Introduction
Cerebral contusion and laceration refer to mechanical injury to brain tissue caused by external force applied to the head, encompassing both contusions and lacerations. Such injuries may occur at or near the site of direct impact—termed “coup injury”—but more commonly and severely manifest at locations opposite the impact site (i.e., the contralateral side), resulting in severe “contrecoup injury.”
Cerebral contusion-laceration refers to mechanical injury to brain tissue caused by external force applied to the head, encompassing both contusions and lacerations. It is the most common gross anatomical and CT-documented lesion following traumatic brain injury (TBI), frequently co-occurring with other types of intracranial injuries.
What Is Pediatric Cerebral Contusion-Laceration?
Cerebral contusion-laceration may occur at or near the site of direct impact—termed a “coup injury”—but more commonly and severely manifests at the brain region opposite the impact site—the “contrecoup” location—resulting in significant contrecoup injury.
Severe cerebral contusion and laceration confirmed by CT or MRI—characterized by local fragmentation and necrosis of brain tissue, marked cerebral edema, and elevated intracranial pressure—may progressively worsen despite maximal medical therapy. When signs of cerebral herniation emerge—even in the absence of an intracranial hematoma—aggressive surgical intervention is warranted. This includes removal of contused and fragmented brain tissue, evacuation of small clots, and, if necessary, resection of the frontal or temporal pole. Subsequent decompressive procedures—such as subtemporal or craniectomy decompression—may be performed based on the severity of cerebral edema. Postoperatively, comprehensive supportive care must continue. In cases where cerebral contusion-laceration is complicated by hydrocephalus, initial ventricular drainage is indicated to identify the underlying cause of CSF accumulation, followed by targeted treatment.
Management of cerebral contusion-laceration primarily involves either surgical or non-surgical approaches. Non-surgical management focuses on mitigating secondary pathophysiological cascades following brain injury. Close monitoring for secondary intracranial hematoma or thromboembolic complications—especially hematoma formation—is essential, along with maintaining physiological homeostasis and preventing systemic complications. Surgical intervention is generally unnecessary unless secondary intracranial hematoma develops or refractory intracranial hypertension requires urgent decompression.
