Delayed Presentation of Subdural Hematoma.

In brief A 72-year-old man and a 47-year-old woman presented with subdural hematomas more than a month after repeated head injuries incurred while skiing. Neither had lost consciousness. The man had remained asymptomatic for 3 weeks, then had developed a bifrontal headache of increasing intensity and frequency. CT scan revealed a large left subdural hematoma. The woman had experienced intermittent symptoms, including headache, light-headedness, paresthesias, and lower-extremity weakness, for 4½ months before MRI revealed bilateral hematomas. Acute hemorrhage into a chronic subdural hematoma may explain the delayed onset of symptoms in these patients.
