This reactive scarring process is accompanied by endothelial proliferation along the dural margins of the clot. She was a fussy infant with bulging fontanelle that was tense. It is pertinent to note that these studies also do not mention the specific radiological methods applied in estimating the age of the subdural haematoma. When interacting with patients and their families, blitz dating the health care professional communicates effectively and demonstrates caring and respectful behaviors.
Common sites for subdural hematomas are frontoparietal convexities and the middle cranial fossa. These cases were admitted to the emergency neurosurgery department with confirmed history of head trauma, known topography, exact manner, mode and time since the trauma. Because of this, timing of subdural hematomas should be done based on utilizing imagining findings combined with taking into consideration the onset, progression and severity of clinical findings. Bilaterally eyes were adducted and did not appear to be able to full abduct. The clinical, as well as police records of the patients, were reviewed and the time interval between the occurrence of trauma and Non-contrast computed tomography was noted.
An investigatory and analytic thinking approach to the clinical situation is demonstrated. Another acute subdural hematoma was noted in the left posterior fossa not pictured. All the above studies have tried to classify subdural haemorrhage into acute, subacute or chronic depending on the attenuation.

- Both will appear white and the hemorrhage will merely look like a thicker skull.
- There is acute hemorrhage with alarge number of neutrophils seen on the dural side.

The neurosurgeons would then aspirate the subdural fluid through the anterior fontanelle with relief of the tension and stopping of the emesis. The appearance of a hematoma varies with the biochemical state of hemoglobin which varies with the age of the hematoma. Birth trauma should be considered as a potential cause of subdural hematomas.

The radiologic evaluation showed bilateral chronic subdural hematomas that also had newer blood within them. She was not able to fixate on a light. In this study, dutch free crescent shaped haemorrhages were distinctively selected to determine the effect of blood volume on attenuation. It may appear biconvex-shaped on the coronal plane rather than crescent-shaped which is a typical appearance on the axial plane. Conclusion The density of the subdural haematoma decreases with increase in the post-traumatic interval that concurs with the limited number of studies being conducted in the past.
