What manifestation is expected in a child diagnosed with Wilm tumor?

Wilm tumor, also known as nephroblastoma, is a type of kidney cancer predominantly found in children. One of the notable manifestations associated with this condition is hypertension. This can occur for several reasons, primarily related to the tumor's effects on kidney function and the renin-angiotensin system.

In the case of a Wilm tumor, the tumor itself may disrupt the normal filtration and fluid balance processes of the kidneys, which can lead to fluid overload and increased blood pressure. Additionally, the presence of a large mass can cause mechanical obstruction and changes in the hemodynamics of the renal vasculature, further contributing to elevated blood pressure.

Other options, while they may present in various clinical situations, are not common manifestations directly related to a Wilm tumor. Atrial fibrillation, for example, is typically associated with underlying heart conditions or disorders rather than renal tumors. Endocarditis is an infection of the heart's inner lining and usually relates to bacterial infections, not tumors. Lastly, hyperlipidemia, characterized by high levels of lipids in the blood, is generally linked to metabolic disorders or lifestyle factors rather than being a direct consequence of a Wilm tumor.

Thus, hypertension stands out as a significant and relevant manifestation for children diagnosed
