Kto nezažil, nepochopí...! Kto nepochopí, neprežije. Základnou ľudskou slabosťou je, že človek nepredvída búrku, keď je pekné počasie.

Peripelvic cysts, particularly on ultrasound may mimic a hydronephrosis. CT helps delinate further, especially if a CT-IVU study is performed - contrast filling the collecting system, but not the cyst. Read more on hydronephrosis: http://radiopaedia.org/articles/hydronephrosis

Kidney cyst is a fluid-filled sac that can be found in one or two kidneys. Parapelvic cyst, also called peripelvic cyst, rises from the renal sinus, the outmost inside region of the kidneys.

Subdural haemorrhage (SDH) is a collection of blood between the dura and the arachnoid layers of the meninges. They are common (15% of all head injuries) and can occur in any age range. Over time, these collections can resolve and leave few products behind with a hypodense area on scans (similar to CSF). http://radiopaedia.org/articles/subdural-haemorrhage

Subdural (acute on chronic)

CT scan through the brain of an elderly patient demonstrates a subdural haemorrhage with acute and chronic components. Note how the acute blood sinks inferiorly (haematocrit effect). A similar appearance can rarely be seen in acute haemorrhage in.

White cerebellum sign (also called reversal sign or dense cerebellum sign) is encountered when there is a diffuse decrease in density of the supratentorial brain parenchyma, with relatively increased attenuation of the thalami, brainstem and cerebellum. This sign indicates irreversible brain damage and has a very poor prognosis, which is why radiologists must be aware of this sign. http://radiopaedia.org/articles/white-cerebellum-sign

This case demonstrates many features of global hypoxic-ischaemic brain injury: pseudosubarachnoid haemorrhage white cerebellum sign cerebral herniation

Insular ribbon sign - refers to loss of the normal insular cortex grey-white differentiation and is one of the earliest imaging signs of middle cerebral artery territory infarction. The insular cortex is located along the Sylvian fissure overlying the external capsule where a ‘ribbon’ of normal cortex should be appreciable (red arrows). In the setting of MCA infarction, cytotoxic oedema leads to hypoattenuation such that the normal insular ribbon is no longer visible (blue arrows).

Hepatic Veins - Liver congestion by right-sided heart failure – We find dialted peripheral hepatic veins over 6mm or > 10 mm 2cm before entrance of IVC - We can sometimes find fluid in pleural cavity above the diaphragm.
