Abstract |
We describe a rare midbrain stroke presenting with predominantly sensory symptoms. A 71-year-old woman was hospitalized due to the recurrence of faciobrachial sensory loss. Magnetic resonance imaging showed an infarct involving the right side of the middle portion of midbrain at the level of the inferior colliculus. In our case we tried to make some clinico-anatomical correlations. The main anatomical structures involved were the medial lemniscal tract, the ventral part of the spinothalamic tract and the trigeminothalamic tract. The location of the stroke would suggest there are overlaps between arterial territories of the midbrain. Clinicians should look for midbrain infarcts in cases of pure sensory stroke.
