Hippocampal Microbleed on a Post-Mortem T(2)∗-Weighted Gradient-Echo 7.0-Tesla Magnetic Resonance Imaging?

The present post-mortem study of a brain from an Alzheimer patient showed on a T(2)∗-weighted gradient-echo 7.0-T MRI of a coronal brain section a hyposignal in the hippocampus, suggesting a microbleed. On the corresponding histological examination, only iron deposits around the granular cellular la...

description The present post-mortem study of a brain from an Alzheimer patient showed on a T(2)∗-weighted gradient-echo 7.0-T MRI of a coronal brain section a hyposignal in the hippocampus, suggesting a microbleed. On the corresponding histological examination, only iron deposits around the granular cellular layer and in blood vessel walls of the hippocampus were observed without evidence of a bleeding. This case report illustrates that the detection of microbleeds on MRI has to be interpreted with caution.
