[Cardiac hydatid cyst. Which imaging modality for an accurate diagnosis?]

Area of Science:

• Cardiology
• Radiology
• Parasitology

Background:

• Cardiac echinococcosis is a rare parasitic infection with potentially severe consequences, including cyst rupture.
• Clinical presentation is often nonspecific and diagnosis can be challenging.
• Chest radiography may offer initial clues, but advanced imaging is essential.

Observation:

• This case highlights the diagnostic utility of various non-invasive imaging modalities.
• Transesophageal and transthoracic echocardiography, CT, and MRI provide detailed morphological and topographical information.
• MRI offers functional analysis of cyst movement, assessing rupture risk and impact on myocardial function.

Findings:

• Advanced imaging techniques, particularly MRI, enable accurate diagnosis of cardiac hydatid cysts.
• These methods precisely delineate cyst wall, content, and relationship with cardiac structures.
• Assessment of cyst mobility and deformability aids in predicting rupture risk.

Implications:

• Accurate diagnosis through advanced imaging is critical for managing cardiac echinococcosis.
• Understanding cyst-cardiac relationships guides surgical or therapeutic interventions.
• Improved diagnostic accuracy can lead to better patient outcomes and reduced morbidity.
