    <jats:p>Objetivo: Describir un caso extremadamente raro de torsión pulmonar espontánea en una paciente sin antecedentes de trauma o cirugía torácica, y discutir su importancia clínica.Materiales y Métodos: Se analizó el caso de una paciente femenina de 56 años que presentó dolor torácico súbito. Para el diagnóstico, se emplearon métodos como el examen físico, la tomografía computarizada y la videotoracoscopia (VTC).Resultados: La VTC reveló un infarto del segmento lingular inferior por torsión pulmonar, llevando a la realización de una resección segmentaria de la língula sin complicaciones.Discusión: La torsión pulmonar espontánea es rara y generalmente se asocia con condiciones subyacentes como neumotórax, atelectasias, infecciones, derrame pleural, defectos congénitos o tumores. Este caso es inusual al carecer de dichos antecedentes, aunque se detectó una infección viral concomitante. Dada la gravedad de las potenciales complicaciones mortales, resulta crucial un diagnóstico y tratamiento oportunos.Conclusión: Se presenta un caso inusual de torsión pulmonar espontánea. A pesar de su rareza, es vital considerarlo en el diagnóstico diferencial de dolor torácico agudo.</jats:p>

    <jats:title>Abstract</jats:title><jats:sec> <jats:title>Background</jats:title> <jats:p>An intraluminal duodenal diverticulum (IDD) is an infrequent abnormality consisting of a sac-like projection within the duodenum secondary to a congenital web of the membrane in the second portion of the duodenum near the papilla of Vater, due to incomplete lumen recanalization of the embryological foregut, with a typical imaging appearance of a “windsock.”</jats:p> <jats:p>The purpose is to present the radiological and tomographic findings characteristics of “IDD.”</jats:p> </jats:sec><jats:sec> <jats:title>Results</jats:title> <jats:p>The IDD in barium upper gastrointestinal imaging and computed tomography (CT) was presented. On upper barium gastrointestinal examination, it is possible to detect an intraluminal duodenal image, that can be distended with gas or barium contrast and delimited by a thin wall (halo sign), mimicking a windsock or a double lumen. On CT, it is possible to identify a windsock sign on the duodenum, most often on the second part, distended by gas and contrast agent.</jats:p> </jats:sec><jats:sec> <jats:title>Conclusion</jats:title> <jats:p>IDD imaging in barium upper gastrointestinal imaging and CT is pathognomonic of this infrequent entity in adults that needs to be recognized by the radiologist. In our small series, IDD images of the windsock sign on barium studies and the characteristic presentation on CT can help to exclude another duodenal conditions, guiding appropriate management.</jats:p> </jats:sec>

    <jats:sec><jats:title>Background:</jats:title><jats:p> Ankle arthritis that develops after fracture accounts for a significant portion of ankle arthritis necessitating total ankle arthroplasty (TAA). It remains unknown whether TAA in postfracture patients produces equivalent outcomes to those without fracture history. The purpose of this study was to evaluate the medium-term outcomes of TAA in postfracture ankle arthritis compared to those without fracture history. </jats:p></jats:sec><jats:sec><jats:title>Methods:</jats:title><jats:p> This study reviewed 178 ankles from 171 consecutive patients who underwent TAA in our institution between 2007 and 2017 and completed a minimum 5-year follow-up. Four different TAA systems were utilized by 6 surgeons. Based on fracture history, patients were divided into 2 groups: the postfracture group (n = 63; median age 65.7 years; median follow-up 5.9 years) and the nonfracture group (n = 115; median age 64.4 years; median follow-up 6.2 years). Types and rates of complications including revision and reoperation were compared. Minimum 5-year Foot and Ankle Outcome Score (FAOS) and postoperative improvement were investigated. A subgroup analysis was performed to determine whether outcomes differ between intraarticular fracture patients (n = 43) and extraarticular fracture patients (n = 20). </jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p> Both groups exhibited comparable postoperative improvement and final FAOS scores. The postfracture group had a significantly higher reoperation rate than the nonfracture group (20 of 63, 31.7%, vs 17 of 115, 14.8%; P = .011), with gutter impingement being the most common cause. There were 3 revisions in each group. In the subgroup analysis, we found no evidence of statistical difference between the intraarticular fracture group and the extraarticular fracture group in terms of FAOS scores, revision, and reoperation rates. </jats:p></jats:sec><jats:sec><jats:title>Conclusion:</jats:title><jats:p> In this single-center, retrospective comparative study, we found total ankle arthroplasty in patients with a history of fractures around the ankle joint had no evidence of statistical difference in patient-reported outcomes and implant survivorship but led to a higher rate of nonrevision reoperation following surgery. In the much smaller subset of patients with previous fracture, we did not find that those with a history of intraarticular fracture had inferior outcomes after TAA when compared to those with a history of extraarticular fracture. </jats:p></jats:sec><jats:sec><jats:title>Level of Evidence:</jats:title><jats:p> Level III, case-control study. </jats:p></jats:sec>
