Primary mediastinal hydatid cysts

Hydatid cyst at unusual locations: Report of three cases

INTRODUCTION

Hydatidosis is an anthropozoonosis due to the development in humans of the larval form of Echinococcus granulosus and is endemic in many countries of the Mediterranean region such as Morocco.

CASES PRESENTATION

We report three cases of hydatid cyst at unusual locations such as the peritoneum, and the retroperitoneum.

DISCUSSION

Hydatid disease usually involves the liver (75 %), the lungs (15.4 %), and the spleen (5.1 %). Almost any anatomic location can be the host site of the parasitic cysts.

CONCLUSION

Multiple locations of hydatid cyst often pose a problem of differential diagnosis. Surgery is the mainstay of treatment.

Spleen-preserving surgery for splenic hydatid cyst: a case report

Hydatidosis is a zoonosis due to the development of the larval form of Echinococcus granulosus in humans. This disease is very frequent in many countries of North Africa such as Morocco. The most frequent locations of hydatid cysts are the liver (75%) and the lungs (15.4%). Splenic hydatid cyst occurs in only 5.1% of cases. The diagnosis remains challenging and is made upon a hundle of clinical, radiological, biological, and histological arguments. In this paper, we report a case of spleen-preserving surgery for a splenic hydatid cyst to suggest the best management of these hydatid cysts and avoid recurrences.

A rare case of pancreatic head hydatid cyst

Hydatidosis or Echinococcosis is a parasitic disease caused by infection with the larval stage of Echinococcus granulosus. Primary isolated pancreatic hydatidosis is very rare even in countries where echinococcosis disease is highly endemic. The objective of this case report is to highlight this unusual and rare hydatid cyst presentation to avoid incorrect diagnosis and management. In our case, preoperative evaluation guided the diagnosis toward cystic pancreatic neoplasms, leading us to contemplate a radical surgical approach (Pancreaticoduodenectomy). Pancreatic hydatid cysts can be confused with cystic pancreatic neoplasms, it should always be considered as a differential diagnosis in endemic areas, to prevent misdiagnosis and inappropriate management.
