CT findings of an intracardiac bronchogenic cyst

Abstract

Bronchogenic cysts are classified as congenital bronchopulmonary foregut malformations. It is very rare for bronchogenic cysts to occur within the heart. A 59-year-old woman had a cardiac mass which was detected incidentally during a CT examination. The lesion was a hypoechoic mass with internal echoes on transthoracic echocardiography, and a well-defined hyperdense mass within an interatrial septum with poor enhancement on electrocardiography (ECG)-gated cardiac CT. The lesion was diagnosed as a bronchogenic cyst in the interatrial septum after surgical excision.

First Case of Intracardiac Foregut Cyst Occurring in the Left-Ventricular Outflow Tract

“…This patient did have a single gain mutation on microarray, however no patients with comparable duplications are identified in the literature. Although this is the first case obstructing the LVOT, 7 previous cases of intracardiac foregut cysts described in the literature have typically involved the atrial wall (1, 3–7) with one case occurring in the ventricular membranous septum (9). It is not known what the incidence of recurrence is for these cysts, though one case in the literature identified a one month recurrence (3).…”

Symptomatic Bronchogenic Cyst in a Lipomatous Interatrial Septum

“…Bronchogenic cysts are benign tumors that rarely cause symptoms [ 9 ]. Bronchogenic cysts of intracardiac origin are rare and thought to arise when a segment of the tracheobronchial tree incorrectly buds into the cardiac primordia during pulmonary branching during the third week of embryogenesis, laying rest in cardiac tissue [ 2 , 5 , 9 ]. Most cardiac bronchogenic cysts present in the pericardium, with rare occurrence in the interatrial and interventricular septa [ 4 , 6 , 12 ].…”

Quiste broncogénico. Reporte de un caso y revisión de la literatura

“…21 El ecocardiograma ha descubierto incidentalmente QB en el corazón. 22,23 Levine et al 24 publicaron un caso muy interesante de un incidentaloma descubierto por US en un feto de 15 semanas. La RM mostró una masa RM T2 de alta intensidad relacionada con la carina.…”

“…Se anota la importancia del ecocardiograma transesofágico en estos casos. De Catte www.medigraphic.org.mx et al 22 trataron quirúrgicamente un QB localizado en el tabique interauricular del corazón; y Seo et al 23 describieron otro caso en la misma localización descubierto incidentalmente por imagenología. El QB es capaz de originar arritmias cardiacas aun en ausencia de cardiopatía.…”

“…El QB es capaz de originar arritmias cardiacas aun en ausencia de cardiopatía. Seo et al 66 describieron un caso de fibrilación auricular paroxística causada por un QB subcarinal que comprimía aurícula izquierda y venas pulmonares. La arritmia en estos casos se ha relacionado con las venas pulmonares.…”
