A 56-year-old man presents with a stroke affecting the right internal capsule. Which of the following neurological deficits is most characteristic of this lesion?
- A.Contralateral spastic hemiplegia and contralateral hemisensory lossCorrect answer
- B.Ipsilateral spastic hemiplegia and contralateral lower facial weakness
- C.Contralateral flaccid paralysis with hyperreflexia limited to the upper limb
- D.Bilateral loss of pain and temperature sensation below the neck
Solution
The internal capsule carries dense fiber bundles including the corticospinal tract and thalamocortical radiations (posterior limb). A lesion here typically causes contralateral hemiplegia, contralateral hemisensory loss, and often contralateral homonymous hemianopia due to involvement of the optic radiation.
