renal hydatid infection

Primary renal
hydatid cyst. A thick-walled cystic lesion (red arrow) is seen arising from lateral cortex of interpolar region of right kidney (yellow arrow). It indents the liver parenchyma and shows few internal non-enhancing membranes (green arrow).

Renal hydatid infection is a very rare manifestation of hydatid disease.

For a general discussion, and for links to other system specific manifestations, please refer to the article on hydatid disease.

Epidemiology

Renal hydatid infection is seen in less than 5% of patients with hydatid disease .

Clinical presentation

Clinical manifestations are variable, and have polymorph symptomatology which is rarely specific . Hydaturia is a pathognomonic sign of renal hydatidosis and results from the rupture of a hydatid cyst into the collecting system .

Pathology

Infection is caused by a parasitic zoonosis with the Echinococcus tapeworm. The kidneys are the most commonly affected urinary organs, but bladder, prostate, seminal vesicles and testis can also be involved .

Radiographic features

Plain radiograph

The plain x-ray may show a soft-tissue mass or a ring-shaped calcification in the renal region.

Excretory urography

May demonstrate caliceal distortion, caliectasis and a non-functioning kidney, possibly caused by the mass effect of cystic lesions.

Ultrasound

May show anechoic lesions with well-defined margins.

CT

CT is more accurate and sensitive ,and shows a unilocular or multilocular cysts with or without peripheral calcifications . CT may also show a detached membrane, a multiloculated cyst with mixed internal density, and daughter cysts with lower density than the maternal matrix .

Treatment and prognosis

The surgical approach remains the treatment of choice; particularly using laparoscopy and the resection should be mostly conservative .
