Presentation
Quadriparesis with dysarthria.
Patient Data
Nonspecific periventricular hypoattenuation seen in bilateral centrum semiovale likely chronic small vessel ischaemic changes.
Since no definite acute focus was identified, DWI MRI was recommended.
Heart-shaped diffusion restriction is seen involving bilateral medial medulla. Another acute focus seen in right periventricular region.
Nonspecific periventricular arteriosclerotic leukoencephalopathy. Old right pontine infarction.
Case Discussion
Classic heart-shaped bilateral medial medullary stroke was identified well in the MRI DWI imaging. Initially the right corona radiata infarct was only identified, but the clinical presentation of this patient correlates with the medullary infarction.
This is an area which is quite easily overseen by radiologists due to its caudal location and where artifacts are high, but with the right clinical presentation and early radiological diagnosis, we might be able to salvage irreversible tissue loss.
