Basal ganglia bleed

Case contributed by A.Prof Frank Gaillard
Modality: CT

Axial non contrast CT image demonstrates a hyperdense focus centered on the globus pallidus on the left with a faint rim of low attenuation. Findings are characteristic of a basal ganglia haemorrhage

Modality: MRI

MRI obtained a few days later variable signal consistent with the subacute timing. The majority of the bleed demonstrates high T1 and T2 signal consistent with extracellular met-Hb, with a peripheral rim of low signal (best seen on gradient echo) representing hemosiderin. 

Time of flight MRA demonstrates the bleed as a globular region of high signal which should not be misinterpreted as flow. 

Case Discussion

Spontaneous basal ganglia bleed in a known hypertensive. CT performed on the day of presentation. MRI a few days later.
