“…Spleen, pancreas, kidney, adrenal gland, bone, gonads, muscles, brain, heart, vessels, and subcutaneous tissues may be involved by this parasitic disease (2). The aortic wall may be involved primarily and the disease may progress in its layers (3–6). The aortic wall may also be involved secondary to invasion of the cyst from adjacent tissues (7, 8) similar to that which we had encountered.…”

“…The aortic wall may also be involved secondary to invasion of the cyst from adjacent tissues (7, 8) similar to that which we had encountered. Aortic involvement may display as pseudoaneurysm (7–9), organ ischemia due to aortic occlusion (5, 6), remote ischemia due to daughter cysts embolization (10, 11, 12), simple cystic mass (3), or even aortobronchial fistula (12). Treatment in all patients with aortic involvement consists of surgical resection of the cyst and its content, and long-term medical therapy.…”

Cystic echinococcosis is a common parasitic disease in some areas and involves different organs with different presentations. Rural areas in our country are endemic with this disease. We present a case of echinococcal aortic involvement that was diagnosed incidentally by a routine chest radiogram as a mediastinal mass. Cystic echinococcosis was established as final diagnosis after magnetic resonance imaging (MRI) and ELISA studies. The patient was treated surgically through a thoracotomy and her aortic defect was repaired during the operation. She has been asymptomatic and complication free in physical examination and imaging study in follow up periods after two years. Awareness of various presentations of the disease is necessary for physicians who are occupied in endemic areas. It is rational to treat echinococcal cysts adjacent to the great vessels with the cooperation of a vascular surgeon.

“…7,8 The second possible mechanism is that the scolices erode the arterial wall of the aorta from an adjacent organ and pass into the vasa vasorum through an intimal defect. 9 Aortic pseudoaneurysm can also form by direct invasion of a hydatid cyst on the aortic wall. Intravascular growth of a hydatid cyst 10 is a rare manifestation of the disease and usually causes chronic arterial occlusion.…”

Cystic echinococcosis (hydatid cyst), caused by Echinococcus granulosus, has worldwide distribution and poses a health problem in endemic areas. Embolization of hydatid cysts into the vascular tree is an unusual manifestation of the disease. The hydatid embolism results from spontaneous or traumatic rupture of the cyst, and rare case reports of this kind are not well documented in the literature. We report a case of a hydatid embolism from a ruptured hydatid in a pseudoaneurysm of the thoracic aorta. A 45-year-old woman presented with gangrenous changes of the toes of her right foot. After embolectomy, the histopathology of the embolus was doubtful about its being blood clots around hydatid membranes. Postoperatively, computed tomography (CT) of the chest revealed a pseudoaneurysm of the descending thoracic aorta. Definitive surgery for the pseudoaneurysm was done during a second operation. Numerous hydatid cysts were evacuated from the pseudoaneurysm. This report emphasizes the need for an early diagnosis and treatment of echinococcosis before disabling and life-threatening complications occur.

“…Aortic wall hydatidosis can be diagnosed by digital subtraction angiography, computed tomography, and especially magnetic resonance imaging, which can detect the exact relationship of the cyst with the aorta. 3,4 The disease may be associated with life-threatening complications such as anaphylactic or hemorrhagic shock, systemic emboli, arterial insufficiency, and dissemination of the infection. 4 Several hypotheses have been proposed to describe how the parasite reaches the arterial wall.…”

“…Developed hydatid cysts are rarely found in the aortic wall, with only slightly over 10 cases having been reported, all involving the thoracic or abdominal aorta. 1 –6 We report a case of hydatidosis involving the ascending aorta and the left atrium.…”
