What does Oncocytoma mean?
What does Oncocytoma mean?
Oncocytoma is a benign solid tumor that arises from the proximal renal tubule. Most are seen in men in their 60s. Unfortunately, no imaging test can reliably differentiate these benign tumors from RCC. Treatment is surgical.
What is an oncocytoma of the kidney?
Renal oncocytoma is a benign (noncancerous) growth of the kidney. They generally do not cause any signs or symptoms and are often discovered incidentally (by chance) while a person is undergoing diagnostic imaging for other conditions.
How common is Oncocytoma?
Renal oncocytomas are common benign kidney neoplasms that account for 3 to 7 percent of renal neoplasms. They usually occur in adults, most frequently in the seventh decade of life. Renal oncocytomas may be discovered incidentally or may be diagnosed with biopsy or excision.
Can oncocytoma become malignant?
Renal oncocytoma is a type of kidney tumor that is typically not cancerous but may have the ability to become malignant. The samples were characterized based on chromosome loss.
How is oncocytoma treated?
Treatment. Renal oncocytoma is considered benign, cured by nephrectomy. There are some familial cases in which these tumors are multicentric rather than solitary. However, they may be resected to exclude a malignant tumor, e.g. renal cell carcinoma.
Do patients referred to PET/CT with contrast undergo CT scans without contrast?
Then, 19 patients referred to PET/CT with IV contrast underwent CT scans without, and then with contrast agent, followed by an 18F-fluorodeoxyglucose whole-body PET scan. The CT examinations were performed with identical parameters on a GE Discovery LS scanner.
What does An oncocytoma look like on a CT scan?
This CT scan shows a well-defined, exophytic, solid mass from the midpole of the left kidney. The mass has an atypical appearance of an oncocytoma, is less attenuating than the renal parenchyma, and does not show a scar. Oncocytomas are well encapsulated and have distinct margins, a smooth contour, and a homogeneous appearance.
Can IV contrast be used for pet attenuation correction in cancer patients?
PET/CT with intravenous contrast can be used for PET attenuation correction in cancer patients This study demonstrates that CT scans with IV contrast agent can be used for attenuation correction of the PET data in combined modality PET/CT scanning, without changing the clinical diagnostic interpretation.
When is iodinated IV contrast used for CT scan?
Iodinated intravenous (IV) contrast is only used when the requesting physician asks for CT scan with IV contrast in addition to the PET/CT. If your doctor requested additional CT scan with IV contrast and you have a history of allergic reaction to iodinated contrast, then you must be premedicated before the IV contrast portion of the scan.
