Toddler faces terminal illness as the world's only known case of rare lung condition

A toddler is the world's only known case of a rare disease causing fluid buildup in her lungs. Doctors have exhausted treatment options. Harleigh Tidd, aged three, was diagnosed with lymphangioleiomyomatosis, chylothorax, and skeletal dysplasia. Her condition involves uncontrollable leakage of lymphatic fluid into her lungs. The family is preparing for her passing, with a palliative care team providing support. They are fundraising for a trip to Disneyland and plan to donate her organs.
