Case Reports
[Ipsilateral exophthalmos in chronic extradural fluid-hematoma, case report (author's transl)].
A case of chronic extradural hematoma with liquid contents that had showed ipsilateral exophthalmos was reported. A 10-year-old girl fell and struck on her head. Neurological examination, on admission to our hospital on tenth day after the injury, revealed left exophthalmos and slight right hemiparesis. ⋯ The small hematoma might have enlarged by a process similar to that postulated in chronic subdural hematoma. Thus a huge extradural hematoma with liquid contents might have been produced. There may be two factors as causes of exophthalmos. 1) Blood from the frontal extradural hematoma through the fracture of orbital roof into the orbit is postulated to have compressed the periorbita. 2) Direct pressure by the frontal hematoma on the cavernous sinus and the superior ophthalmic vein produced venous circulatory disturbance of the orbit and was postulated to have caused the ipsilateral exophthalmos.
