Also known as: AVM
An intradural arteriovenous malformation compressing the spine is revealed as the true cause of John Henry's paralysis. It was hidden behind inflammation on initial imaging and became visible after steroids reduced the swelling. Surgical removal promises to restore his ability to walk.
John Henry presents with lobar pneumonia causing respiratory distress and low oxygen saturation. This is the initial admission diagnosis that leads to discovery of his underlying paralysis condition.
Also known as: Blood clot in brain
A blood clot lodges in John Henry's brain causing new-onset arm paralysis, separate from his leg paralysis. Successfully treated with embolectomy (surgical clot removal), restoring arm function.
Also known as: ALS, Lou Gehrig's disease
Initially diagnosed by Dr. Hamilton as the cause of John Henry's two-year progressive paralysis. House challenges this diagnosis of exclusion, ultimately proving it wrong when the AVM is discovered. The misdiagnosis had led John Henry to sign a DNR and accept his fate.
Also known as: Diabetes
House diagnoses a clinic patient with diabetes based on hair loss on hands (nerve damage), ill-fitting shoes (loss of foot sensation), and powdered sugar on pants. The patient had failed to disclose his diabetes and was requesting erectile dysfunction medication.
