TLDR A baby girl's hair turned straight on one side due to a neck tumor and surgery, but it returned to curly as she recovered.
A girl was diagnosed with a multicystic tumor in her right neck at 29 weeks of gestation and delivered by cesarean section at 37 weeks. Postnatal imaging confirmed a cervical lymphangioma, which was partially removed when she was 34 days old. Post-surgery, she developed ipsilateral Horner's syndrome, causing her hair to turn straight on the affected side. By 2.5 years old, her Horner's syndrome had improved, and her hair texture returned to being curly on both sides.
