A case of sudden death from primary intracranial germinoma complicated by microvascular disease of the heart

A coroner's autopsy conducted on an 11.5-year-old girl, with a history of hypopituitarism, manifesting as growth hormone deficiency associated with short stature, demonstrated the presence of an undiagnosed hypothalamic intracranial germinoma, showing hypophyseal and mesencephalic invasion, together with histological evidence of microvascular (small coronary artery) disease of the heart. The substantive, or primary, cause of her sudden death was clearly the intracranial germinoma, which was acutely haemorrhagic and necrotic. However, it is postulated that there might be an, as yet, undescribed association between this malignancy and the pathogenesis of the coronary microvascular disease; the latter being deemed, in this instance, to be a contributory cause of death.
