case_images: MRI 1 month after the onset of symptoms of uropathy (A) showed loss of the posterior pituitary bright spot and findings of pituitary stalk thickening; contrast-enhanced MRI 2 months later (B) showed slightly progressive swelling of the pituitary stalk, but MRI 4 months after the onset of symptoms confirmed disappearance of the thickening of the pituitary stalk (C). MRI findings at 5 years of age showed a further trend of improvement in pituitary enlargement (D).

case_images: T1-weighted imaging MRI of the head showed loss of the bright spot in the posterior pituitary gland and thickening of the pituitary stalk (Fig. 1A), leading to a diagnosis of AVP-D. Contrast-enhanced MRI was performed for the thickened pituitary stalk, and the pituitary gland exhibited diffuse enhancement in the early phase, with no obvious areas of poor contrast in the pituitary/pituitary stalk (Fig. 1B).
