“…Its non-invasive nature and extremely high diagnostic yield ultimately makes it an integral component of uroradiological diagnosis. [5] It is more accurate in delineating a renal mass and in differentiating between a pseudomass and a normal anatomic variant from a tumour and allows studies in patients who have dense renal calcification or in whom USG is technically difficult. It should be used in many areas for definite evaluation of lesions suspected from other studies, for example IVU or USG.…”

“…To determine the cause of the hematuria, the patient was assessed. The preferred diagnostic modality is the ultrasound since there is no risk of radiation to the developing fetus (9). Ultrasound findings showed an isoechoic to mildly echogenic well-marginated mass measuring 39 × 33 mm in the upper portion of the right kidney; the mass caused a bulge on the renal capsule of the upper pole of the right kidney.…”

“…There was also a small cortical cyst with high echogenic content measuring 4 mm in the mid portion of the left kidney. The downside of ultrasound modality is that it is operator-dependent; therefore, full classification and the diagnosis of the renal mass would be suboptimal (9). Radiological contrast agents should be avoided because of teratogenicity effects and transplacental risk for the fetus (13).…”

Introduction: Renomedullary interstitial cell tumor (RICT), or medullary fibroma, is a small tumor that is usually asymptomatic unless it attains a significant size; in rare cases, the tumor may be large and symptomatic. These benign tumors have a specific histology. Although they are usually incidental findings, it is necessary to be able to discriminate this lesion from other malignancies of the kidney, especially since its management represents a challenge during pregnancy. Numerous patients undergo an unnecessary radical nephrectomy to diagnose renal masses, which is considered hazardous for pregnant women. Ultrasound is the imaging procedure of choice followed by the magnetic resonance imaging (MRI) for assessing the urinary system in pregnant women. Histopathological examination is considered mandatory for the diagnosis of RICT to preclude an unnecessary nephrectomy. Case Presentation: In November 2015, a 31-year-old pregnant woman at gestational week 12 of her second pregnancy was referred to our private clinic in Rasht, Iran. She had microscopic hematuria; a mass measuring 39 × 33 mm in the upper portion of her right kidney was was detected by ultrasonography. Conclusions: A percutaneous renal mass biopsy was used, instead of nephrectomy, to diagnose the mass; immunohistochemical reports showed that the morphologic features were not compatible with an epithelial neoplasm and the paucicellular spindle cell tumor was compatible with renomedullary interstitial cell tumor. Patients with RICT can be successfully managed using a percutaneous renal mass biopsy and avoiding unnecessary nephrectomy.

“…10 CT has proved to be an extremely accurate method of differentiating a renal cyst from a neoplasm based on (a) attenuation value of the mass and whether it increased on giving intravenous contrast (b) demarcation of the mass from the normal renal parenchyma and (c) the thickness of the wall of the mass. 11 CT had become an essential imaging tool for the evaluation of the kidney and perirenal space as…”
