mrs_angemi Forensic Friday!!!!!! My favorite day of the week. And my favorite subject, brain bleeds!!!! If we do the entire autopsy of the thoracic, abdominal and pelvic cavities and everything looks normal and we do not find the cause of death, the answer may be in the head. The brain is not just a squishy organ that is present in the skull. It has very delicate anatomy, and when trauma and natural disease occur, we can look at the brain to determine exactly what caused the patient to die. Remember all my explanations of disease are brief summaries because I only have so much space to write! I like to explain brain bleeds starting with the outer most layer that is seen when the skull cap is removed and then work my way in. After using the bone saw and removing the skull cap, the first space in the cranial cavity is called the epidural space. This is between the skull itself and the dura mater which is a thick fibrous layer of tissue over the brain. Between this space is the middle meningeal artery. If trauma occurs to the head causing this artery to tear or get severed, the patient is in trouble. This injury usually occurs from blunt force trauma to the head that results in a skull fracture that severed this artery. Because this is an artery that is leaving the heart, as the heart pumps blood it is shooting blood fast in this space. This is called an epidural hematoma (upper left). This happens fast and the fast accumulation of blood causes the brain to compress and the patient dies rather quickly. The next space in the cranial cavity is between the dura mater and the brain called the subdural space. There are bridging veins that attach the dura to the brain. If these veins are injured, the blood will slowly leak into this space, because this is from veins bringing blood back to the heart rather than pumping from the heart. This bleed is usually caused by trauma such as a fall that causes the brain to shake vigorously and tear from the dura. This can also occur naturally in patients that are elderly with brain shrinkage. This is called a subdural hematoma (upper right). A subdural hematoma takes hours to form and will cause the patient to have a terrible headache. 4h

knightoftheoldcode I wonder if that hole was made by a #labotomy, a #gunshotwound, or some other kind of #bluntforcetrauma. #skulls #desCatacombes #thecatacombs #Paris 1w
