Post-traumatic subdural hygroma: Case report

Normal pressure subdural hygroma with mass effect as a complication of decompressive craniectomy

“…[1019232427] High dynamic accidents and diffuse traumatic brain injuries have been pointed out as risk factors for a subdural hygroma (SDG) following DC. [6–8101216182325] On the other hand, duraplasty at the time of DC has been observed to lower the incidence of TSH. [11723] Most of these collections resolve spontaneously,[12425] as the need for surgical evacuation of the collection is low in different series ranging from 30 to 8%.…”

Acute enlargement of subdural hygroma due to subdural hemorrhage in a victim of child abuse

“…Subdural hygroma (SDH) is characterized by subdural fluid collection whose CT value is between 10 HU and 16 HU, or less than 20 HU [1][2][3]. The ages of patients with SDH are diphasic; children aged less than 10 years, particularly less than 2 years, or men aged above 60 years, which may be attributed to the broad subdural space of children and elderly people [4,5].…”

“…The ages of patients with SDH are diphasic; children aged less than 10 years, particularly less than 2 years, or men aged above 60 years, which may be attributed to the broad subdural space of children and elderly people [4,5]. Whereas SDH is a common complication of blunt head injuries in adults, the etiology of SDH in infants and children has been reported as surgical procedure, complications of leptomeningeal infections or unexplained, in addition to post-traumatic [1,4]. Although the subdural fluid would be considered cerebrospinal fluid (CSF) and leak from the subarachnoid space through a damaged arachnoid membrane, expanding into the subdural space, it can sometimes appear xanthochromic, yellow or slightly hemorrhagic [2,5].…”

“…Moreover, subdural fluid collection might be related to the impairment of CSF absorption by arachnoid granulations [2,3]. In other words, SDH occurs traumatically, spontaneously or post-surgically, and its pathogenesis is still unclear [1][2][3][4][5][6].…”

The comparison between surgical procedure and conservative treatment in the management of traumatic subdural effusion

“…Poor prognosis appears when mass effect, serious brain injury or intracranial hematoma occur, and the mortality is high (1,2,4). █ InTRODuCTIOn T raumatic subdural effusion is a common disease, and has a high percentage in traumatic head injury cases (2,4,7,12,19,20). Traumatic subdural effusion occurs AIm: Traumatic subdural effusion (TSE) occurs following traumatic brain injury and may be treated by either conservative methods or surgical procedure commonly according to the patients' clinical information.…”
