 House picked up a prescription for pain meds from the hospital pharmacy, supposedly for a patient of Wilson's (it turns out the patient has recently died).Cuddy offers House Vicodin, asking him to come back to help with Abigail's diagnosis, and House refuses Cuddy's drugs, but takes on the case.Abigail is eventually found to have a granuloma pressing against her pituitary gland, evidently causing her apparent "dwarfism", which points to Langerhans cell histiocytosis.
