Also known as: Behcet's syndrome
Initial diagnosis for Kayla's joint pain, stomach pain, and uveitis. The team suspects vasculitis affecting blood vessels. Diagnosis is confirmed by positive pathergy test but later complications reveal this was not the complete picture.
Also known as: Stomach ulcer
Kayla develops bleeding ulcers (initially attributed to Behcet's or NSAID use) that perforate, leading to sepsis and cascade of organ damage. This is the central medical crisis that drives the episode's malpractice case.
Also known as: Blood infection
Develops after perforated ulcer spills stomach contents into body cavity. Streptococcus infection confirmed on culture. Sepsis causes severe hypotension leading to blood clots and multi-organ damage.
Also known as: Liver artery clot
Sepsis-induced hypotension causes blood clots to form in hepatic artery, cutting off blood flow and causing liver to fail. Requires liver transplant.
Also known as: Liver failure
Result of hepatic artery thrombosis. Kayla requires emergency liver transplant listing and receives live-donor transplant from her brother Sam.
Also known as: Liver inflammation
Sam has undiagnosed chronic hepatitis C from a home tattoo, which he conceals by bribing lab tech. The chronic infection leads to liver cancer that gets transplanted into Kayla.
Also known as: Liver cancer
Sam has undiagnosed liver cancer secondary to hepatitis C. The hepatoma is unknowingly transplanted into Kayla with the donor liver and grows faster due to immunosuppression. House diagnoses it based on elevated hematocrit. Ultimately proves fatal for Kayla but is caught early enough to save Sam.
Also known as: IPF
Patient House initially tells has fatal lung disease with no treatment. House later reveals it's actually just a cold, using the fake diagnosis to help patient get health insurance before a real diagnosis.
Also known as: Cold
Chuck's actual diagnosis after House misleads him about having pulmonary fibrosis. Used to illustrate House's manipulation tactics.
Also known as: Kidney failure
Develops secondary to sepsis and hypotension. Less severe than liver damage and shown to be healing.
Also known as: Eye inflammation
Inflammation of iris discovered during initial workup. This unusual finding combined with joint pain leads House to suspect vasculitis (Behcet's disease).
