Plot summary
A mother, Lucille Palmeiro ( Stacy Edwards ), collapses after a blood clot travels from her leg to her heart. After arriving in the hospital, she begins to vomit blood, causing House to expect a Vitamin K deficiency. House's team discover unused Ampicillin and frozen microwave burgers, supporting House's diagnosis. An ultrasound of Lucille's liver reveals cirrhosis and a cancerous tumor. The tumor is too large to resect but House orders the team to shrink the tumor with an injection of ethanol so that the surgeon will operate. They are still unable to explain the cirrhosis.
However, Lucille, in a decision House claims to be inconsistent with her schizophrenia, calls Social Services to take her son. The team consider that Wilson's disease could explain all symptoms and an eye exam shows copper-colored rings around her irises. Lucille receives treatment, is healed, and reunites with her son. Final diagnosis: Vitamin K deficiency, hepatocellular carcinoma, and Wilson's disease
