Acute Subdural Haematomas (ASDH) have great forensic significance, because a wide spectrum of forces (usually head trauma) can cause them. Chronic subdural haematoma (CSDH) is also an important condition, which does not necessarily imply a recent trauma. The authors report the case of a 73 year-old man, with repeated craniocerebral trauma, hospitalized with right ASDH and left CSDH, who died within 12 hours after admission. The autopsy revealed, at external examination, a lacerated wound in the right parietal region and multiple abrasions and bruises; on internal examination, right ASDH and left CSDH with recent bleeding and left midline shifting. Sometimes, in cases of repeated assault it is possible to discover acute-on-chronic subdural haematoma (ACSDH), explained by recent bleeding, usually near the anterior part of the haematoma. Such cases require the attention of the forensic pathologist who should search for signs of recent brain trauma which aggravated an underlying condition or caused death; also, histological sampling can provide important forensic information
