We are showing a T1W fat suppressed gadolinium enhanced image.
What do you see?
Submaseteric fluid collection, irregular rim enhancement (Abcess)
The masticator space is the primary sit of spread from mandibular infection.
Images of a CT bone window are shown.
What do you see?
1. Mixed lytic and sclerotic lesions of the skull (cotton wool appearance).
2. Widening of the diploic space.
3. Frontal bone enlargement giving the appearance of the Tam o’Shanter hat
23-year-old male:
* Blunt force trauma of the abdomen
* Patient is hemodynamically stable
What do you see?
* Linear zone of hypodensity through the pancreatic body on both phases
* Surrounding fluid with relatively high-density retroperitoneal AND intraperitoneal
Note that the pancreas may appear normal in 20%-40% of patients when CT is performed within 12 h after trauma
MRCP may be useful to evaluate the integrity of the pancreatic duct
* Complete laceration of the pancreatic body: AAST Grade III
* Require surgery within 24h
* Possible complications: fistula, pseudocyst, pancreatitis, abscesses, hemorrhage, pseudo-aneurysm
* Usually, injuries of other organs as well
Treatment in this case: distal pancreatectomy and closing of main pancreatic duct transsection, discharge to hospital in home country after 2 weeks
What do you see in the following images?
Cerebellopontine angle meningioma
* Extra-axial CP angle mass.
* Heterogenous low signal intensity on T2.
* Intense enhancement on post-contrast images with thickening and enhancement of the tentorium cerebelli.
* No intracanalicular extension.
Differential diagnosis: Schwannoma, ependymoma, metastasis
45-year-old male:
* Presenting with mixed hearing loss
What do you see?
Diffuse feneestral and retrofenestral otosclerosis.
45-years-old male:

What do you see?

What do you see?
16-year-old patient with dystonia, mask-like face, rigidity, dysartria.
What do you see?
What do you see on the following images?
* Right frontal lesion with characteristic high T2 popcorn appearance with dark signal rim.
* T1 high signal areas indicating hemorrhage.
* Significant blooming on SWI.
