Post-Traumatic Subdural Hygroma: A One Year Follow up Case Report and Literature Review.

Post-traumatic subdural hygroma it is an intracranial lesion, commonly misdiagnosed due to its unclear symptomatology and slow progression. Defined as the presence of cerebral spinal fluid in between the arachnoid and the duramater layers; causing a variety of symptomatology that usually depend on the amount of fluid within this space (subdural). Post traumatic subdural hygroma it's observed in 5-20% of all blunt head injuries, although its diagnosis it's usually rare among emergency departments. Prognosis is usually good due to the absence of severe complications and its spontaneous resolution in mostly of the cases. We present a 26-year-old male patient, with history of high impact blunt trauma, presenting ocular refractive changes and headache. After CT scan evaluation and BOLD-MRI confirmation, a bilateral fronto-parietal subdural hygroma was confirmed.
