Intrarenal supernumerary ovary excised with partial nephrectomy

Intrahepatic ovulation

“…It is unknown whether the infrequency of such occurrences is caused by a low incidence or lack of detection due to nonspecific symptoms or asymptomatic patients ( 2 ). Occurrence of ovarian tissue within the parenchyma of another organ has been reported only twice, with both cases being intrarenal ( 3 , 4 ). Our case marks the first intrahepatic ectopic ovary.…”

An intrarenal supernumerary ovary concurrent with a completely duplicated pelvis and ureter

“…Hartigan et al [5] reported the second case in 2006 where an intrarenal supernumerary ovary presented as a Bosniak class III intrarenal mass in the right upper pole of the kidney that was removed by partial nephrectomy. The third case is presented in this case report (Table 1).…”

“…It apparently arised from an independent ovarian anlage. Although this rare developmental anomaly has been identified in the uterus, bladder, para-aortic area, omentum, mesentery, pelvic cavity, and retroperitoneal soft tissue [2,3], the occurrence of an intrarenal location of this lesion is particularly uncommon with, to the best of our knowledge, only two cases found in published reports [4,5]. As many as 36% of supernumerary ovaries were reported to have been associated with other congenital malformations of the genitourinary system, including agenesis of the kidney and ureter, bladder diverticulum, etc [6].…”

Supernumerary ovary presenting as a paraduodenal duplication cyst

“…Other reported locations include the pelvis, para-aortic, omentum, intrarenal, bladder and colonic mesentery [15,16]. Supernumerary ovaries are often incidentally found, and thus underreported, however they may also be painful, functional, multiple or associated with other congenital malformations of the genitourinary system [12].…”
