Panhypopituitarism diagnosed in adulthood: Imaging findings of bone and other organs

A 38-year-old man who was delivered in a breech position presented with delayed development of secondary sexual characteristics and malaise. He was diagnosed with panhypopituitarism caused by interruption of the pituitary stalk due to perinatal complications. Brain magnetic resonance imaging findings for pituitary stalk interruption syndrome are well-documented; however, reports of the imaging findings of the bones and several organs related to the effects of panhypopituitarism are limited. In this patient with anterior pituitary dysfunction, imaging revealed diverse sequelae, including delayed skeletal maturation, osteopenia, genital atrophy, fatty liver, and adrenal atrophy. Radiologists may find it difficult to discern complex imaging findings unless they are informed of the clinical course of the patient. Therefore, radiologists should coordinate with clinicians to arrive at a diagnosis.
