Surgeons in Los Angeles expected to remove a massive 22-pound growth from a pregnant woman’s abdomen. Instead, they uncovered a nearly full-term baby boy tucked behind the tumor, alive and waiting to be delivered. The discovery turned a high-risk operation into what the medical team and family now openly describe as a miracle of modern obstetrics and human resilience.
The mother, Suze Lopez, had gone into surgery believing she was treating a dangerous mass that threatened her health and her pregnancy. By the time doctors finished, they had not only removed the tumor but also safely delivered her son, whose survival outside the uterus defied both anatomy and the odds.
The hidden baby behind a 22-pound tumor
For months, Suze Lopez had been told that the rapidly expanding size of her abdomen was the result of a large tumor, and she prepared for surgery with the understanding that the growth could be life-threatening. Before the operation, she took a routine pregnancy test that confirmed she was expecting, but even then, specialists believed the baby was developing inside the uterus while the 22-pound mass crowded her organs and fueled her pain. Only once surgeons opened her abdomen did they realize that what they had taken for a single problem was actually two extraordinary and intertwined conditions, a massive tumor and a baby growing in a place no one anticipated, as later detailed in accounts of how doctors removed the 22-pound tumor.
What the team ultimately found was a rare abdominal ectopic pregnancy, in which the embryo had implanted outside the uterus and continued to grow almost to term. Surgeons described locating the baby in a tight pocket of the abdomen near the liver, with his body pressed up against the surrounding structures and his position obscured by the tumor’s bulk. The baby, later identified as Ryu Lopez, had developed outside of his mother’s uterus behind the enormous cyst, a scenario so unusual that many obstetricians will never see a comparable case in their careers, according to reports on how Ryu Lopez developed outside the uterus.
A marathon surgery and a “medical miracle”
Once the surgical team understood that they were dealing with both a giant tumor and a nearly full-term abdominal ectopic pregnancy, the stakes shifted from complex to historic. Specialists from multiple disciplines assembled in the operating room in Los Angeles, coordinating each step to protect both mother and child while navigating distorted anatomy and fragile blood vessels. The hospital later explained that it took a team of experts to remove the tumor and deliver the baby safely despite serious complications, describing the coordinated effort in a detailed account of the team’s work.
The operation itself lasted about 3.5 hours, a span in which surgeons had to control bleeding, separate the 22-pound mass from surrounding organs, and then perform a delicate delivery in an area never meant to hold a pregnancy. After the surgery, everything went well for both mom and baby, with Suze Lopez’s blood loss and recovery tracking close to what doctors would expect after a standard cesarean section, according to clinical descriptions that noted the 3.5 hour surgery and its outcome.
Why this case stunned even veteran doctors
Abdominal ectopic pregnancies are rare to begin with, and they almost never progress to a point where a baby can be delivered alive. In this case, the fetus had grown to nearly full term in a space behind a tumor so large that it masked his presence on imaging and physical exams. At Cedars, Sinai Hospital in Los Angeles, where the operation took place, clinicians later described the sequence of discoveries and decisions in a news release that underscored how unusual it was to find a viable baby in that setting, with the institution in Los Angeles recounting the events.
The story quickly drew global attention, in part because it combined a worst-case obstetric emergency with an unexpectedly joyful outcome. Commentators highlighted how close Suze Lopez and her son came to tragedy, and how the surgical team’s preparation and split-second decisions turned what might have been a fatal complication into a living child. Coverage captured the sense of awe among clinicians, with one report summarizing how Doctors Stunned by Medical Miracle, Ectopic Baby Hidden Behind Pound Tumor Mom reflected the disbelief that such a pregnancy could progress so far without catastrophe.
A mother’s shock, a baby’s fragile start, and a wider warning
For Suze Lopez, the emotional whiplash was as intense as the medical drama. She had entered the hospital bracing for the removal of a tumor that threatened her life and her fertility, only to learn that she was carrying a baby in a place no one expected. Reports describe how she first discovered she was pregnant shortly before the operation, then woke up to the news that her son had been delivered in the middle of the tumor surgery, a sequence captured in coverage of how Doctors delivered the “miracle” baby while removing the 22-pound tumor.
Her son’s first days were spent in the neonatal intensive care unit, where specialists monitored the effects of developing outside the uterus and behind such a large mass. Yet despite the precarious start, accounts describe a baby who surprised caregivers with his strength and stability, reinforcing the sense that his survival was as improbable as it was hard-won. The hospital’s own framing of the case as a medical miracle, echoed in multiple retellings of how he was located outside of the uterus behind the tumor, has also become a cautionary tale about listening to patients, investigating unexplained symptoms, and recognizing that even in an era of advanced imaging, the human body can still surprise the experts.
