Pituitary adenoma and unexpected sudden infant death: a case report.
Pituitary adenomas can cause sudden death in adults, but they are quite rare during infancy. Herein we present an unusual case of sudden infant death associated with a pituitary adenoma. The clinical presentations were "quietness" complained of by the parents and probable gigantism with accelerated growth rate during the first 2 months of life. The female infants had been in good health until one day when, at the age of 3 months, she was found immobile in bed. Microscopic examination showed that the cells of the entire pituitary gland were replaced by bizarre undifferentiated tumor cells. There were no invasive lesions in the surrounding brain tissue. It was also found that the cortex of the adrenal glands was atrophic. No metastatic lesions were observed in any organ. While the mechanism leading our infant to death is both controversial and unknown, we speculated that insufficient secretion of steroid hormones might have caused cardiovascular collapse.
