Overview

Several cystic diseases can have features of ADPKD namely autosomal recessive polycystic kidney disease (ARPKD, simple renal cysts, autosomal dominant polycystic liver disease, medullary cystic kidney disease and tuberous sclerosis complex.

Differentiating Polycystic kidney disease from other Diseases

Several cystic diseases can have a presentation similar to ADPKD especially given the variability in phenotype and severity. Below is a list of the most common cystic diseases in the differential diagnosis of autosomal dominant polycystic kidney disease:[1]

  • [Disease name] must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as [differential dx1], [differential dx2], and [differential dx3].
  • [Disease name] must be differentiated from [differential dx1], [differential dx2], and [differential dx3].
  • As [disease name] manifests in a variety of clinical forms, differentiation must be established in accordance with the particular subtype. [Subtype name 1] must be differentiated from other diseases that cause [clinical feature 1], such as [differential dx1] and [differential dx2]. In contrast, [subtype name 2] must be differentiated from other diseases that cause [clinical feature 2], such as [differential dx3] and [differential dx4].

-Ascending cholangitis

-Biliary dysgenesis

-Pulmonary hypoplasia in neonates

-Ultrasonography of parents will not show cysts

Simple renal cyst[2] -Negative family history of renal cystic disease

-cortical hemartomas

-white matter lesions

CT kidneys will differentiate cystic and solid lesions, as well as renal angiomyolipomas -Seizures

-Mental retardation

-Angiofibroma (face)

-Renal cysts

-Renal angiomyolipomas

Von Hippel-Lindau disease[4] +/- +/- +/- - + - -Retinal hemangioma

-Clear cell renal cell carcinoma

-Cerebellar and spinal hemangioblastoma

-Pheochromocytoma

-Pancreatic tumor
