0 Cerebral sinus thrombus



This is an example of a question which can be solved with Presence of Mind alone. And proves that Knowledge is not necessarily required sometimes.


Q. Cerebral sinus thrombus, true are All Except ?

a. Dense delta sign on NCCT

b. Cord sign on NCCT

c. empty delta sign on contrast CT

d. empty delta sign on NCCT



ANSWER:
Option C and D are opposite of each other --- Thus one of them is True and one is false.
This means that the other two are True as the question asks All Except
Now as Option A is True so , Option D which is opposite of Option A , must be wrong... Thus the answer is Option D. :)
Medical explanation :
In contrast CT , the area where there is a thrombus will not let the contrast fill (filling defect) - hence seen as empty.
In Non contrast CT - this thrombus is seen as bright (hyperdense) - hence Dense delta sign.



4 Neiman pick , Tay Sach , Hunter's




This story is about a boy called Niemann who was fond of fried foods

one fine morning, he decided to have cherries fried in oil for lunch

so he set out to pick cherries from the lawn. he went riding on his pet zebra


he reached the garden & started picking up cherries



while our dude Neiman was busy picking up cherries,
he was being watched by
a old hunter

The hunter wanted to steal the zebra


But

Another boy
TaySach was in the garden picking up onions


Tay sach was a brave boy

he scared away the hunter


neiman was happy on seeing this
& befriended taysachs
as a token of friendship, he gifted taysach cherries & oil for a great lunch


he also gave taysach a ride on his zebra back home


moral of this weird story

*cherry red spot
*staining with oil red o


tay sach dis
*zebra bodies
*cherry red spot
*staining with oil red o
*onion ring deposits in skin


hunter disease

1. They're all autosomal recessive, with the exception of Fabry's and Hunter's, which are both X-linked recessive.

2. Hurler and Hunter's both start with an H, and both accumulateHeparan sulfate. (Hopefully that will help you remember that they accumulate dermatan sulfate too).

3. Ashkenazi Jews have a higher risk of Gaucher's, Niemann-Pick, and Tay-Sachs.

4. Gaucher's spares the Brain., has crummpled tissue paper appearance.

5. Remember: "globoid cells" = Krabbe's.

6. "Cherry-Red" (spot on macula) is hyphenated. So are "Niemann-Pick" and "Tay-Sachs." :)

7. Hunters is X-linked. I view a Hunter shooting his bow at a X (target).

8. Niemann-Picks - Sphingomyelinase. No man picks is nose with is Sphinger (finger).

9. As above regarding Hunter's vs Hurlers. Hurlers you get corneal clouding, so you cannot be a good hunter.

10. HurLer's is alpha-L-iduronidase. Hunters, which is a similar disease, is the other one (iduronate sulfatase). "I just remember one, then know that the other one is the other one."

11. Metachromatic Leukodystrophy : Arysulfatase A deficiency
