Introduction
Hydatid cyst is caused by infection with a parasite belonging to theEchinococcus family. Humans are the intermediate host of this
disease and get infected directly or indirectly after the parasite eggs
enter the digestive system. According to the WHO, it is considered a
neglected disease world-wide, as it still remains highly prevalent
despite the improvement of public health and following sanitary
protocols by humans (1,2). This disease is mostly asymptomatic and is
incidentally detected (3). Usually, only one cyst is formed during
infection, and the formation of several cysts and the involvement of
several organs is not common. The most commonly involved organ is the
liver, followed by the lung. The involvement of other organs is much
less common, and the involvement of the peritoneum and omentum is very
rare, and is usually caused by abdominal trauma, the rupture of a cyst
in the liver or other organs, and the release of parasites leading to
the contamination of the abdominal space (4). In this study, we
introduce a case of hydatid cysts in liver, spleen and peritoneum, in
which the radiological appearance and clinical symptoms had raised high
suspicion of abdominal malignancy and peritoneal seeding.
