According to Rose and Rennke, â€œRed cell casts . . . are virtually diagnostic of some form of glomerulonephritis or vasculitis.â€ RBC casts are most often associated with diseases that affect the glomerulus, such as acute poststreptococcal glomerulonephtitis and other acute glomerulonephritides, IgA nephropathy, and lupus nephritis.
So, I think the answer is B
e.membranous glomerulopathy because this is nephrotic syndrome where we see massive proteinuria and not RBC casts
d is nephrotic (proteinuria). Others are nephritic (hematuria/ RBC casts)
RBC casts = glomerulonephritis
WBC casts = Pyelonephritis or tubulointerstial nephritis
Fatty casts -= nephrotic syndrome
Wax (broad) casts :Chronic renal failure
Renal tubular cell casts = ATN
RBC casts are indication of glomerular injury due to nephritic syndrome and the The two classic diagnoses of nephritic syndrome are:
* post-streptococcal glomerulonephritis
* crescentic glomerulonephritis
So I guess its B).
The correct answer is d.Membranous Glomerulopathy
Very interesting ,
This post belongs to 3 years ago , when I just started my clinical rotations .OLD TIMES
Those who got it wrong, pls read the question carefully.. It asks which one is the least likely diagnosis.. I hate it when i get questions wrong (inspite of knowing it) just 'cos the language was twisted..
Good thing is, they dont put questions like that on USMLE..
