| Case Scenario|| |
A 43-year-old female presenting with double vision was admitted to our hospital. She reported that this symptom started within 1 month and have periods of exacerbation with worsening throughout the day. Her family history was unremarkable and negative for neurological disorders. She had well-controlled essential hypertension with a changing lifestyle. On neurological examination, the inspection showed ptosis without other cranial nerve abnormalities. The sustained upgaze test reveals the weakness of the levator palpebrae with intensification of ptosis. Laboratory tests were within normal limits. Brain magnetic resonance imaging was normal. Computed tomography (CT) of the abdomen and chest was performed [Figure 1].
