**Core Concept**
Wallenberg's syndrome, also known as lateral medullary syndrome, is a neurologic disorder caused by a stroke in the vertebral or posterior inferior cerebellar artery that affects the lateral part of the medulla oblongata. This results in damage to the inferior cerebellar peduncle, spinothalamic tract, and the nucleus ambiguus, among other structures.

**Why the Correct Answer is Right**
Wallenberg's syndrome typically presents with a combination of cranial nerve deficits, including ipsilateral hoarseness (due to involvement of the nucleus ambiguus), dysphagia, and Horner's syndrome (ptosis, miosis, and anhidrosis). Additionally, there is often a contralateral loss of pain and temperature sensation in the face and body (due to damage to the spinothalamic tract). Other features may include ataxia, nystagmus, and dysarthria.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a feature of Wallenberg's syndrome.
**Option B:** This option is not a feature of Wallenberg's syndrome.
**Option C:** This option is not a feature of Wallenberg's syndrome.

**Clinical Pearl / High-Yield Fact**
One key feature to remember is that Wallenberg's syndrome typically spares the medial lemniscus, which carries fine touch and proprioception, resulting in preservation of these sensations.

**Correct Answer:** A.
