Wendy spends a summer day outdoors and starts feeling unwell, developing a headache she attributes to the heat.

• Wendy and her friends enjoy summer activities in a park.
• She begins to feel sick, starting with a headache, and decides to go home.
• Despite taking aspirin and trying to rest, Wendy's headache persists and worsens overnight.

Wendy's headaches intensify, causing her to seek medical help where she is initially diagnosed with sunstroke.

• Wendy attempts to go to work but is overwhelmed by pain and distress.
• She is taken to the emergency room by her sister Paola.
• Doctors perform a physical exam and conclude that Wendy's symptoms are due to sunstroke and dehydration.

Despite initial diagnoses, further tests reveal Wendy has parasites in her brain, causing severe swelling.

• Paola, not convinced by the initial diagnosis, insists on a brain scan for Wendy.
• The MRI scan reveals brain swelling and the presence of 10-15 parasites.

Neurologist Dr. Carlos Pardo evaluates Wendy's condition, diagnosing hydrocephalus and recommending surgery.

• Dr. Pardo assesses the scans and finds abnormal ventricle structures and fluid accumulation.
• The diagnosis of hydrocephalus leads to the decision that emergency brain surgery is necessary.

Wendy undergoes a risky operation to relieve brain pressure, with the understanding that the parasites cannot be removed.

• Surgeons perform surgery to redirect the fluid in Wendy's brain to alleviate pressure.
• The surgery is not intended to remove the parasites but to save Wendy's life.

Wendy recovers from surgery and returns to normal life, but the parasitic cyst will remain in her brain indefinitely.

• Post-surgery, Wendy is swollen and bears a surgical wound, but is conscious and safe.
• Months later, Wendy fully recovers, except for the permanent presence of the cyst in her brain.
