Craniopharyngioma is a relatively insidious tumor with no severe headache or vomiting. The main symptoms include loss of vision, which can easily be mistaken for amblyopia or blurred vision caused by stressful learning or poor rest, or even delayed treatment, leading to blindness and life-threatening conditions in children. Craniopharyngioma is the most common intracranial congenital tumor in children, with 70% of them occurring in children under 15 years old. It is a tumor of embryonic remnant tissue that originates from residual squamous epithelial cells of the primitive craniopharynx. The tumor is benign. The tumor grows slowly. The first symptom of craniopharyngioma in children is vision loss, and visual field disturbance is common, but it is easily ignored by parents because of the child’s limited self-perception and self-describing ability. The disease is often associated with endocrine disorders. Abnormalities in a child’s physical, visual, and intellectual development must be brought to the attention of parents and teachers regardless of how they occur. Early detection of craniopharyngioma can be achieved by taking the child to a hospital specialist.
