The examination this time revealed a mass growing on the right side of the patient's kidney.
Experts must have been very excited.
They immediately performed a laparoscopic surgery on the patient, removing the suspect tumor mass.
The pathological test identified it as a teratoma.
Experts at the Provincial Children's Hospital, full of hope, thought that they had finally found the cause of the illness and surgically removed the tumor. Surely the child's illness should be cured by now?
According to Murphy's Law, things tend to go wrong in the worst possible way.
The child's mass was removed, and the biopsy results did indeed suggest a tumor. However, the child's symptoms did not improve: the vomiting persisted, and the diarrhea continued.
Such an odd occurrence was probably a first for the expert at the Provincial Children's Hospital.
What to do then?
