“…Following abstract screening, 102 articles were determined to be outside the scope of the investigation and a further 14 full-text articles described cases of abdominal tumours without concomitant polyhydramnios. The remaining 27 publications describing 32 cases constituted the basis of this review ( Supplementary Table S1 ), [ 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ].…”

Polyhydramnios represents a complication found in 0.2–2% of pregnancies, and it is usually diagnosed between 31 and 36 weeks of pregnancy. Although most cases of polyhydramnios are idiopathic, maternal diabetes or foetal malformations constitute frequent causes of the excessive accumulation of the amniotic fluid. Considering the latter, polyhydramnios may rarely be caused by foetal abdominal tumours, with the incidence rate of 2–14 cases per 100,000 live births. Congenital neonatal leukaemia (CNL) is a rare disease with a reported incidence rate of 5–8.6 cases per million live births. In the prenatal period, the ultrasound abnormalities associated with CNL include hepatomegaly and splenomegaly. In this paper, we presented a case of polyhydramnios caused by mechanical pressure on the foetal gastrointestinal tract by an enlarged lymph node in the course of CNL, as well as reviewing the available literature on foetal abdominal tumours with concurrent polyhydramnios.

“…The most common fetal renal tumor is the mesoblastic nephroma, which is a benign mesenchymal tumor that appears as a solid or partially cystic tumor, with ill-defined margins due to the absence of capsule, associated with polyhydramnios on ultrasound examination and generally has a good prognosis. 8 The second most common is Wilms' tumor, a malignant tumor in which the kidney may be partly or totally replaced by a mass with increased vascularity on color Doppler. Nephroblastomas are capsulated tumors, characterized by multiple benign nodular lesions and bilateral involvement.…”

Rhabdoid tumors of the kidney are highly lethal malignancies of infancy. We report the prenatal detection of this renal tumor in a fetus in the third trimester of pregnancy. Ultrasonologically, the tumor appeared as a large mass in the left renal area associated with severe polyhydramnios. Though the sonographic features alone did not allow distinction from a benign lesion, tumor extension into the subcutaneous plane favored the possibility of a malignant renal tumor and this was confirmed postnatally on histopathology.

“…Patients older than 3 months at diagnosis with stage III, cellular or mixed subtype, or incomplete resection are more likely to experience recurrence and metastases 3 , 10 , 11 . Adjuvant chemotherapy is advised for such conditions 12 . Postoperative complications include bowel occlusion and enterocutaneous fistula.…”

Background: Congenital mesoblastic nephroma is the most common renal tumor in children under the age of six months, comprising 3-10% of all kidney tumors in children. It is a rare and mostly benign tumor. It divides into cellular, classic, and mixed subtypes. It is typically detected in the third trimester of pregnancy using ultrasonography and magnetic resonance imaging. The best treatment is surgically by completely removing the tumor. Case Presentation: We reported a case of a one-day-old female who was born at 31 weeks gestation weighing 1670 grams. Preterm labor was due to polyhydramnios, which was diagnosed pre-delivery. A large mass was detected in the left hypochondrium using computerized tomography, total nephrectomy was performed, and the histopathological examination of the specimen confirmed the diagnosis of congenital mesoblastic nephroma. Clinical Discussion and Conclusion: Early polyhydramnios could be the most significant sign of renal tumors in infants, especially Congenital mesoblastic nephroma.
