What is a cystic Nephroma?
Multilocular cystic nephroma is a benign mixed mesenchymal and epithelial neoplasm of the kidney and is classically described as a benign slow-growing renal tumor. Patients who have multilocular cystic nephroma present with palpable mass, abdominal pain, and hematuria, as in renal cell carcinoma.
What is Mesoblastic Nephroma?
Mesoblastic nephroma (also called fetal renal hamartoma) is the most common renal tumor identified in the neonatal period and the most frequent benign renal tumor in childhood. It represents 3-10% of all pediatric renal tumors. This tumor was first described as a separate entity by Bolande et al in 1967.
What is Multilocular cyst?
Benign multilocular cyst is a rare benign multicystic renal tumor. It usually involves the kidneys unilaterally. There is no generally accepted theory concerning its pathogenesis.
What is a multilocular cystic Nephroma?
Multilocular cystic nephroma (MLCN) is a benign mixed mesenchymal and epithelial neoplasm of the kidney . MLCN is classically described as a benign slow-growing renal tumor, and there are more than 200 cases reported in the literature.
What is a Ptotic kidney?
Nephroptosis, also known as floating kidney and renal ptosis, is a condition in which the kidney descends more than 2 vertebral bodies (or >5 cm) during a position change from supine to upright.
What causes mesoblastic nephroma?
Congenital mesoblastic nephroma is a rare renal tumor that is diagnosed during pregnancy and is associated with polyhydramnios, prematurity, and neonatal hypertension. Differential diagnoses include Wilms tumor, adrenal neuroblastoma, and other abdominal tumors.
What does Mesoblastic mean?
: relating to, derived from, or made up of mesoblast.
Can an ultrasound tell the difference between a cyst and a tumor?
Ultrasound is also a good way to tell fluid-filled cysts from solid tumors because they make very different echo patterns. It’s useful in some situations because it can usually be done quickly and doesn’t expose people to radiation. Ultrasound images are not as detailed as those from CT or MRI scans.
What is the meaning of Multilocular?
: having or divided into many small chambers or vesicles a multilocular cyst.
Who discovered Wilms?
Wilms tumor is typically found in children younger than five years old. The tumor is named after the German physician, Dr. Max Wilms, who first described it in 1899.
What causes Ptotic kidney?
Some doctors believe that nephroptosis may be caused in part by any event that weakens the ligaments that hold the kidney in place within the body. These events could include any of the following: sudden, dramatic weight loss. pregnancy and childbirth.
How is radiography used to diagnose cystic nephroma?
However, the use of radiography to diagnose multilocular cystic nephroma specifically results in a low degree of confidence. On plain radiographs, multilocular cystic renal tumor appears similar to other renal tumors because plain radiography cannot be used to differentiate between cystic and solid lesions.
What’s the difference between cystic nephroma and CPDN?
Cystic nephroma and CPDN are indistinguishable from one another based on their gross and radiographic appearances (, 3) and can be lumped under the term multilocular cystic renal tumor (MCRT) (, 4 ). MCRT was first described in the late 19th century as cystic adenoma.
What kind of tumor is multilocular cystic nephroma?
Furthermore, they proposed that both terms be used as subsets of the category term multilocular cystic renal tumor. Multilocular cystic nephroma is a benign mixed mesenchymal and epithelial neoplasm of the kidney and is classically described as a benign slow-growing renal tumor.
Is the DICER1 gene mutation associated with cystic nephromas?
Cystic nephromas, previously known as multilocular cystic nephromas, are rare benign renal neoplasms classically occurring in adult females in the 4 th and 5 th decades. As of the 2016 WHO classification, they are considered distinct from pediatric cystic nephromas which have associated DICER1 gene mutation 10,11,14.
