Pituicytoma MRI Diagnosis: Suprasellar Tumor Imaging, Differential Diagnosis, and Treatment Strategy
Introduction: Why Pituicytoma Matters in Modern Neuroimaging In the era of high-resolution MRI and AI-assisted radiology , rare sellar and suprasellar tumors such as pituicytoma are increasingly recognized. Although classified as a WHO Grade 1 tumor , its diagnostic complexity and surgical challenges make it highly relevant for radiologists, neurosurgeons, and endocrinologists . This article delivers a world-class, expert-level yet reader-friendly analysis of pituicytoma , based on the provided case and latest literature.
