“…8 En este caso, el diagnóstico fue inicialmente asociado a otras patologías con una prevalencia más alta, como sucede con frecuencia. 7 Sin embargo, el diagnóstico final de la paciente se realizó por los hallazgos imagenológicos en la TACAR, que fueron compatibles con los resultados encontrados en el estudio de los gases arteriales y los hallazgos radiológicos. Adicionalmente, que la malformación fuese de tipo complejo pudo estar asociado con la sintomatología de presentación temprana y grave en la paciente, en concordancia con lo publicado en los estudios de Mowers et al y de C. Yu et al, que reportaron a niños con FAVP de tipo complejo, que presentaban manifestaciones secundarias a sus lesiones, tales como intolerancia al ejercicio, cianosis, hemoptisis, dolor torácico, dificultad para respirar e isquemia cardíaca.…”

Presentación de casos clínicos RESUMEN Las fístulas arteriovenosas pulmonares son malformaciones congénitas dadas por la comunicación directa anómala entre arterias y venas, con una incidencia mundial de 2-3 : 100 000 habitantes. La presentación es, en general, única, asintomática, y aparecen en forma incidental como hallazgo imagenológico en la adultez, y su tratamiento de elección es la embolización endovascular. Se describe la inusual presentación clínica en una paciente de 10 años, que ingresó por disnea, tos, cianosis central y cefalea. Se encontró hipoxemia persistente, hipocratismo digital, nódulos parahiliares pulmonares, gases arteriales con gradiente alvéolo-arterial aumentado. La tomografía axial computarizada de tórax de alta resolución confirmó la presencia de una malformación arteriovenosa pulmonar en la región parahiliar derecha, la cual no se asociaba con la enfermedad de Rendu-Osler-Weber. La paciente fue tratada con embolización endovascular transcutánea. Tras 1,5 años de seguimiento, no hubo recaídas. Son pocos los casos reportados de estas fístulas en la edad pediátrica. Palabras clave: fístula arteriovenosa pulmonar, embolización endovascular transcutánea, pediatría.

“…A PAVM is a rare vascular anomaly of the lung, in which abnormally dilated vessels provide a right-to-left shunt between the pulmonary artery and vein that may appear as a SRPL (Fig. 13a) (18,19). Despite most patients being asymptomatic, affected children may present with cyanosis, dyspnea, hemoptysis, clubbing as well as polycythemia (14,19).…”

The purpose of this current pictorial review is to define the solitary round pulmonary lesion (SRPL), to familiarize with its prevalence in the pediatric population, and, moreover, to educate radiologists on its vast differential diagnosis and imaging manifestations. Furthermore, by highlighting valuable clues, it intends to assist radiologists efficiently partake in its diagnosis, work-up, and follow-up in order to narrow down the differential diagnosis by working alongside the clinician and combining clinical information, lab results, and radiological findings.

“…Recently, it is considered that a poor ventilation, hypoxia and an increased blood perfusion could accelerate the process of vascular anomaly where a respiratory infection could act as an important factor [10][11] . Previous studies have stated rare proofs about pathogens in hemoptysis, especially associated with pulmonary vascular malformations.…”

Background: To summarize characteristics of hemoptysis in children associated with pulmonary vascular malformations, and to identify the pathological mechanism, potentially. Methods: Children were recruited who were diagnosed with hemoptysis for pulmonary vascular malformations without congenital heart disease (CHD). The demographics, history, clinical characteristics, laboratory findings, pathogens testing, imaging outcomes and prognosis were systemically reported. The nonparametric Mann-Whitney U test using SPSS 24.0 was employed to compare the continuous laboratory variables, and Fisher’s exact test was applied for data enumeration. A P-value of <0.05 was considered statistically significant. Results: In sum, 27 children were enrolled in this retrospective study with a medium age of 9.1 years old, among whom 9.1% were in preschool-group, 72.7% in school-group, and 18.2% in adolescent-group. Different hemoptysis degrees were observed from individuals, and the moderate and severe conditions were commonly in elder children. Meanwhile some antecedent symptoms were recorded, mainly cough and fever before hemoptysis occurrence. Pathogens testing indicated proofs for infection of MP in 68.2% patients, and 37.5% were further identified with MP-DNA-PCR. Images revealed interstitial changes in most hemoptysis cases, especially in the inferior lobe of right lung for cases with MP infection, and endovascular contrast detected 24 patients with abnormal bronchial arteries (BAs) causing bronchial artery-pulmonary artery fistula and 3 patients suffered from pulmonary arteriovenous fistula (PAVF). After the transcatheter plug closure, a recurrent hemoptysis occurred in 8 patients suffered from an infection of MP initially, and the OR of clinical worsening in Group 1 where cases were considered with an infection of MP, was 2:1. Conclusions: Pulmonary vascular malformations can be commonly detected in elder children. An infection of MP possibly acts as a potential trigger inducing the rupture of affected vessels, which could take a higher risk of clinical worsening.
