Pediatric abdominal tumours often lack typical symptoms and can be characterised by painful abdominal pain, and most are characterised by painless masses.
Most cases are discovered unintentionally by parents when bathing or changing the child, or by physicians on physical examination during visits for other illnesses. The common symptoms of the disease include weight loss, loss of appetite, irregular fever, abdominal distension and paroxysmal abdominal pain. When the tumour grows, it may compress the surrounding organs, causing nausea, vomiting and abdominal bulging.
Once an unexplained mass is found in the abdomen of a child, prompt medical attention should be sought and imaging tests such as ultrasound, CT and MRI should be performed to clarify.
