An exophytic lesion smaller than 3 cm is typically amenable to minimally invasive nephron sparing surgery or ablative therapy, prompting clinicians and patients to commonly opt for treatment but is treatment truly necessary?

Subsequent computed tomography (CT) revealed an exophytic lesion in the lower pole of the left kidney, measuring 36 × 23 × 39 mm, well demarked, with peripheral enhancement, and a central...

Exophytic renal tumors are more likely to be of lower pathologic grade and of the papillary RCC subtype when compared with endophytic renal tumors. A larger prospective study is required to confirm these findings and determine the implications. This information may be useful when small tumors are be …

Axial contrast-enhanced CT image (b) confirms the presence of a low-density nodule in the lower pole of the left kidney that measures −42 HU, diagnostic of gross fat and AML.

A cortical nodule is defined as a focus of more normal renal cortical tissue than usual in an otherwise normal kidney. Such nodules can mimic renal tumors on excretory urography. The urographic features of 29 cases of renal cortical nodules were correlated with arteriographic features to determine i …

A 66-year-old woman with a Bosniak Category IIF cystic mass in the lower pole of the right kidney and prior partial nephrectomy for clear cell renal cell carcinoma. (A) Transverse postcontrast computed tomography (CT) image demonstrates a 1 cm cystic mass (arrow) with few thin septa.

Sep 22, 2024 · Exophytic lesions can occur in various parts of the body and may range from benign cysts to malignant tumors. Imaging plays an important role in the diagnosis and evaluation of these lesions. Ultrasound, CT, MRI, and PET scans each have their strengths in assessing exophytic lesions, and the choice of imaging technique depends on the lesion’s ...

A small fat-containing mass lies in the lower pole of the left kidney, consistent with angiomyolipoma as seen on CT imaging (arrow). Primary renal lipoma is a very rare renal neoplasm with only 20 reported cases in the published literature [ 7 ] .

Jan 2, 2022 · The axial and coronal T2 images show a cystic lesion within the lower pole of the left kidney with a thickened irregular wall. As less than 25% of the lesion is comprised of solid tissue, the lesion should be classified as a cystic mass instead of a cystic solid renal tumor.

Apr 1, 2018 · Atypical cysts are characterized using CT by high attenuation values (≥ +20 HU), the presence of a visible wall, mural nodules or septations, and calcifications. With the exception of calcifications, these morphological criteria can be identified using MRI.
