Item Caso Clínico: Agenesia pericárdica, diagnóstico imagenológico de una patología infrecuente(2020) Aguilera, Guillermo; Skoknic, Velimir; Aguirre, Javiera; Alegría, JuliaLa agenesia pericárdica congénita es una condición infrecuente, que generalmente cursa de forma asintomática y es diagnosticada como hallazgo radiológico. Sin embargo, se describe la asociación con malformaciones cardiacas y herniaciones del miocardio con el subsiguiente riesgo de muerte súbita. La radiografía de tórax es un pilar fundamental para la sospecha diagnóstica. Presentamos un caso clínico de una paciente de 11 años que consulta por dolor torácico y disnea, que frente a los hallazgos típicos en radiografía de tórax se sospecha agenesia pericárdica, posteriormente confirmada con TC y RM.Publication Diaphragmatic hernias: classifications and spectrum of presentations in computed tomography, magnetic resonance and plain radiography(2025) Ríos, Patricia; Constenla, Diego; Cristi, Joaquín; Alegría, Julia; Silva, Claudio; Schiappacasse, GiancarloDiaphragmatic hernias represent a frequent pathology in radiological practice. A congenital or acquired defect in the diaphragm facilitates the passage of abdominal structures into the thoracic cavity. Their clinical relevance varies widely from benign and incidental findings (mostly), to potentially life threatening. The objective of this work is to review the range of findings in computed tomography of diaphragmatic defects in adult patients, categorized according to location and origin, as well as their possible complications. We include a brief description of the embryological development and normal anatomy of the diaphragm, to understand this entity.Item Revisiting a Forgotten Organ: Thymus Evaluation by PET-CT(2020) Hasson, Daniel; Schiappacasse, Giancarlo; Alegría, Julia; Silva, ClaudioIncidental thymic lesion findings have increased. An adequate characterization of these lesions in positron emission tomography/computed tomography (PET-CT) is essential, since it is used as part of many oncological planning procedures. Representative cases have been selected regarding the most important aspects of thymus imaging in PET-CT and how this technique can contribute to an accurate diagnosis or treatment planning. Specifically, we present a general description of common thymic lesions and and simulated thymic disease, with an emphasis on PET-CT findings, also incorporating examples of magnetic resonance imaging (MRI).
