“…All of these features are also characteristic findings in both benign mesoblastic nephroma1, 10, 11 and malignant nephroblastoma2, 3 (Table 1). Postnatal imaging of rhabdoid tumors frequently detects tumor necrosis, hematoma or an eccentric crescent with fluid attenuation4, 12. Prenatally we did not observe any of these signs.…”

“…On MRI, the mass is heterogeneous, with intermediate signal intensity on both T1-and T2-weighted images. Subcapsular fluid collection demonstrating high signal on T2-weighted images has been reported in almost half of the cases [14]. Retroperitoneal adenopathy, which is reported in half of the cases of MRTK, usually indicates a poor prognosis [14,15].…”

Congenital mesoblastic nephroma (CMN) can present with atypical clinical and imaging findings. A premature male neonate was born to an 18-year-old woman after 33 weeks' gestation, which was complicated by polyhydramnios and placenta abruptio. A right abdominal mass was diagnosed antenatally. From the 1st day of life, the newborn had hypercalcemia with initially normal parathormone levels and polyuria for the first hours of life and normal urine output afterwards. Ultrasonographic study and magnetic resonance imaging of the abdomen showed at the upper pole of the right kidney a heterogeneous, solid, poorly defined mass, partially surrounded by a subcapsular fluid collection mimicking malignant rhabdoid tumor of the kidney. Surgical resection revealed a CMN of mixed, classic, and in areas, cellular type. One year after the resection, the patient is asymptomatic and normocalcemic. In conclusion, CMN may present with atypical clinical and imaging findings, necessitating an extensive work-up in order to exclude highly malignant renal tumors of the neonatal period.

“…Mainly, MCDK occurs unilaterally and is associated with urinary obstruction (5). In contrast, MRTK is a rare malignant tumor of the kidney, and it accounts for about 2-3% of kidney tumors (3). MRTK also tends to occur in young infants and is one of the most lethal neoplasms in early life (7).…”

“…The size of the tumor is usually greater than 9 cm in diameter. The recurrence rate is high, and the tumor tends to metastasize to the lung, liver, and brain (2, 3). There have been some reports concerning MRTK and MCDK presenting individually and MCDK presenting with Wilms tumor (4).…”

Malignant Rhabdoid Tumor of the Kidney Combined with Multicystic Dysplasia in a 5-year-old Child

Multicystic dysplastic kidney (MCDK) is a relatively common developmental anomaly in infants and children and has a good prognosis. In contrast, a malignant rhabdoid tumor of the kidney (MRTK) is one of the most lethal neoplasms of early life. However, the presentation of such a lethal tumor combined with multicystic dysplasia has not been reported to date. In this report, we describe a case of MRTK in a 5-yr-old girl who also had multicystic dysplasia. She was previously diagnosed with MCDK at birth due to a huge palpable mass on the right side of the abdomen. The right kidney was extensively replaced by numerous grossly dilated, variable-sized cysts. Microscopically, the tumor cells show a diffusely infiltrative growth pattern, which revealed large non-cohesive, round-to-polygonal tumor cells with vesicular nuclei. Some tumor cells had eccentric nuclei and large, round, eosinophilic cytoplasmic inclusions. There were metanephrons present, with the central ureteric bud and peripheral branches surrounded by condensing mesenchyma, immature glomeruli, and metaplastic cartilage in the adjacent parenchyma. To our knowledge, this is the first combined case of the two aforementioned diseases and this case may, in fact, suggest a new disease entity.
