“…Evaluation of thoracic diseases through CT has been the motive for a series of recent publications in the radiology literature of Brazil ( 16 - 23 ) . Chest CT is also the method of choice for diagnosing bronchial atresia, because it is the most sensitive in showing the findings typical of the disease, such as lung hyperinflation.…”

Objective: To evaluate computed tomography (CT) findings in 23 patients with bronchial atresia. Materials and Methods: The CT images were reviewed by two radiologists who reached decisions by consensus. We included only patients who presented with abnormalities on CT and in whom the diagnosis had been confirmed by pathological examination of the surgical specimen (if the lesion was resected). The CT scans were assessed in order to identify the main findings and to map the distribution of the lesions (i.e., to determine whether the pulmonary involvement was unilateral or bilateral). Results: The main CT finding was the combination of bronchocele and hyperinflation of the distal lung. That combination was observed in all of the patients. The lesions were unilateral in all 23 cases, being seen predominantly in the left upper lobe, followed by the right lower lobe, right upper lobe, middle lobe, and left lower lobe. Conclusion: The diagnosis of bronchial atresia can be reliably made on the basis of a finding of bronchocele accompanied by hyperinflation of the adjacent lung parenchyma.

“…The most common symptoms reported by patients include dyspnea, cough, puffy face, subcutaneous emphysema, and retrosternal and back pain [ 12 ]. On physical examination, the Hamman sign can be detected [ 13 ] and is present in about half of the cases of mediastinal emphysema or left pneumothorax [ 14 ]. In the vast majority of cases, a clicking sound occurs during systole.…”

A 39-Year-Old Woman with Cervicofacial and Mediastinal Emphysema 10 Hours After an Elective Lower Molar Dental Extraction

Patient: Female, 39-year-old Final Diagnosis: Pneumodeiastinum Symptoms: Chest discomfort • dyspnea • oedema of the face Medication: — Clinical Procedure: Antibiotics • CT scan Specialty: Critical Care Medicine Objective: Rare disease Background: Mediastinal emphysema, also called pneumomediastinum, is a very infrequent condition in patients reporting to an Emergency Department. Mediastinal emphysema is the pathologic presence of free air enclosing the mediastinal structures. In the case of chest pain in a young healthy adult, pneumomediastinum as a differential diagnosis will undoubtedly be omitted. This would be especially likely if the symptoms are not preceded by an injury, intense vomiting, or an infection in this area. Case Report: We present a case in which a previously healthy 39-year-old woman experienced painless progressive face and neck swelling, dyspnea, and retrosternal pain several hours after a dental procedure. Physical examination revealed crackles on palpation of the skin on the right part of the face, neck, and chest. Neck and chest computed tomography confirmed subcutaneous neck and upper chest emphysema and pneumomediastinum. The patient was transferred to the thoracic surgery ward. After 2 days of prophylactic intravenous administration of antibiotics, she was discharged for further scheduled treatment at the Maxillofacial Surgery Clinic. Conclusions: This report presented a rare case of a woman who reported to the Emergency Department with subcutaneous and mediastinal emphysema following routine molar dental extraction. Emergency Department physicians should be aware of the possibility of delayed complications after standard dental procedures. A detailed medical history and clinical examination will enable making a correct diagnosis so as not to jeopardize the health of a patient, and in the case of the development of mediastinitis, even the patient’s life.

“…The findings are clinically significant because most previous reports involved young adults. We reviewed the relevant literature regarding cases involving children aged <15 years and retrieved 25 articles reporting 32 cases [3], [4], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29]. In total, 22 boys and 10 girls aged between 1 and 15 years (mean age: 9 years) were identified.…”

Pneumorrhachis refers to the clinical presentation of air within the spinal canal, and it is rarely associated with pneumomediastinum, particularly in young children. Pneumorrhachis associated with pneumomediastinum is generally asymptomatic. Here we report 2 unusual cases involving very young children with pneumorrhachis secondary to pneumomediastinum and present a review of the relevant literature. Case 1 involved a 4-year-old girl who presented with wheezing, violent coughing, and dyspnea associated with bronchiolitis. Case 2 involved a 3-year-old boy who presented with wheezing, violent coughing, and dyspnea associated with interstitial pneumonia possibly caused by graft-versus-host disease with human herpesvirus 6 infection after allogeneic hematopoietic stem cell transplantation. In both cases, pneumorrhachis improved with oxygen inhalation therapy and treatment of the underlying disease. Pneumorrhachis is rarely associated with neurological problems; however, decompressive laminectomy may be indicated to relieve the air block. Because pneumorrhachis is rare in children and neurological sequelae may be difficult to identify, close clinical, and radiographic observations are necessary. Plain radiography is not sufficient, and computed tomography should be performed to rule out intraspinal air.
