Discussion (Related Text)

OHydatid disease is an endemic parasitic disease with world wide distribution.hunman is an accidental intermediate host due to ingestion of fertilized eggs. The larvae penetrate the intestine to enter the blood stream and lymphatics and travel to the liver, lungs and other organs .Juxtavesical and retrovesical location of the cyst are unusual, but location in the retro-peritoneum is especially rare. The vast majority of abdominal and pelvic cysts are considered to be secondary to prior hepatic localization followed by spontaneous fissuring or rupture. The primary cyst might then heal and even disappear, leaving behind a scar that could be overlooked by any diagnostic modality. Retrovesical and retroperitoneal hydatid cyst disease grows slowly over years and the patient presents with lump in the abdomen and symptoms due to compression of the adjacent structures, usually with chronic renal failure (CRF) due to bladder outlet obstruction. In computerized tomography(CT) Fluid density cyst, with frequent peripheral focal areas of calcification. Septation and daughter cysts may be visualised. Fluid is of variable density depending on the amount of proteinacous debris. May also show hyperdense internal septa representing a spoke wheel pattern within a cyst.
