He reportedly wasn’t experiencing chest pain or difficulty breathing. Yet imaging revealed an unusual shadow near his heart, prompting doctors to investigate further.
What they found was extraordinary.
Doctors Discover Metal Objects Throughout His Body
A contrast-enhanced CT scan revealed several “needle-like metallic foreign bodies” in different areas of the man’s body.
The objects weren’t confined to one location.
Doctors found them in his abdominal wall and pelvis, as well as his bladder and penis.
But one object posed a far more immediate threat.
A sewing needle measuring approximately 1.4 inches had penetrated the sac surrounding the man’s heart and become lodged in the wall of his left ventricle.
The left ventricle performs the crucial job of pumping oxygenated blood from the heart into the body’s circulation.
Doctors determined that leaving the needle there presented a potentially serious danger.
Even stranger, there was apparently no obvious evidence showing how it had entered his chest.
No Visible Chest Wound Offered an Answer
According to the medical report, the patient has lived with an intellectual disability since childhood and was unable to explain how the foreign objects ended up inside him.
His father, who serves as his legal caregiver, reportedly couldn’t provide an explanation either.
However, doctors discovered an important detail in the man’s medical history.
Two years earlier, another hospital had removed two foreign objects from his abdomen.
That history led the medical team to suspect self-embedding — an uncommon form of self-injury involving the insertion of objects into the body.
Yet the needle near his heart remained especially puzzling.
Doctors could not identify an obvious entry wound or scar on his chest that explained how the object had traveled there.
When surgeons eventually removed it, they found that the needle had turned black from corrosion, indicating it had likely been inside his body for a considerable amount of time.
The case demonstrates just how difficult foreign-body injuries can be to identify when patients cannot clearly communicate what happened.
The Chinese medical team warned that among patients with cognitive impairments, such cases “can be clinically occult, requiring a high index of clinical suspicion.”
In other words, something extremely dangerous may be developing without producing the symptoms doctors would normally expect.
Surgeons Open His Chest to Remove the Needle
Because of the danger posed to his heart, doctors decided that the cardiac needle had to come out.
Surgeons opened the patient’s chest through his sternum.
Using transesophageal echocardiography — an ultrasound technique involving a probe inserted into the esophagus to obtain detailed images of the heart — they located the foreign object and successfully removed it intact from the ventricular wall.
But the operation wasn’t the end of the medical ordeal.
Within approximately one week, doctors found that the man’s heart function had deteriorated.
His left ventricular ejection fraction, a measurement used to evaluate how effectively the heart pumps blood, had fallen to 45 percent.
Doctors also observed a bulge near the tip of the left ventricle and suspected that a blood clot had developed along the heart wall.
Despite those complications, the patient was discharged nine days after surgery.
His longer-term recovery was more encouraging.
At a nine-month follow-up, doctors reported that his heart function had improved, with his ejection fraction reaching 57 percent. His condition was described as stable.
Other Foreign Objects Remain Inside His Body
Perhaps the most unsettling part of the case is that surgeons did not remove every foreign object.
The objects discovered around the man’s pelvis, bladder and penis remain inside his body.
Doctors apparently concluded that attempting to extract them could create greater medical risks than carefully monitoring them.
The patient will therefore require continued observation.
Although this particular case is highly unusual, self-embedding behavior has previously appeared in medical literature in the United States.
Similar Cases Were Documented in Ohio
In 2011, researchers associated with Nationwide Children’s Hospital in Columbus, Ohio, reported a series of self-embedding cases involving young patients.
Over a three-year period, radiologists identified 11 patients displaying the behavior. According to the report published in Pediatrics, every patient in the group had received a psychiatric diagnosis.
Doctors encountered an assortment of embedded objects, including metal, glass, wood and even pieces of crayon.
Many were discovered in areas such as the arms, wrists, ankles and lower legs.
Dr. William Shiels, who led the research, urged medical professionals to “rapidly pursue targeted intervention to interrupt the cycle of self-harm.”
Those cases largely involved objects positioned relatively close to the skin.
The Chinese patient’s case was dramatically different.
One foreign object had reached the wall of one of the heart’s most important chambers without causing the kind of obvious cardiac symptoms that might have immediately alerted doctors.
Instead, the discovery began because the patient complained about painful urination.
His previous history of unexplained foreign objects ultimately provided doctors with another clue about what they might be dealing with.
The bizarre case underscores a potentially serious challenge for physicians and caregivers: When a vulnerable patient cannot reliably explain an injury, the absence of obvious symptoms does not necessarily mean the absence of danger.
For this patient, an investigation that began with urinary symptoms ended with surgeons removing a corroded sewing needle from his heart — while doctors continue watching the other foreign objects still inside his body.
