Autosomal dominant polycystic kidney disease

Case contributed by Mohammad Taghi Niknejad
Diagnosis certain

Presentation

Work up for cough and abdominopelvic pain. Known and operated case of gastric cancer.

Patient Data

Age: 55 Years
Gender: Male

Both kidneys are enlarged and contain multiple varying sized cysts less than 90 mm. In addition, several small cysts are present at the liver less than 15 mm. Features are consistent with autosomal dominant polycystic kidney disease.

The hepatic attenuation value is less than the spleen, suggesting fatty liver.

Postoperative changes are seen due to total gastrectomy and esophagojejunostomy. There is no sign of local tumoral recurrence at the anastomotic site.

Air space opacity is present at the left lower lobe, most consistent with pneumonia.

Mild pleural effusion is present bilaterally.

Cardiomegaly is present, and the pulmonary artery trunk is dilated.

Case Discussion

Autosomal dominant polycystic kidney disease in a known and operated case of gastric cancer.

Notice that there is no increased risk for renal cell carcinoma (RCC) unless the patient is undergoing prolonged dialysis, unlike in some other congenital cystic kidney diseases.
