A granuloma (a non-cancerous lesion that contains small abnormal clumps of cells) forms as a result of an inflammatory reaction in body tissues. Granulomas that are found in the liver are associated with inflammation caused by infection (e.g. mycobacterial infection), liver disorders (e.g. primary biliary cholangitis), and noninfectious causes (e.g. sarcoidosis, medication-induced liver injury).
Sometimes there is a finding in an organ that is found in passing and is too small to get a clear view from the scan images. This makes it difficult to provide a diagnosis of the finding. There is an incompletely characterized lesion of the kidney. Usually, this finding is a cyst (pocket of fluid) - a common, benign (non-cancerous) finding.
Abnormal kidney rotation refers to an anatomical variation in the position of the kidneys, in particular to a change in the orientation of the renal hilum. The hilum is the concave part of the bean-shaped kidney where blood vessels, nerves and ureters (the narrow tube urine travels down from the kidneys into the bladder) are located. Before birth, the kidneys normally pass through a complex series of developmental steps when they change position and orientation. Malrotated kidneys occur when these steps do not occur in the usual way. Malrotation of the kidneys may occur with one kidney or both.
A lobular kidney has a surface that does not appear completely continuous. This usually occurs during fetal development when the parts that fuse together to make up the kidney do not completely fuse. Another possible cause is from past damage to the kidney causing scar tissue.
Inclusion cysts are mucus collections that form a sac. Sometimes these cysts can rupture and release blood, known as hemorrhagic cysts. Proteinaceous cyst refers to a cyst with a thicker protein fluid inside. Inclusion cysts can be caused by childbirth or minor physical trauma. They are benign (non-cancerous) and are usually asymptomatic (do not cause symptoms), but sometimes can be the cause of pain or a bothersome feeling of fullness in the vagina.
Gyri are ridges on the surface of the brain. There is a mass effect or compressing/pushing of the adjacent gyri from the arachnoid cyst mentioned above.Potential Cancer
