Acute deterioration and death in infancy due to posterior fossa tumour. A case report

Acute deterioration of a 27-day-old male baby born at term is reported. On admission the baby presented with acute gastro-enteritis which had developed 3 days previously. Apart from enlargement of the head, no signs of CNS dysfunction could be elicited. Only after acute clinical deterioration was a suspicion of a cerebral process aroused. Computed tomography showed a posterior fossa mass and postmortem examination revealed a cerebellar medulloblastoma which was probably of antenatal onset.
