RESUMO
Hydatid cyst is usually located in the liver and lungs, rare cases showing localization in other organs or tissues. In the unusual location, echinococcosis is an excluding diagnosis that is established only after microscopic evaluation. Our first case occurred in a 67-year-old female previously diagnosed with pulmonary tuberculosis and hospitalized with persistent pain in the hip joint. The clinical diagnosis was tuberculosis of the joint, but the presence of the specific acellular membrane indicated a hydatid cyst of the synovial membrane, without bone involvement. Fewer than 25 cases of joint hydatidosis have been reported in literature to date. In the second case, the intramural hydatid cyst was incidentally discovered at autopsy, in the left heart ventricle of a 52-year-old male hospitalized for a fatal brain hemorrhage, as a result of rupture of an anterior communicating artery aneurysm. The conclusion of our paper is that echinococcosis should be taken into account for the differential diagnosis of cystic lesions, independently from their location.

A case of acute carpal tunnel syndrome (CTS) due to filarial infection is reported in a resident of Newfoundland, Canada. The patient presented with classical symptoms and signs of acute CTS and a filarial worm was identified in synovial tissue removed during surgery that was morphologically consistent with the genus Brugia. Antifilarial antibodies were present in serum. Surgical removal of the infected tissue, without administration of antifilarial drugs, proved adequate in eradicating the infection and a subsequent serum sample was negative for antifilarial antibodies. The patient remains asymptomatic more than two years after surgery. This case is unusual in its clinical presentation and geographic location.

Most hydatid cysts are found in the liver or lungs but occurrence in other locations is possible. The purpose of this report is to describe three cases involving cysts locate in the ovary, joint, and thyroid. Clinical findings associated with these uncommon locations were poorly specific and diagnosis required histological examination after surgical exploration. Imaging and serology were useful to differentiate hydatid cyst from benign or malignant tumor disease but often failed to achieve definitive differential diagnosis. Thorough investigation is necessary to rule out more common locations in the liver or lung. Continued surveillance is needed for early detection of recurrence. Preventive campaigns are necessary in endemic areas, such as Morocco.

Schistosomiasis is a common parasitic infestation in Egypt. We describe the case of a 24-year-old Egyptian man who presented with the signs of acute septic arthritis of the hip and in whom biopsy subsequently revealed schistosome ova in the synovium.

The authors describe a case of echinococcosis of the tibia which occurred twice in seven years, the first time with signs of active involvement of the knee joint. Certain special aspects of articular echinococcosis, not up to now reported in the literature, are dealt with. The conclusion reached is that in an articular site the parasite can give rise either to a veritable "echinococcal" arthritis or, as in the case presented, to a the synovial affection which cannot be defined as "echinococcal" because the synovium did not contain living larval forms of the parasite, but only microscopic chitinous inclusions, arising from the disintegration of sterile hydatids, which had escaped from the adjacent bony focus into the joint. The synovium reached to their presence with an intense inflammatory response of a predominantly histiocytic nature. The term "meta-echinococcal arthrosynovitis" is suggested as a more accurate designation of this syndrome.
