Interventricular septum hydatid cyst presenting with acute lower limb ischemia: a case report

Abstract

Cardiac hydatid cysts are rarely seen. The presentation of an acute lower limb ischemia secondary to embolization from an interventricular hydatic cyst is also rare. We describe a case of a 30-year-old-man who presented with acute lower limb ischemia revealing hydatid cyst of the interventricular septum and septal defect, and who was operated on successfully.

Acute limb ischemia caused by ruptured cardiac hydatid cyst – A case report

“…CHC rupture has been presented with ischemia of femoral and popliteal. [17,18] To the best of our knowledge, this is the first reported case of right external iliac artery embolism in an adolescent patient due to ruptured CHC.…”

Unusual Location of Hydatid Cysts: Report of Two Cases in the Heart and Hip Joint of Romanian Patients

“…The heart can be involved in about 0.5–2.5% of all hydatid infections [ 1 , 9 ]. Localization in the left ventricle is the commonest one [ 5 ], similar to our case.…”

“…Localization in the left ventricle is the commonest one [ 5 ], similar to our case. From all of the heart echinococcosis, 4–9% of the cysts are positioned in the interventricular septum [ 5 , 9 ]. The infection occurs mostly via coronary arteries but pulmonary infection or direct invasion from the surrounding tissues is also possible [ 5 ].…”

“…However, in other patients, it can produce chest pain, palpitations, cough, dyspnea, valvular dysfunctions, pulmonary hypertension, or atrioventricular blocks [ 5 ]. The rare complications include generalized allergic-anaphylactic phenomena, ventricular tachycardia, cardiac tamponade, and pulmonary or systemic embolism with further lower limbs ischemia or brain infarction [ 3 , 5 , 9 ].…”

“…Being about an oral infection with hematogenous spread, hydatid cysts are mostly formed in the liver parenchyma (50–77% of the cases) [ 2 – 5 ]. They can also involve the lungs (15–47%) and rarely the spleen (0.5–8%) [ 1 – 5 , 9 ]. In this paper, we present 2 unusual locations of the cysts and a pertinent review of the recent literature regarding these locations.…”
