Primary renal echinococcosis

Abstract

Echinococcosis is a parasitic infection caused by the larval stage of a cestode Echinococcus granulosus and is endemic in sheep farming regions of developing countries. It manifests as hydatid cyst and most commonly is found in liver followed by lungs. Renal hydatid cyst is rare and amounts for 2% of all cases. There are no specific clinical manifestations, and hence diagnosis of renal hydatid disease is missed out easily without imaging. We report a case of 50-year-old female who had 6 months history of lower abdominal pain with hematuria, found to have right renal hydatid cyst on imaging which was treated with right nephrectomy with pre- and post-operative albendazole treatment.

Medical treatment for an isolated renal multilocular hydatid cyst in an elderly: a case report

“…The cyst may become large enough to destroy the tissues of the host. Renal hydatid cyst is rare and accounts for 2% of all hydatid cyst cases [12].…”

“…In this case abdominal pain was reported but in our case, flank pain was notable. She had right renal hydatid cyst on imaging which was treated with right nephrectomy and albendazole treatment regimen before and after operation [ 12 ]. Kumar et al [ 18 ] reported a 37-year-old female patient with right iliac fossa pain.…”

Renal hydatid cyst presenting as an intrarenal-pelvic mass

“…Isolated intra-renal-pelvic hydatid cyst possibly develops when a small renal parenchymal hydatid cyst communicates with the pelvicalyceal system and subsequently grows within the pelvicalyceal system. [ 5 ]…”

“…On USG, renal hydatid cysts have variable appearance presenting either as unilocular cysts, multiseptated cysts or calcified cysts. [ 1 5 ]…”

“…Typical CT findings of renal hydatid disease includes a unilocular cyst or a multilocular cyst with mixed internal attenuation or daughter cysts with lower attenuation than that of the maternal matrix or a calcified cyst. [ 1 2 5 ]…”
