case_images: Plasma concentrations of sodium. Horizontal axis depicts time course from hospital admission (day 0) until 180 days' follow-up. Vertical axis depicts plasma sodium concentrations (p-Na+). Hyponatremia was treated with intravenous hyperosmolar sodium infusion (3% NaCl at day 2) and fluid restriction (day 2 to day 5). The subsequent development of central diabetes insipidus (CDI) was treated with low dose desmopressin (initiated around day 60).

case_images: During the first two days of admission, plasma sodium concentrations dropped to a nadir level of 111 mmol/l (Figure 1). The patient was treated with fluid restriction (day two to day five) and an intravenous bolus of hypertonic saline 3% (day two only), which induced a gradual increase in plasma sodium concentrations (Figure 1).
case_images: Magnetic resonance imaging of cerebrum. Magnetic resonance imaging (MRI) showed signs of recent bleeding into a cystic adenoma comprising 10x10x8 mm placed in sella turcica with close proximity to the chiasma and displacing the pituitary gland to the right.

case_images: On the third day, a magnetic resonance imaging [MRI] of the brain showed recent bleeding into a cystic process (10x10x8 mm) in the sellar region in close proximity to the optic chiasm with displacement of the pituitary gland to the right (Figure 2).
