What is pseudo tumor kidney?

A renal pseudotumor is a mass that will simulate a tumor on imaging but is composed of non-neoplastic tissue.

How common are benign kidney tumors?

One in four renal masses are benign. Smaller masses are more likely to be benign. Larger masses are more likely to be cancerous. Some tumors can be slow to grow while some can be aggressive.

Are most kidney tumors cancerous?

Although most kidney tumors are malignant and therefore cancerous, up to 20% are benign. Benign tumors do not spread to other parts of the body. Having no signs of spreading is important for deciding what treatments might be best for the tumor.

What are the chances of a kidney tumor being cancerous?

These benign growths include cysts, oncocytomas, angiomyolipomas, and mixed epithelial stromal tumors. Thus, 70-80% of these “small” kidney tumors are cancers and fortunately the majority are “well behaved” (low grade) cancers.

What is Dromedary Hump kidney?

Dromedary hump is a prominent focal bulge on the lateral border of the left kidney caused by splenic impression, which can mimic renal neoplasm. It is a benign anatomic variant and exhibits the same imaging characteristics as adjacent renal cortex with normal blood flow pattern on Doppler sonography.

Can you get pain from a Dromedary Hump?

What causes Dromedary Hump on a kidney?

What kind of tumor is a renal pseudotumor?

Renal pseudotumour. A renal pseudotumour is a mass that will simulate a tumor on imaging but is composed of non-neoplastic tissue.

How are inflammatory pseudotumors different from other cancers?

The propensity of inflammatory pseudotumors to be locally aggressive, to frequently be multifocal, and to progress occasionally to a true malignant tumor supports this idea (, 3 –, 7 ). Immunohistochemical studies of T- and B-cell subpopulations may be helpful in distinguishing inflammatory pseudotumor from lymphoma.

Where does inflammatory pseudotumor occur in the liver?

Inflammatory pseudotumor of the liver has been recognized with increased frequency, mainly in Asian countries (,12 ). The majority of hepatic inflammatory pseudotumors occur in children and young adults. Most cases have been solitary solid tumors, mainly arising from the right hepatic lobe.

When is inflammatory pseudotumor most common in children?

Inflammatory pseudotumor is the most common primary lung mass seen in children, constituting approximately 50% of benign intrapulmonary tumors seen in pediatric patients (, 3,, 4 ). These tumors have no sex predilection, and their peak prevalence is in the second decade of life.
