“…CMN most commonly occurs early in infancy and over 15% of the cases are detected prenatally . Although CMN has been reported in 26 adult patients in literature, it remains uncertain whether these cases are real CMN's . It is believed that most of these so‐called adult mesoblastic nephromas are now recognized to have represented other tumors, such as metanephric stromal tumor, cystic hamartoma of the renal pelvis, or mixed epithelial and stromal tumor .…”

Congenital mesoblastic nephroma (CMN) is a rare pediatric renal tumor with low malignant potential that most commonly occurs early in infancy. Treatment strategies are based on the few published CMN series, while a significant number of CMN patients have been described in case reports. The aim of this narrative review was to create an up-to-date overview of the literature. Complete surgical removal is curative in most cases. The risk of treatment-related mortality (both surgery- and chemotherapy-related) is relatively high in the first weeks of life, indicating that these young patients deserve special attention with respect to timing and type of treatment.

“…Published imaging appearances of these entities are limited to small series and descriptions found only in case reports [23][24][25][26]. Freeby et al [23] and Groves et al [24] described the CT and MRI appearances, respectively, of single cases of adult mesoblastic nephroma. The radiological appearance of both tumours was concordant with our series; both lesions were wellcircumscribed, cystic lesions with solid enhancing components.…”

Study Type – Diagnosis (case series) Level of Evidence 4OBJECTIVETo describe the features on ultrasonography (US), computed tomography (CT) and magnetic resonance imaging (MRI) of mixed epithelial and stromal tumours of the kidney.PATIENTS AND METHODSFive women with renal mixed epithelial and stromal tumours (mean age 55.6 years, range 49–59) who had preoperative imaging were retrospectively analysed. Three ultrasonograms, five contrast‐enhanced CT scans, and one contrast‐enhanced MRI examination were available for review. Specific imaging features analysed included lesion size, location, enhancement and cystic composition. The presence of calcification, septation, nodularity and a capsule were also evaluated.RESULTSAll mixed epithelial and stromal tumours appeared as well‐marginated, multi‐septate cystic masses with a nodular component. All lesions were classified as Bosniak category III (three) or IV (two). The presence of calcification (four) or a capsule (three) was variable. Two tumours invaginated into the renal pelvis with no invasion.CONCLUSIONMixed epithelial and stromal tumours of the kidney have a diverse radiographic appearance, indistinguishable from multilocular cystic nephroma and cystic renal cell carcinoma.

“…The first case of adult mesoblastic nephroma (MN) was described by Block in 1973. [2] Although the findings of the computed tomography (CT) and magnetic resonance imaging (MRI) for MN in adults have been described in sporadic cases,[3] the multiphasic contrast-enhanced CT and MRI features have not been widely reported. We present two additional cases of MN and describe their features on multiphasic contrast-enhanced CT and MRI.…”
