[Intracranial hemorrhage in mature infants without predisposing factors].

Four mature infants developed intracranial haemorrhage at ages from ten hours to five weeks. No predisposing or provoking factors could be demonstrated. The symptoms were apnoea, vomiting, pyrexia, irritability, tremor, hypertonicity, seizures and tense fontanelle. The diagnosis was established by ultrasound scanning and confirmed by computed tomographic scanning. The infants developed hydrocephalus requiring treatment. During the period of observation, these infants showed normal psychomotor development and the neurological findings were normal.
