What complication can arise from immature WBC infiltration in the brain of a leukemia child?

Immature white blood cell (WBC) infiltration in the brain of a child with leukemia can lead to neurological symptoms primarily due to increased intracranial pressure (ICP). As these malignant cells infiltrate the central nervous system, they can disrupt normal brain function and lead to swelling. The accumulation of cells and potential inflammation can create pressure in the cranial cavity, contributing to symptoms such as headache, nausea, vomiting, and altered levels of consciousness.

The presence of increased ICP is particularly concerning because it can result in further neurological damage if not addressed. Neurological symptoms might manifest as changes in behavior, motor function, or cognitive abilities, which are direct consequences of the elevated pressure on brain structures.

While seizures and chronic headaches are possible complications associated with neurological issues, the fundamental problem in this scenario would be the increase in intracranial pressure resulting from the infiltration of immature WBCs. Increased blood pressure is not directly related to this complication, as it is more associated with systemic effects rather than localized intracranial conditions.
