Bula gigante secundaria a neumonía adquirida en la comunidad en niños / Giant Bulla Secondary to Community-Acquired Pneumonia in Children

Introducción: Los neumatoceles y las bulas pulmonares son lesiones que se observan en los niños casi siempre asociadas a neumonías infecciosas, aunque sus causas pueden ser diversas. La importancia clínica de estos procesos radica en el peligro de crecimiento progresivo, que puede comprometer las funciones respiratoria y cardiovascular. Objetivo: Describir las experiencias derivadas del proceso de diagnóstico por imágenes y del tratamiento invasivo de casos atendidos. Presentación de los casos: Desde finales de 2021 y durante un período de un año, se atendieron, en la unidad de cuidados intensivos pediátricos del Hospital Pediátrico Universitario de Cienfuegos, cinco niños con neumonías extensas, que desarrollaron bulas de gran tamaño varios días después del tratamiento antimicrobiano adecuado. Estas necesitaron drenaje y aspiración percutáneos debido a su magnitud y a la presencia de síntomas cardiovasculares. Conclusiones: Las bulas que aparecieron como complicación de la neumonía en el niño pueden presentarse con una frecuencia no despreciable, y hay que mantenerse atentos a su evolución, porque, a diferencia de los neumatoceles, pueden crecer progresivamente y comprometer las funciones respiratoria y cardiovascular. El drenaje percutáneo y aspiración continua por cinco días resultó un método seguro y eficaz para tratar estos procesos(AU)

Introduction: Pneumoatoceles and pulmonary bullae are lesions that are observed in children almost always associated with infectious pneumonia, although their causes may be diverse. The clinical importance of these processes lies in the danger of progressive growth, which can compromise respiratory and cardiovascular functions. Objective: To describe the experiences derived from the imaging process and the invasive treatment of treated cases. Presentation of the cases: Since the end of 2021 and for a period of one year, five children with extensive pneumonia were treated in the pediatric intensive care unit of the University Pediatric Hospital of Cienfuegos, who developed large bullae several days after appropriate antimicrobial treatment. The bullae required percutaneous drainage and aspiration due to their magnitude and the presence of cardiovascular symptoms. Conclusions: The bulla that appeared as a complication of pneumonia in the child can occur with a not negligible frequency, and it is necessary to be attentive to their evolution, because, unlike pneumoatoceles, can grow progressively and compromise respiratory and cardiovascular functions. Percutaneous drainage and continuous aspiration for five days was a safe and effective method to treat these processes(AU)

Frontal sinus pneumocele: case report and literature review / Pneumocele do seio frontal: relato de caso e revisão da literatura

The authors report a rare case of frontal sinus pneumocele in a 26-year-old female patient assessed by computed tomography.

Two Cases of Pneumocele of Maxillary Sinus / 대한이비인후과학회지

Pneumocele is a rare disease involving one or more paranasal sinuses. It is defined as abnormal dilatation of paranasal sinus, which is air-filled with either focal or generalized thinning of bony sinus walls. The aim of pneumocele treatment is two-fold: to re-establish permanent pressure equilibrium in the involved sinus and to correct the possible facial deformities. The first goal can be achieved by middle meatal antrostomy. When alterations of the maxillary or orbital contour are present, corrections can be obtained by osteotomies through Caldwell-Luc or an infraorbital approach. We report two cases of pneumocele of maxillary sinus. The first case was treated with osteotomy via Caldwell-Luc approach and the second case was treated simultaneously with osteotomy and rhinoplasty. No recurrence was observed after surgical treatment in both cases.

Post-Traumatic Pneumocele of the Frontal Sinus

A pneumocele is an abnormal dilatation of a paranasal sinus, most commonly affecting the frontal sinus. Although the etiology of pneumocele is not entirely known, several causative factors have been suggested including trauma, surgery, tumor and infection. We report here a case of post-traumatic pneumocele of the frontal sinus following a head trauma.

A Case of Pneumocele in the Ethmoid Sinus / 대한이비인후과학회지

Pneumocele is the pathologic expansion of an air-containing paranasal sinus that causes thinning of the bony sinus walls and displacement of nearby structures. This abnormality probably results from a physiological block in the rapid equilibration of intrasinus air pressure through the major sinus ostium and as a result of some abnormality producing a one-way valvular mechanism. A 41-year-old man had complained of headache, diplopia and periorbital pain on left side which aggravated after nose blowing. A computed tomographic scan showed a hyperlucent, expanded left ethmoid sinus. We treated the condition by endoscopic marsupialization of the anterior ethmoid sinus. Six months later, headache and periorbital pain have subsided, but diplopia has remained.
