What potential complication can arise from a depressed skull fracture?

A depressed skull fracture can lead to several complications, and one notable risk is pneumocephalus. This occurs when air enters the cranial cavity, often as a consequence of a fracture involving the sinus cavities. If the fracture is located near the frontal or sphenoid sinuses, it can permit the entry of air from the sinus space into the intracranial area, resulting in pneumocephalus.

The clinical significance of pneumocephalus can include symptoms such as headache, altered consciousness, and potentially more severe neurological deficits depending on the extent of the air accumulation and any associated brain injury. Immediate evaluation and management are critical to address this complication and ensure that any associated intracranial injuries are effectively treated.

While the other options may present symptoms related to cranial injuries, they do not specifically highlight the direct and critical condition that is associated with a depressed skull fracture.
