Intramural hydatid cyst of descending aorta complicated by false aneurysm

Hydatid cyst of the middle mediastinum complicated by fistulated ascending aorta: A case report and review of the literature

Clinicians must pay attention to the clinical presentation and consequences of hydatid cysts in rare sites. Cysts close to the aorta require planning and assistance of a cardiac or vascular surgeon before surgical intervention can be considered.

Saccular mycotic aneurysm of descending thoracic aorta secondary to vertebral hydatid disease: A rare case

BACKGROUND/OBJECTIVE

Hydatid disease of the aorta is very rare. Hydatid disease can result in saccular aneurysm of the thoracic and abdominal aorta.

CASE REPORT

We report a rare case of saccular aneurysm of the distal descending thoracic aorta. The diameter of the aneurysm was 60 mm. It was managed by Thoracic Endovascular Aneurysm Repair. After 41 months, computed tomography angiography revealed a multi-loculated cystic lesion with 86 × 83×80 mm dimensions in the prevertebral area at the T10-T11 level with bony destruction and erosion of the anterior margin of the vertebral bodies. A computed tomography-guided fine-needle aspiration of the paravertebral cystic lesion was performed. Microscopic study of the fine-needle aspiration specimen demonstrated Echinococcosis granulosus diagnostic of hydatid disease.

CONCLUSION

It is concluded that the case was a mycotic aneurysm of the thoracic aorta secondary to vertebral hydatid disease.

Abdominal Aortic Occlusion by Hydatid Cysts

Hydatid disease is a parasitic infestation caused by the larval stage of Echinococcus . It can infest any part of the body; however, aortic hydatid disease is rare. Involvement of the abdominal aorta is usually due to embolization from cardiac hydatid cysts or direct invasion and can be present at intravascular or intramural locations. Aortic hydatid disease may present with fatal complications, such as anaphylaxis, pseudoaneurysm formation, systemic embolism, and arterial occlusion.

Endovascular treatment of the descending thoracic aorta in a patient with a hydatid pseudoaneurysm

We present a patient affected by systemic hydatidosis with an unusual localization in the thoracic aorta. The pseudoaneurysm, which was treated 8 years ago with conventional surgery, was retreated with an endovascular procedure. The particular evolution of the pathology needed further endovascular intervention. Endovascular exclusion is not the final solution of the disease but protects against rupture of the vessel and systemic dissemination of the disease.

Hydatid cyst of the abdominal aorta and common iliac arteries complicated by a false aneurysm: a case report

The rupture of hydatid cysts into the abdominal aorta is an unusual and serious complication of the hydatid disease. The authors describe a case of a 12-year-old girl with hydatid disease presenting as a retroperitoneal mass invading the wall of the abdominal aortic bifurcation and complicated by a false aneurysm. Difficulties of preoperative diagnosis and operative management were discussed, and the literature was reviewed.

Pictorial essay. Various locations of cystic and alveolar hydatid disease: CT appearances

Hydatid disease (echinococcosis) is a parasitic infection caused by the larval stage of the tapeworm Echinococcus. In humans, the two main forms are cystic hydatid disease, caused by E. granulosus, and less frequently alveolar hydatid disease, caused by E. multilocularis. They can be found in various sites in the body. The purpose of this essay is to illustrate the CT appearances of cystic and alveolar hydatid disease in various locations.
