Case Reports
[Two cases of acute idiopathic subdural hematoma with delayed intracranial hypertension].
Two cases of acute idiopathic subdural hematoma with delayed intracranial hypertension were presented. The first case was a 68-year-old man admitted for vomiting following headache for eight days. There was no history of head trauma. ⋯ The delayed intracranial hypertension appeared in these two cases about 10 days after the initial symptom. Two kinds of mechanisms are suspected: 1) swelling of the hematoma because of the adsorption of cerebrospinal fluid, 2) the occurrence of secondary brain edema. From our experience, a repeated CT scan is necessary for 2 to 3 weeks.(ABSTRACT TRUNCATED AT 250 WORDS)
