Echocardiographic appearance of a hydatid cyst of the papillary muscle and chordae tendineae

Abstract

A 24-year-old woman with a history of hydatid disease of the lung and brain, which was treated surgically and medically with albendazole, was admitted because of syncope. Echocardiography demonstrated a mass in the anterolateral papillary muscle and chordae tendineae. Despite negative serologic tests for Echinococcus granulosus, cytology and histology of the surgically removed mass confirmed hydatid disease. The patient was discharged and treated further with albendazole and praziquantel.

Hydatid cyst of papillary muscle concomitant with brain involvement

“…However, these cysts are rarely located in the subendocardial region with intracavitary expansion. 7 Attachment of the HC at papillary muscle, as in the present case, is extremely rare [4][5][6] and concomitant brain involvement has not been previously reported.…”

“…The left ventricular (LV) is the most frequent area affected followed by right ventricular, pericardium 1–3 . However, attachment of the hydatid cyst (HC) at the papillary muscle is extremely rare 4–6 and concomitant involvement of brain has not been previously reported. Herein, we present a unique case of cerebral HC associated with papillary muscle involvement.…”
