Question

Syndrome associated with posterior inferior cerebellar artery thrombosis:

• A. Wallenberg syndrome
• B. Medial medullary syndrome
• C. Inferior alternating syndrome
• D. Dejerine syndrome

Answer 1

The Correct Option is A

The question pertains to identifying the syndrome associated with posterior inferior cerebellar artery (PICA) thrombosis. This can be understood by examining the symptoms and areas affected by the syndrome.

Wallenberg syndrome, also known as lateral medullary syndrome, is directly associated with the occlusion or thrombosis of the posterior inferior cerebellar artery. This leads to a range of clinical symptoms due to the affected areas in the lateral part of the medulla oblongata where the blood supply is disrupted.

The symptoms of Wallenberg syndrome typically include:

• Vertigo and nausea
• Loss of pain and temperature sensation on one side of the face (ipsilateral) and the opposite side of the body (contralateral)
• Dysphagia (difficulty swallowing)
• Horner's syndrome (ptosis, miosis, anhidrosis)
• Hiccups
• Ataxia (lack of voluntary coordination of muscle movements)

Understanding these symptoms helps in diagnosing Wallenberg syndrome as related to PICA thrombosis. In contrast, the other options presented, such as Medial medullary syndrome, Inferior alternating syndrome, and Dejerine syndrome, are associated with different vascular occlusions and present with different symptom patterns.

Therefore, the correct answer is Wallenberg syndrome.
