Chylopericardium is a rare complication after cardiac transplantation. We report a case of a 69-year-old woman with persistent chylopericardium after a heart transplantation due to Chagas disease. Failure of conservative treatment led to dynamic contrast-enhanced magnetic resonance lymphangiography and percutaneous radiologic intervention of the lymphatic leakage and symptoms resolution.

ABSTRACT: Background: To investigate the ability of a delayed respiratory-navigated, electrocardiographically-gated three-dimensional inversion recovery-prepared fast low-angle shot (3D IR FLASH) sequence to evaluate the lower airways in children undergoing routine cardiovascular magnetic resonance (CMR). Methods: This retrospective study included pediatric patients (0–18 years) who underwent clinical CMR where a delayed 3D IR FLASH sequence was performed between July 2020 and April 2021. The airway image quality and extent of lower airway visibility were graded by two blinded readers using a four-point ordinal scale (0–3). Lower airway anatomical variants and abnormalities were recorded. Results: One hundred and eighty patients were included with a median age of 11.7 (4.6–15.3) years. Fifty-one of 180 (28%) were under general anesthesia. Overall, the median grading of airway image quality was 3 (2–3) and the extent of lower airway visibility was 3 (3–3). Interrater agreement was almost perfect (κ = 0.867 and κ = 0.956, respectively). Image quality correlated with extent of lower airway visibility (r = 0.62, p

Las malformaciones de la vena cava inferior son raras y la ausencia de la vena cava inferior intrahepática corresponde a un pequeño porcentaje de estas. En algunos casos, se puede asociar con otras anomalías, pero su mayor importancia es la asociación con malformaciones cardiacas. Generalmente es asintomática y su diagnóstico se hace usualmente de manera incidental. El diagnóstico por imágenes se realiza con escanografía, angiografía o por resonancia magnética. El caso que reportamos es una ausencia de la vena cava inferior en el segmento hepático con continuación de la ácigos.

Resumen. El síndrome linfoproliferativo postrasplante es una complicación que se presenta con una baja incidencia en los pacientes que han sido trasplantados. Sin embargo, si el diagnóstico y manejo no son oportunos su mortalidad es alta. Por esta razón el radiólogo debe estar atento al diagnóstico al interpretar estudios de este tipo de pacientes, especialmente en el año siguiente al trasplante. Presentamos el caso de una paciente con antecedente de trasplante renal y síndrome linfoproliferativo postrasplante con afección del sistema nervioso central.
