Subarachnoid haemorrhage

Case contributed by Dr David Cuete

Presentation

Disorientation, headache of sudden onset.

Patient Data

Age: 80
Gender: Female
Modality: CT

CT image shows diffuse subarachnoid haemorrhage in all basal cisterns, bilateral sylvian fissures and inter-hemispheric fissure with a component of left subdural hematoma.

CT brain - Patient was scanned 5 days after.

Modality: CT

Control CT  5 days after shows partial absorption of the subarachnoid hemorrhage with a decrease in attenuation coefficient compared to the first study.

Case Discussion

This case shows a subarachnoid haemorrhage with a subdural haemorrhage component. We see a favourable evolution with reabsorption of the haemorrhage and without signs of complications. 

In the evolution of intracranial haemorrhage on computed tomography, we expect a decrease of the blood density of 1.5 HU per day.
