Traumatic pneumatocele: an unusual presentation of blunt chest trauma in a 21-year-old patientTraumatic pneumatocele, or traumatic pulmonary pseudocyst, is a rare complication of blunt chest trauma, characterized by multiple or unique cavitary lesions, with well-defined fibrous walls without epithelial lining. It represents a diagnostic challenge due to the higher prevalence of other etiologies of lung cavities, nonspecific clinical features and the under-reported nature of this pathology. We present the case of a 21-year-old male with fever and chest pain after a blunt chest trauma in a motorcycle accident, with identification of a cavity in the right upper lobe, surrounded by ground glass opacities. Antibiotic therapy was administered after clinical suspicion of superinfection, however, the cavitary lesion was attributed to the trauma. Occasionally, traumatic pulmonary pseudocysts are not identified during initial assessment, therefore, clinical and imagenologic follow-up is essential.
