlier to remove two foreign objects from his abdomen, suggesting a history of self-insertion, a form of non-suicidal self-injury in which individuals deliberately insert objects into their bodies. Self-insertion can lead to serious complications, including infections, tissue damage, and the migration of objects to other parts of the body. In this case, the needle near the heart posed the greatest risk. Doctors performed open-heart surgery to remove the 36 mm rusted metal needle from the left ventricle. They were surprised to find no entry wounds or scars on the patient's torso that could explain how the object had reached such a critical area. Seven days after the surgery, an echocardiogram showed a small deformation of the left ventricular apex, measuring approximately 3.3 cm, and a blood clot against the heart wall. These complications were attributed to the prolonged presence of the needle and the stress of the surgery. The patient's heart function was assessed at 45% pumping capacity. He was discharged nine days after the surgery and was followed up nine months later. His condition was stable, with no worsening of the heart deformation, and his heart function had improved to 57%.
