What brain tumor is associated with headaches and hypothyroid symptoms in children?

The correct answer is craniopharyngioma, which is often associated with headaches and hypothyroid symptoms in children. Craniopharyngiomas are benign tumors that typically arise from epithelial remnants of the Rathke's pouch near the pituitary gland. This proximity to the pituitary can lead to disruption of hormonal pathways.

In children, the presence of a craniopharyngioma can cause headaches due to increased intracranial pressure resulting from the tumor's growth. Additionally, because the tumor can interfere with pituitary function, it can lead to hormonal imbalances, including deficiencies in thyroid-stimulating hormone (TSH), which results in hypothyroidism. Symptoms of hypothyroidism in children can manifest as fatigue, weight gain, cold intolerance, and developmental delays, aligning with the hormonal impact that craniopharyngiomas can have.

The other tumor types listed can present with various symptoms but are less frequently associated with the combination of headaches and hypothyroid symptoms specifically. Ependymomas, for example, may lead to headaches due to obstruction of cerebrospinal fluid flow, but they do not typically cause hypothyroidism. Medulloblastomas are more common in the posterior fossa and are characterized by symptoms related to
