1. Clinical presentation and history taking
A detailed history is obtained regarding headache, visual changes, polydipsia/polyuria, and growth patterns in children to guide subsequent investigations.
2. Comprehensive neurological examination
Visual acuity and visual fields, extraocular movements, balance/coordination, and reflexes are assessed to preliminarily determine the affected neuroanatomical regions.
3. Hypothalamic–pituitary endocrine function assessment
Blood testing of multiple hormonal axes directly evaluates the degree of endocrine axis compromise due to tumor-related compression.
4. Quantitative visual acuity and visual field testing
Perimetry precisely maps the extent and pattern of visual field defects, assessing optic pathway compression and urgency for surgical intervention.
5. MRI
Sellar-region MRI with non-contrast and contrast-enhanced sequences is the core modality, delineating the tumor’s relationship to the optic chiasm and hypothalamus.
6. CT
Thin-slice CT demonstrates characteristic calcifications and evaluates skull base bony anatomy relevant to surgical corridor planning.
7. Differential diagnosis
Differentiation from pituitary adenoma, sellar meningioma, and other entities is required; MRI characteristics and CT-detected calcification are key discriminators.
8. Pathological diagnosis
Postoperative histopathology is the gold standard, confirming subtype and guiding subsequent targeted treatment strategies.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that although craniopharyngioma is benign, it can lead to catastrophic outcomes such as vision loss and growth arrest. A systematic and comprehensive diagnostic workup is the first step toward effective treatment. Early, accurate diagnosis is the foundation for preserving neurological function and developing individualized management strategies.
