Congenital mesoblastic nephroma 50 years after its recognition: A narrative review

“…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 .

Mesoblastic nephroma in an adult: spiral CT appearance

“…Since this first description of mesoblastic nephroma in an adult, eight other cases have been described, with only one prior case in the radiology literature presented in 1982 [5]. An 18-year-old man presented with right upper-quadrant pain, and CT established the renal origin of a large right-flank mass.…”

“…It is usually diagnosed in the first few weeks of life, unlike Wilm's tumor which increases in incidence after three months of age [1]. Mesoblastic nephroma is extremely rare in adults, with only nine reported cases to our knowledge [1][2][3][4][5]. The computed tomographic (CT) description in adults has only been reported on one prior occasion [5].…”

“…Mesoblastic nephroma is extremely rare in adults, with only nine reported cases to our knowledge [1][2][3][4][5]. The computed tomographic (CT) description in adults has only been reported on one prior occasion [5]. We present an additional case of mesoblastic nephroma in an adult, and define its appearance with Spiral CT scanning.…”
