Case Presentation:
A 10-year-old male patient was evaluated in another center with a complaint of headache that started nine months ago. The cranial magnetic resonance imaging (MRI) examination showed multiple cystic lesions. The results of the serological tests were negative. Surgical treatment was performed, and intraoperative evaluation was compatible with HCD. The patient was referred to our clinic for treatment planning upon detecting transthoracic echocardiography (TTE) findings consistent with a CHC lesion in the left ventricular apex.
In the first evaluation, there were no pathological signs in the patient’s neurological, abdominal, pulmonary, and cardiac physical examinations. Since bilateral lower extremity pulses could not be palpated, aorta-lower extremity computed tomographic angiography imaging (CTA) was performed in addition to cranial, abdominal, and cardiac(MRI). In the cranial MRI, a contrasting multiple hydatid cyst lesion was observed in the bilateral cerebral hemispheres, which was smaller than in the previous MRI. CTA of the aorta and lower extremities showed occluded abdominal aorta and iliac arteries in a 5 cm segment. Femoral arteries were filling with collaterals. On cardiac MRI, the hydatid cyst lesion at the apex of the left ventricle (LV) was seen as opening into the ventricle and causing aneurysmatic dilatation in the myocardium.[Figure 1]
The patient’s occlusion of the abdominal aorta was compatible with systemic embolism due to a ruptured CHC. No other organ involvement was observed in the radiological evaluation. The only data we have regarding the etiology is that the patient had a brief history of feeding a stray cat at home two years ago. The patient was surgically repaired with the Dor procedure (aneurysmectomy and circular endoventricular patch plasty). [Figure 2]The postoperative period was uneventful. The patient was followed up regularly for five years by the local cardiovascular surgeon in coordination with our clinic.
