Idiopathic intracranial hypertension: Imaging and clinical fundamentals

Figure 3 Partially empty sella and empty sella. The figure displays T2-weighted sagittal images from magnetic resonance scans of different patients. A: A normal pituitary gland with normal height and a convex upper border is presented for reference (dashed circle); B: A pituitary gland with partial height loss, indicating a partially empty sella; C: An almost complete height loss of the pituitary gland, indicating an empty sella, are shown in patients with idiopathic intracranial hypertension (dashed circle). Note how the increased intracranial pressure forces appear to stretch the pituitary gland onto the sella turcica (arrows).
