Presentation
Work up for abdominal pain.
Patient Data
Multiple non-enhanced simple cortical cysts are seen at both kidneys, with maximum diameters of 22 mm. Regarding the patient's age, features are most compatible with early stage autosomal dominant polycystic kidney disease.
A 60×35 mm thick walled cystic lesion at the left liver lobe extends to the left subdiaphragmatic space; shows partial marginal calcification. After contrast media injection, no prominent enhancing soft tissue component is present, most consistent with hydatid cyst. In addition, a 30×22 mm non-enhanced cystic lesion without calcification is observed at segment V of the liver. The patient had positive serology for hydatid cyst.
Case Discussion
Features on CT scan are most consistent with the early stage of autosomal dominant polycystic kidney disease, which is a common hereditary form of adult cystic renal disease and by far the most common hereditary cause of end stage renal failure.
