Abstract
Background:
Subsequent bilateral intracerebral hemorrhage (SBICH) in the putamen and thalamus is a rare condition. Herein, we report four such cases.
Case Description:
Case 1: A 47-year-old woman presented with the left hemiparesis and elevated blood pressure. Neuroimaging revealed a right thalamic hemorrhage and a small left thalamic hemorrhage accompanying the hyperdense rim on computed tomography (CT) and the hypointense rim on gradient-echo T2*-weighted imaging (T2*WI). Case 2: A 53-year-old man presented with a disturbance of consciousness and elevated blood pressure. Neuroimaging revealed a left putaminal hemorrhage and a small right thalamic hemorrhage that appeared hyperdense on CT and hypointense on T2*WI. Case 3: A 65-year-old woman presented with the right hemiparesis and elevated blood pressure. Neuroimaging revealed a left putaminal hemorrhage and a small right thalamic hemorrhage accompanied by a hyperdense rim on CT and a hypointense rim on T2*WI. Case 4: A 75-year-old woman presented with the right hemiparesis and elevated blood pressure. Neuroimaging revealed a left thalamic hemorrhage and small hemorrhages in the right thalamus and cerebellar hemisphere. These hemorrhages appeared hyperdense on CT and hypointense on T2*WI.
Conclusion:
SBICHs are rare bilateral hemorrhages that may present with asymptomatic microbleeds in the putamen or thalamus coupled with symptomatic, subsequent hemorrhages in the contralateral counterparts. The latter hemorrhage may develop during the subacute phase of microbleeds in the putamen or thalamus.
