Pituitary stalk lesions refer to abnormalities affecting the pituitary stalk, which connects the hypothalamus to the pituitary gland, potentially disrupting hormone regulation. Clinically significant due to their impact on endocrine function, these lesions can lead to conditions such as hypopituitarism or diabetes insipidus. A key association is with craniopharyngiomas, which can compress the stalk and cause visual disturbances and hormonal imbalances.
