Also known as: Eye fluid buildup causing vision changes
Initially considered as a diagnosis for the patient's micropsia (seeing things as smaller than normal), linked to type-A personalities, but ruled out after funduscopic exam was normal.
Also known as: Visual distortion syndrome
The patient's initial presentation where he experienced micropsia (things appearing small) followed by macropsia (things appearing large) after waking from a nap. Initially diagnosed as a migraine variant affecting the occipital lobe, but later revealed to be part of a more complex condition.
Also known as: Lung bleeding
Patient developed a hemorrhagic site in the left lower lobe requiring intubation, which led to multiple differential diagnoses including hyperviscosity syndrome and myelodysplastic syndrome.
Also known as: Rapid heart rate
Patient experienced accelerated heart rate and chest tightness initially thought to be a myocardial infarction, leading to cardiac catheterization which showed clean coronary arteries.
Also known as: V-tach
Patient developed V-Tach during echo lab, leading to cardiac catheterization, though coronary arteries were found to be clean, pointing to an electrical rather than plumbing problem.
Also known as: Low oxygen levels
Patient wasn't saturating properly during electrophysiology study, raising concerns about respiratory function despite normal appearing vitals.
Also known as: Persistent vegetative state
Patient went into a coma during the tilt table test, leading to debate between autonomic dysregulation syndrome versus normal pressure hydrocephalus as the underlying cause.
Also known as: Thick blood syndrome
The final diagnosis: patient's blood became thick and syrupy from complexes of large Y-shaped antibodies caused by his rheumatoid arthritis. This clogged blood vessels and caused organs to shut down one by one. Treated with plasmapheresis to filter out the antibodies.
Also known as: RA
Patient's underlying rheumatoid arthritis produced the Y-shaped antibodies that caused his hyperviscosity syndrome. Mentioned early in episode when patient insisted on picking up his own lawn despite his arthritis.
Also known as: End-stage lymphoma
The patient's wife died of non-Hodgkin's lymphoma four months prior to the episode, which influenced his decision to move the company. Mentioned as potentially misdiagnosed and possibly caused by HTLV-1 virus, though this theory was later ruled out.
