Case contributed by Dr Pawel Piotrowicz


Sudden loss of consciousness with seizure. High blood pressure.

Patient Data

Age: 65 years
Gender: Female

Massive SAH extending into brain parenchyma and ventricular system.

After contrast media administration an irregular 5 x 4 mm ACom aneurysm was visualized. On the upper surface of the aneurysm there are two Murphy's teats - signs of the recent rupture of the aneurysm.

Case Discussion

An aneurysm with a diameter of less than 7 mm has a very low chance of rupture but as shown in this case, even such a small lesion can cause a severe medical condition.
