Question

Patient with limited upward gaze, upper eyelid retraction, and pupils that are non-reactive to light but reactive to accommodation as well as obstructive hydrocephalus:

a) Wernicke encephalopathy
b) Miller Fisher syndrome
c) Guillain-Barré syndrome
d) Parinaud syndrome (dorsal midbrain syndrome)

Answer 1

Parinaud syndrome (dorsal midbrain syndrome) is the likely diagnosis in this case, based on the patient's symptoms of limited upward gaze, upper eyelid retraction, non-reactive pupils to light but reactive to accommodation, and obstructive hydrocephalus(option d).

Step-by-step explanation:

The patient's symptoms of limited upward gaze, upper eyelid retraction, non-reactive pupils to light but reactive to accommodation, and obstructive hydrocephalus are indicative of Parinaud syndrome (dorsal midbrain syndrome).

Parinaud syndrome is caused by a lesion or dysfunction in the dorsal midbrain, which affects the superior colliculus and the pretectal area. This can result in impaired upward eye movements, eyelid retraction, and abnormal pupillary responses.Therefore the correct answer is option d) Parinaud syndrome (dorsal midbrain syndrome)
