Overview
Although ultrasonography is the modality of choice for diagnosing ADPKD mainly due to the low cost and lack of radiation exposure, computed tomography and magnetic resonance imaging have higher resolutions and increased sensitivity for renal cysts less than 1 cm in diameter. Findings on CT scan include, numerous renal cysts of varying size and shape with little intervening parenchyma with water attenuation and very thin wall, reduction in sinus fat due to expansion of the cortex, occasional complex cysts with hyperdense appearance, with possible septations or calcifications, multiple homogeneous and hypoattenuating cystic lesions in the liver in patients with liver involvement.
CT scan
Renal CT scan may be helpful in the diagnosis of polycystic kidney disease. Findings on CT scan diagnostic of ADPKD include:
- Numerous renal cysts of varying size and shape with little intervening parenchyma with water attenuation and very thin wall.[1]
- Reduction in sinus fat due to expansion of the cortex [1]
- Occasional complex cysts with hyperdense appearance, with possible septations or calcifications [2]
- Multiple homogeneous and hypoattenuating cystic lesions in the liver in patients with liver involvement [3]
Note: Although ultrasonography is the modality of choice for diagnosing ADPKD mainly due to the low cost and lack of radiation exposure, computed tomography and magnetic resonance imaging have higher resolutions and increased sensitivity for renal cysts less than 1 cm in diameter. PET/CT has also been used to confirm and locate cyst infections with varying degrees of success.[4]
