Imaging features of renal hydatid cyst presenting with hydatiduria

Isolated renal hydatid disease: laparoscopic approach to an uncommon entity (case report)

Hydatidosis is a parasitic disease, endemic in various parts of the World. It frequently involves liver and lungs and, rarely, other organs as well. Isolated renal hydatidosis is a rare entity that accounts for less than 3% of all hydatid cases. Surgery remains the mainstay of treatment. We hereby report a case of isolated renal hydatid cyst involving left kidney that was managed by laparoscopic approach.

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

BACKGROUND

Almost all cases of renal hydatid cysts need surgical intervention for treatment. We report a case of isolated renal hydatid cyst treated successfully only with medical therapy.

CASE PRESENTATION

This case is a 79-year-old veterinarian presented with right flank pain, hydatiduria and positive echinococcus granulosus serology. A 70*50 mm cyst with daughter cysts in mid-portion of right kidney on presentation was changed into a 60*40 mm cyst without daughter cysts at last follow-up. Due to patient's refusal of surgery, our patient received medical treatment including praziquantel and albendazole. After completion of first round of treatment, recurrence occurred and the same treatment was repeated. At last, the cyst became inactive and calcified with negative serology and no clinical symptoms under medical treatment.

CONCLUSION

The treatment of choice in renal hydatid cyst is surgery; although there are some reports about the efficacy of medical treatments for hydatid cysts but lower rates of recurrence and higher efficacy put surgery in a superior position compared to medical approaches. Our case showed relative success of medical treatment, despite the presence of a large multilocular renal involvement. Thus, medical therapy without surgery can be considered in very particular cases with isolated renal hydatid cysts.

Presence of an Isolated Hydatid Cyst in the Left Kidney: Report of a Case of This Rare Condition Managed Surgically

Introduction. Hydatid cyst disease caused by Echinococcus granulosus is rarely presented in the kidneys, whereas isolated renal occurrence is estimated to be about as low as 2–4% of all cases. We present a case of a female patient suffering from this condition that was treated successfully in our department. Case Presentation. A 44-year-old woman was incidentally diagnosed with a 14 cm left renal cystic mass through ultrasound imaging performed during upper abdominal pain investigation. Laboratory examinations were normal and CT imaging set the diagnosis of an isolated left renal hydatid cyst. The cyst was excised and the postoperative period was uneventful. Discussion. Isolated renal hydatid cyst is a very rare condition and could possibly be misdiagnosed with other renal masses. The clinical history, laboratory tests, and thorough radiologic imaging are crucial for the accurate preoperative diagnosis.

Pictorial review: Imaging features of unusual patterns and complications of hydatid disease

Hydatid disease is a worldwide zoonosis produced by the larval stage of the Echinococcus tapeworm. We demonstrate rare locations and unusual complications of this entity during past 6 years. Rare locations during our observation included lumbar spine, sacral spine, spleen, ovary, abdominal wall, diaphragm, pelvis and right kidney. Unusual complications included formation of bronchopulmonary fistula, complete collapse of left lung secondary to hilar location of Hydatid cyst and hydatiduria.
