Intracranial haemorrhage from arteriovenous malformation

Case contributed by Dr Henry Knipe

Presentation

Sudden onset of worst-ever headache. No history of trauma.

Patient Data

Age: 30 years
Gender: Male

Intraventricular haemorrhage with a small volume of right parietal subarachnoid haemorrhage. No midline shift. No hydrocephalus. 

Right parietal lobe arteriovenous malformation extend from cortex to the right lateral ventricle with a nidus length of approximately 5 cm. Dominant arterial supply from a distant pericallosal branch of the right anterior cerebral artery. Deep venous drainage (via right internal cerebral vein and basal vein of Rosenthal) as well as superficial venous drainage (via right vein of Trolard and superior sagittal sinus). 

Case Discussion

The pattern of blood is atypical for the usual causes of intracranial haemorrhage - trauma and berry aneurysms, and this should prompt close evaluation for other causes such as arteriovenous malformations (AVMs).
