A patient with polyuria and polydipsia is newly diagnosed with central diabetes insipidus (DI). Which of the following is the most likely finding on magnetic resonance imaging (MRI) of the brain?
Correct Answer: lack of hyperintense signals from the posterior pituitary
Description: Because diabetes insipidus is usually caused by destruction, or agenesis, of the posterior pituitary, its normal signaling is lost. Pituitary diabetes insipidus can also result from trauma, tumors (both primary and secondary), granulomas, infections, inflammatory diseases, chemical toxins, congenital malformations, and genetic disorders.Depending on the cause, the MRI may demonstrate other associated findings.
