Abstract

We present a case of isolated fourth ventricle which developed after massive ventricular hemorrhage, due to a ruptured cerebral aneurysm. In an adult an isolated fourth ventricle seems to be very rare, also the symptom of unconsciousness and respiratory arrest and the rapid development in this case seemed very unusual. The aqueductal occlusion was considered to be related to the intraventricular hematoma which remained as clots over a 2-month-period of time. This case was a 57-year-old woman admitted to our hospital in a state of coma. CT showed a massive ventricular hematoma and right carotid angiogram showed an aneurysm of the anterior communicating artery. Bilateral ventricular drainage was performed because of progressive decerebrate rigidity. Since consciousness gradually arose to the Japan Coma Scale 3, clipping of the neck of the aneurysm was performed 25 days after onset. Premature rupture occurred during the operation. After surgery, CT Showed ring-like high densities due to the premature rupture of aneurysm in both lateral ventricles, and also in the fourth ventricle as well. Although the lateral ventricles drainage functioned effectively, the fourth ventricle showed remarkable gradual dilatation. The patient was stup...Continue Reading

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
