Parapelvic renal cyst
R. Krasteva

Abstract.

Parapelvic renal cysts are relatively common finding on sonography, CT, MRI. These cysts are more common in patients with Fabry disease. Their size can be up to 50 mm. Parapelvic renal cysts may be asymptomatic and can cause back pain, obsruction, hypertension, pyelonephritis.The differentiation from other pathologic conditions is important – tumors, lipomatosis. Parapelvic cysts often have the picture of hydronephrosis. It is easy to distinguish cyst from varices, renal artery aneurism, arteriovenous fistula by color and pulse Doppler ultrasonogpraphy. The diagnosis should not be based by ultrasonography only so that other pathology should not be missed.

Key words: PARAPELVIC RENAL CYSTS. HYDRONEPHROSIS. ULTRASONOGRAPHY. FABRY. CT. MRI
