Abstract Haemochromatosis is a disease characterised by iron deposition in the liver and other organs. Hypogonadism is a commonly associated condition and may be either primary due to testicular lesions or secondary due to pituitary dysfunction. Hypogonadism secondary to pituitary dysfunction is more frequent and is thought to be related to iron deposition in the anterior pituitary. Increased iron content decreases signal intensity of spin-echo MRI images because T2 values are significantly shortened. Our purpose in this study was to evaluate by MRI iron deposition in the liver, testis and pituitary of 6 patients with haemochromatosis and severe hypogonadotrophic hypogonadism. Six subjects sereved as controls. There was a significant T2 shortening of the liver and pituitary i in patients with haemochromatosis compared with control patients. Therefore MRI detected iron overload in the pituitary and no iron in the testis, supporting the hypothesis of hypogonadotrophic pituitary insufficiency due to cellular damage induced by iron overload in the anterior pituitary gland.
