International Conference on

Hydatid disease of bone: a case report and literature review

Ayman Ismail

Mohammed VI University Hospital, Morocco

ydatid disease is a parasitic infestation caused by

larvae of the tapeworm Echinococcus. It is endemic in

Morocco and Mediterranean countries. It may develop in

almost any part of the body. The liver is the most frequently

involved organ (75%) followed by the lung (15%) and the

remainder of the body (10%). Hydatidosis of bone is rare,

accounting for only 0.5% to 2.5% of human hydatidosis. It

represents one of the most severe forms of this infection.

Case presentation:

We report the observation of a female

patient with no previous history, aged 66 years. The clinical

examination finds a swelling of the right knee evolving

for 2 years. Radiological investigations showed a poorly

limited osteolytic tumor taking the knee and the anterior

compartment of the thigh. Surgical treatment consisted of

disarticulation of the right hip. The macroscopic examination

found a multilocular lesion containing clear fluid and

daughter cysts measuring 23 cm taking the patellofemoral

joint and the anterior compartment of the thigh.

Histological examination showed a pink lamellar cuticular

membrane lined by compresed germinal epithelium

and surrounded by a polymorphous granulation tissue,

fibrosis, and an inflammatory reaction rich in eosinophils.

Because of the clinical latency of hydatid disease,

hydatid disease of bone should be considered in the

differential diagnosis of any bone mass discovered in

the human body. Surgical treatment with histologic

examination can provide a definitive diagnosis.
