Giant isolated hydatid lung cyst: two case reports 

Abstract

Background Echinococcosis is a parasitic disease caused by Echinococcus granulosus and causes cystic lesions in the liver and lungs commonly. It is endemic in many parts of the world, and though humans are incidental hosts of the parasite, the disease can have severe consequences. Case presentation We present two patients from pastoralist (Maasai) communities in rural Tanzania with long-standing chest pain accompanied by hemoptysis. Both were managed surgically after diagnosis, but one patient died of the complications following rapture of the cyst during surgery. Histopathological evaluation of the specimens confirmed the diagnosis of giant hydatid cysts. Conclusion Animal-keeping communities such as the Maasai are at risk of echinococcosis because of their close proximity to animals. The diagnosis can be made on the basis of history and radiological as well as laboratory findings. Surgery is a recommended mode of treatment, though it carries a high risk, especially when the cyst ruptures. Primary preventive measures are thus necessary in order to avoid the secondary and tertiary complications of the management of giant hydatid cysts, which is difficult in resource-limited endemic areas.

Ruptured pulmonary hydatid cyst presenting as hemoptysis in TB endemic country: A case report

“…The imaging findings were not typical of the hydatid disease. In our scenario, the diagnosis was only considered after bronchoscopy and was confirmed by histopathological evaluation similar to the study done by Lodhia et al [ 13 ]. A study shows that other modes of diagnosis like serology and blood eosinophil count are not sensitive even in cases of ruptured hydatid cyst [ 14 ].…”

Clinical presentation and diagnosis of pulmonary hydatidosis in a cow mimicking to aspiration pneumonia

“…The clinical signs and symptoms of CE arise when the cysts compress adjacent structures and the severity depends on the location of the cyst 15 . Rupture of the cyst may cause hypersensitivity, severe anaphylaxis and cardiac arrest 3 .…”

“…12 The clinical signs and symptoms of CE arise when the cysts compress adjacent structures and the severity depends on the location of the cyst. 15 Rupture of the cyst may cause hypersensitivity, severe anaphylaxis and cardiac arrest. 3 In our case, HC located at the tracheal bifurcation possibly pressed the airway, resulting in severe dyspnoea and eventually death of the animal.…”

Pulmonary hydatid cyst disease: a retrospective study

“…It is an important cause of morbidity and mortality in many parts of the world [1]. Lung involvement with hematological spread is one of the most common accompanying conditions, and it may present with extrapulmonary involvement in this region due to the close proximity of the lung [1][2][3]. The aim of the present study was to compare our results with the relevant literature.…”
