What is hypodense lesion in kidney?

Abstract. Small hypodense renal lesions with a round shape are frequently detected on CT scans of the upper abdomen after contrast medium administration. In nearly all cases these round hypodensities are simple small cysts with no clinical significance.

Are Exophytic lesions cancerous?

Benign tumors such as a hepatic cyst, hemangioma, hepatic adenoma, focal nodular hyperplasia, and angiomyolipoma and malignant tumors such as a hepatocellular carcinoma, cholangiocellular carcinoma, and metastases may show exophytic growth.

Does a lesion on the kidney mean cancer?

How big are renal cysts in hyperdense patients?

The mean size of 90 hyperdense renal lesions in 79 patients was 1.6 cm (range, 0.5–4.9 cm). In total, 47 cystic lesions (25 haemorrhagic cysts and 22 simple cysts) and 43 solid lesions (24 RCCs and 19 AMLs) were analyzed.

How are hyperdense renal lesions evaluated in Bir publications?

To investigate the utility of dual-energy CT (DECT) for differentiating between solid and benign cystic lesions presenting as hyperdense renal lesions incidentally detected on single-phase post-contrast CT. 90 hyperdense renal lesions incidentally detected on single-phase post-contrast CT were evaluated with follow-up DECT.

What causes a lesion on the kidney tissue?
