71 y/o make, COVID +, anorectal bleeding. No PSA available.
First thought was prostate abscess...

@danatsouza @LetDdiceFlyHigh @SocietyAbdRad @hiltonmlf @NickSchiedaMD no radiation... i was thinking something like glomerular pathology , but haven't seen any...😂

[Fernando Ide Yamauchi @NandoIde]

14 y/o female, work up for adrenal adenoma (otherwise asymptomatic).
Has anyone seen this pattern of bilateral renal band of high T2WI, no restriction on ADC, slightly hipoperfused?

@mauzappa @LetDdiceFlyHigh congrats @mauzappa !

[Fernando Ide Yamauchi @NandoIde]

@ErickMRemer @SocietyAbdRad @adrenaldfp There are typical adenomas (homogeneous and <10 UH, probably still safe <20UH).
There are clear "take me out" lesions, large and heterogeneous.
And there are "i don't know" lesions, which unfortunately, there's little to improve with other imaging (CT washout / MRI / PET).

[Fernando Ide Yamauchi @NandoIde]

42 yo, LUTS, no PSA available (and unfortunately no answer yet...)
Any thoughts?

@MorbeckFernando @PublioViana @hiltonmlf @pedropanizza3 great talk on prostate imaging!

[Fernando Ide Yamauchi @NandoIde]

@mauzappa @MorbeckFernando @SchuchAlice @lkayat @IvanPedrollo @Felipegaliza @marcelogusmao2 @CassiaTamura @ivpedrosa @NickSchiedaMD nice case @mauzappa ! as we would say in portuguese "without rodeo": inflammatory lesion. 😂
Now you can hit me with the right answer

@coronilRMD @SocietyAbdRad @Felipegaliza @LetDdiceFlyHigh @voxelmator i'll follow @voxelmator , thick walls remind chronic infection. isn't that an excluded upper unit? do we have more coronals?

[Fernando Ide Yamauchi @NandoIde]

@Felipegaliza not sure we are ready, but definitely the way to think of a P5: am I confident enough to skip biopsy? If the answer is yes, that's a P5, otherwise, is P4.

@Felipegaliza @hiltonmlf @PublioViana @LetDdiceFlyHigh @VChernyakMD @mharisinghani @coronilRMD @SamGalgano @cookyscan1 i'll follow @ankushjaj: saponification of peripancreatic fat

[Fernando Ide Yamauchi @NandoIde]

@coronilRMD @lkayat @wroclawski_uro we are at the beginning of this journey, learning from @SchuchAlice , @lkayat and many others.
Urethra is retrograde filled with lidocaine (10-15ml). High resolution T2WI are performed, as well as delayed post contrast sequences. finally, dynamic voiding is acquired

@swoo_rad @epi_rad @SAR_ProstateDFP @radiolobt @Purysko @midrisdoc every time I try to argue this, i get a disapproval from senior colleagues: "if you want to do different from what is stated on the document, than create your own system".
But think about it: weren't we using bosniak on MRI before the updated version?

[Fernando Ide Yamauchi @NandoIde]

@Felipegaliza @ErickMRemer @NickSchiedaMD @swoo_rad @hiltonmlf @PublioViana @LetDdiceFlyHigh @coronilRMD i would probably skip formal bosniak, but use concept: no solid component, no thick septa.
calcification = benign
fat = ?
That's a "no touch" lesion, likely to be followed up.
(could that be a calicial diverticulum?)

[Fernando Ide Yamauchi @NandoIde]

@coronilRMD nice case! chronic hematoma/urinoma? any previous exam to help us?

[Fernando Ide Yamauchi @NandoIde]

@danatsouza @BrighamRad @AURtweet @FOAMrad @SAR_RFS @futureradres @HarvardMacy @CBRadiologia nice case @danatsouza ! no spleen involvement ?

[Fernando Ide Yamauchi @NandoIde]

@TWMU_FATS tell me about it!

[Fernando Ide Yamauchi @NandoIde]

@epi_rad there's an old saying that i love to quote: "the best exam is always the prior exam"

[Fernando Ide Yamauchi @NandoIde]

Just happened to see a similar case here...no history of trauma or pain... 80yo.
Waiting for serum markers, but really favoring a follow up here.

[Jonathan A. Hernández Mancera @JHernandez_RX]

Young patient with right scrotal pain w/o trauma. US shows anechogenic lesion with no Doppler. 2 MRIs 2 months apart show the evolution of a testicular segmentary infarction to a scar. Knowing this pathology could avoid an unnecessary orchiectomy. #radiology #urology
