Relación clínico-radiológica de Neumonía por Mycoplasma Pneumoniae confirmada mediante ADN-PCR. Hospital Dr. Roberto Gilbert Elizalde. Enero 2017 – diciembre 2019.

Abstract

Background: Mycoplasma Pneumoniae is a frequent cause of pneumonia in the pediatric population, however, clinical manifestations and radiographic findings are unexpected and may be variable in each case. Materials and methods: This is an observational, cross-sectional, analytical, and retrospective investigation was in 51 children with Mycoplasma Pneumoniae pneumonia detected by PCR test. The radiographs were evaluated by a single operator who was unaware of the information of the patients, the radiographic findings were related to the symptoms of the patients. Results: Four patterns were identified: localized reticulonodular infiltration (29%), lobar or segmental consolidation (25%), patch infiltration (25%), and peribronchial parahilar infiltration (20%). The patch infiltration pattern had a higher incidence in children older than 5 years old, longer hospitalization and more admissions to a critical area. The peribronchial parahilar infiltration pattern occurs more in children under 5 years old, it is related to shorter hospitalizations and less admission to a critical area. Pleural effusion was the main complication (14%), more than half were related to the lobar consolidation pattern. Conclusions: The associated patch infiltration and lobar consolidation patterns were more severe, in contrast to that of parahilar infiltration reflected in less morbidity. Definitive diagnosis of Mycoplasma Pneumoniae pneumonia is not possible with imaging alone, but a combination of clinical and radiographic findings can improve the diagnostic accuracy and prognosis of the disease.
