This is the cortical brush sign of cerebral vein thrombosis https://t.co/vhKR6cDFQb

[RADIOLOGISTS @DrAyubaD]

EASY ONE 🔥🔥

Young adult with severe headache, fever, periorbital swelling, proptosis and cranial nerve palsies (III, IV, VI).

Contrast-enhanced CT BRAIN done.

What is the diagnosis?

FINAL ANSWER ;

Ivy Sign in Moyamoya Disease
Diffuse leptomeningeal hyperintensity along the sulci on FLAIR (slow-flow pial collaterals) with corresponding enhancement on post-contrast images.

Classic in children with recurrent TIAs.

NEURO CASE 🔥🔥NEURO ENTHUSIASTS🔥🔥

Child with recurrent transient ischemic attacks and headaches.

MRI Brain (FLAIR axial + post-contrast T1).

What is the name of this classic sign?

What is the diagnosis?

[RADIOLOGISTS @DrAyubaD]

Beautiful illustration of the findings in a patient with congestive cardiac failure .

Findings
1. Cardiomegaly
2. Cephalization or upper lobe diversion
3. Fluid in fissures ( labeled here as effusion)
4. Kerley lines

Enjoy !

1/Do radiologists sound like they are speaking a different language when they talk about MRI?

T1 shortening what? T2 prolongation who?

Here’s a translation w/an introductory thread to MRI.

ADULT EMERGENCY CASE 🔥
A 35-year-old with severe sore throat, high fever, drooling, trismus, neck pain and swelling for 4 days. Difficulty swallowing and voice change.

Contrast-enhanced CT neck done.

Red arrows highlights the lesion.

What is the diagnosis?
Which space is involved?
Why is this a potential airway emergency?

[Jack Garnham @jjgarnham]

Fenestral otospongiosis! Most common cause of progressive conductive hearing loss in young adults. Female predominance (2:1), peaks at 20 – 40, often bilateral and familial. Look for the classic focal lucency at the fissula ante fenestram (just anterior to the oval window).

[C.Alberto Ortega @albertoortegana]

The patient developed cerebral air embolism following CPR.
During cardiopulmonary resuscitation, especially with:
vigorous chest compressions
positive-pressure ventilation
possible lung injury or barotrauma
Air can enter the vascular system (e.g., via damaged alveoli or veins) and travel to the brain.

This week's SPIN POV: Lysosomal disorders - GM1 gangliosidosis, Krabbe's, and Neuronal ceroid lipofuscinosis must be considered when encountering T2 dark thalami and white matter signal change in a child with neuroregression.

This one's for me!!

I was tired of seeing small MCA infarcts that were clearly from a branch occlusion& not knowing the name of the branch that was occluded!

I decided I would find a way to remember these territories myself-and then share it w/ you!!

Here's how you can remember the different territories

Start w/4 cardinal territories
-These are the skeleton from which you can remember the rest

Orbitofrontal: Easy, it overlies orbit in the frontal region, like its name

Central: East, it's the territory surrounding central sulcus

Angular: Easy, it literally looks like an angle between parietal & temporal region

Polar: Easy, it's the temporal pole!

Bc it's the MCA, there is an M or two humps between each of these cardinal branch territories & their names reflect the anatomy

Finally, the temporal territories look like fingers on a hand:

Polar is the thumb of the hand: remember polar sounds pollex which means thumb

Middle temporal is literally the middle finger!!

Now you know the middle cerebral branch territories— so your reports will never be middling!
