Left ventricular myocardial hydatid cyst: a case report
The present case appears in the journal Applied Radiology.

A 25-year-old woman presented to the cardiology department with a history of shortness of breath and palpitations. A general cardiac examination showed regular pulse with a heart rate of 74 bpm and normal blood pressure of 120/80 mm/Hg. Heart sounds were normal. Blood work showed a raised eosinophil count. Chest X-ray showed mild cardiomegaly. The ECG was normal.

Transthoracic echocardiography revealed a cystic mass within the heart. Cardiac MR imaging (MRI) was performed with ECG gating to further characterize this mass. Bright blood cine SSFP gradient 4 chamber and short axis views revealed a large, well-marginated, round mass in the lateral wall myocardium of the left ventricle (Figure 1A) which demonstrated markedly hyperintense signal brighter than blood (Figure 1B).

The mass had thin regular walls and was seen bulging into the LV cavity in the vicinity of the mitral valve. On double inversion recovery black blood T2-weighted MRI, homogeneous hyperintense fluid signal intensity in the mass indicated it to be a cyst and a surrounding thin hypointense rim was appreciated. There was no enhancement of the mass while the normal myocardium was seen enhancing on dynamic post-gadolinium inversion recovery MRI.

Final Diagnosis: Intramyocardial hydatid cyst involving the left ventricle
