Pediatric spontaneous pneumomediastinum is known to have a benign course. Despite this, there is no consensus or standardization for the workup and management. There are often a variety of imaging studies performed for patients with similar presentations.This is a retrospective chart review evaluating the presentation, workup, and management of all pediatric patients with a primary diagnosis of spontaneous pneumomediastinum over a 5-year period at a children's hospital.Of the 62 patients, the initial workup consisted of either a chest x-ray (CXR) only (n = 31, 50%), a chest computed tomography scan only (n = 11, 18%) or both (n = 14, 23%); additionally, some patients came with 'other' imaging only (n = 3, 5%) or no imaging (n = 3, 5%). Twenty-seven patients (44%) underwent an additional CXR and 19 (31%) underwent an esophagram. All esophagrams were negative for an esophageal leak. A presenting symptom of pain was associated with a hospital stay of less than 24 h (p = 0.008) while shortness of breath (p = 0.0005) and emesis (p = 0.0006) were associated with a hospital stay of greater than 24 h. Associated diagnoses of respiratory infections (p = 0.02) and gastrointestinal issues (p = 0.006), such as hyperemesis, were associated with inpatient admission.Pediatric patients with spontaneous pneumomediastinum benefit from evaluation, management, and treatment based on their presenting symptoms. There is an opportunity to decrease unnecessary radiation exposure in this patient population with fewer CXRs and avoidance of esophagrams, neither of which alter management.Level III. |
