Case contributed by Dr Gregor Savli


Patient who had plasmacytoma, platelet count of 80 and INR 1.3, presented with coma, GCS 3.

Patient Data

Age: 70
Gender: Male

Almost pure primary intraventricular hemorrhage is seen on the initial non-contrast scan. There is only a small amount of blood in the cerebellopontine cistern. There is no blood elsewhere.

On CTA, the cause was identified - a small, 3.5 mm wide, left PICA aneurysm (or possibly pseudoaneurysm, the patient unfortunately expired prior to DSA) in its supratonsillar segment, which manifested itself as a pure intraventricular hemorrhage.
