Accepted Answer

Hyperdense cyst: On noncontrast CT scans, most simple kidney cysts look very dark or hypodense because the fluid inside of them is just like water.  A hyperdense cyst looks much lighter or brighter compared to the kidney itself.  This usually just means that there is high protein in the cyst or that the cyst has bled at some point.

Question 4

what exactly is a renal cyst?

Accepted Answer

Fluid filled cavity: Kidney cysts are formed by blockage of a minute kidney tubule called a nephron. We have about a million nephrons in each normal kidney. Simple kidney cysts are very common and present in about one third of people and are benign. Polycystic kidneys have cysts throughout the organ, are usually present on both sides and are an inherited congenital condition. Rare complex cysts can be cancerous.

Question 5

what does simple renal cyst means?

Accepted Answer

Benign: Simple renal cyst is like a thin balloon filled with clear fluid. Totally harmless if not causing pain. Very common. Not to worry. If it is a "complex cyst" it needs to be followed.

Question 6

what is small renal cyst, bilateral?

Accepted Answer

Cysts: Renal cysts are small collections of fluid in the kidneys.  They occur quite frequently in people and are often only discovered when doing a routine exam for another reason.  Most renal cysts do not have any medical significance but it would be reasonable to discuss with doctor.

Question 7

can you tell me about renal cyst and related problems ?

Accepted Answer

A simple cyst is OK!: A simple (clear or see through) renal cyst is not a significant event. However, a complex cyst, (the one that appears to house tissue or clotted blood inside) is important to follow closely because it may be cancerous. However, if cysts are too numerous and on both sides, like in the case of polycystic kidney disease, the squished renal tissue over the years may lead to kidney failure.

Question 8

what is difference from renal cyst and compartmentalized renal cyst?

Accepted Answer

Septation: Renal cysts can be simple (one cavity and one capsule) or septated or having compartments. Those are complex cysts and some of them may have a higher chance of being or turning malignant than simple cysts. Those complex cysts need to be monitored and may need to be biopsied.
