Patient	Age (years)	Sex	Clinical picture	Chest x ray	CT chest	Bone marrow	Protein studies	Cardiac studies	Neurological findings	Survival (years)
LUL, left upper lobe; RUL, right upper lobe; RML, right middle lobe; RLL, right lower lobe; LLL, left lower lobe; CT, computed tomography; ECG, electrocardiogram; echo, echocardiogram; LVEF, left ventricular ejection fraction; LVH, left ventricular hypertrophy; PVCs, premature ventricular contractions; MR, mitral regurgitation; TR, tricuspid regurgitation.
