Bronchogenic cyst of the left lower lobe associated with severe hemoptysis

Severe mediastinitis caused by an infected bronchogenic cyst

Bronchogenic cysts (BCs) are congenital foregut malformations and usually asymptomatic, thin-walled, incidentally diagnosed cysts which can be easily resected by a minimal invasive approach at this time point. However, they may develop symptoms such as infection, bleeding or compression of adjacent structures. There is no consensus about the risk of developing complications during a lifetime; however, recent reports suggest a higher incidence than initially believed. Here, we report a case of severe life-threatening mediastinitis emerging from an infected BC requiring complex surgery, which could have been avoided if surgery had been performed at an early, asymptomatic stage.

Surgery in congenital lung malformations: the evolution from thoracotomy to VATS, 10-year experience in a single center

Background

Congenital lung malformation is an umbrella term and consist of various kind of parenchymal and mediastinal pathologies. Surgical resection is often required for diagnosis and curative treatment.

We aimed to review our experience in surgical treatment for congenital lung disease and present the role of minimally invasive surgery.

Methods

Surgical resections performed for benign lesions of the lung and mediastinum between January 2009 and May 2019 were retrospectively analyzed. Patients who were found to have congenital lung malformation as a result of pathological examination were included in our study. Distribution characteristics of the patients according to congenital lung malformation subtypes, differences in surgical approach and postoperative results were investigated.

Results

A total of 94 patients who underwent surgical resection and were diagnosed with the bronchogenic cyst, sequestration, bronchial atresia, congenital cystic adenomatoid malformation (CCAM), or enteric cyst as a result of pathological examination were included the study. There were no significant differences between pathological subtypes in the postoperative length of hospital stay and drainage duration however, perioperative complication rate was higher in the sequestration group. In addition, in the first three days postoperatively, the mean pain score was found to be lower in the VATS group compared to thoracotomy.

Conclusions

Congenital lung malformations consist of a heterogeneous group of diseases and the surgical treatment in these patients can range from a simple cyst excision to pneumonectomy. Video-assisted thoracoscopic surgery should be considered as the first choice in the surgical treatment of these patients in experienced centers.

A Clinical Analysis of Pharyngeal Bronchogenic Cysts in the Pharynx of Children

Objective: This study was designed to summarize the clinical characteristics, diagnosis and treatment of pharyngeal bronchogenic cysts in children to help in making the correct diagnosis and developing an appropriate treatment plan. Methods: The clinical data of 13 children with bronchogenic cysts in the pharynx, who were treated in otolaryngology head and neck surgery department between September 2013 and July 2019, were analyzed retrospectively. The clinical characteristics were evaluated, and the related factors for diagnosis and treatment were analyzed. Clinical characteristics and imaging features of three cases whose lesions located in the nasopharyngeal, oropharynx, and laryngopharyngeal were demonstrated. Results: All 13 children were male, the youngest being 4 days old, the oldest 6 years and 6 months, and the median age being 1 year and 4 months. Eight patients were diagnosed during a physical examination, and five patients visited the doctor with different degrees of upper airway obstruction. The mass was located in the nasopharynx in one patient, in the oropharynx in eight patients, and in the laryngopharynx in the other four patients. Computed tomography (CT) scanning, which is helpful for a topical diagnosis, showed a dense homogeneous mass. Electronic nasopharyngoscopy showed cystic masses of different sizes in the pharynx. All the children underwent cyst resection under general anesthesia, and the postoperative pathology result was a bronchogenic cyst. One child was lost to follow-up, but the remaining 12 children were followed up for between 6 months and 6 years, during which no recurrence of a cyst was found. Conclusion: Bronchogenic cysts are a rare cyst of the head and neck, and the most common site of the cyst is the oropharynx. The impact on airway obstruction depends on the location and size of the cyst. CT scanning is of great significance for diagnosis. Surgical treatment should be carried out as soon as possible after diagnosis, as surgery is the most effective way to treat bronchogenic cysts. Follow-ups should be carried out regularly to prevent cyst recurrence.

Clinical characteristics and management of intrathoracic bronchogenic cysts: a single center experience

Background

The aim of this study is to investigate the clinical characteristics and management of intrathoracic bronchogenic cysts.

Materials and Methods

Twenty-four (n=24) patients with intrathoracic bronchogenic cysts were treated surgically between August 1990 and December 2009 at our institution. Patients were divided into two groups by bronchogenic cyst location: mediastinal or intrapulmonary. Symptoms at diagnosis, radiologic findings, locations, surgical methods, pathological findings, and surgical outcomes were investigated retrospectively from consecutive patient medical records.

Results

There were 12 females (50.0%). The mean age was 26.8 (range, 5 to 64) years. The mean follow-up period was 27.3 (range, 1 to 121) months. There were 15 (62.5%) mediastinal and 9 (37.5%) intrapulmonary bronchogenic cysts. Symptoms occurred in 8 patients with mediastinal bronchogenic cysts (53.3%) and 5 patients with intrapulmonary bronchogenic cysts (55.6%) (p=1.000). On computed tomography (CT), 7 patients (46.7%) showed homogenous solid masses in mediastinal bronchogenic cysts and five (55.6%) patients exhibited heterogeneous cystic masses with air-fluid levels in intrapulmonary bronchogenic cystic masses. Open thoracotomy was performed in 17 (70.8%) patients, and video-assisted thoracic surgery was performed in 7 (29.2%) patients. On pathological findings, there were 16 (66.7%) complicated cysts, and in 13 symptomatic patients, 11 (84.6%) patients had complicated cysts. There was no operative death in this study. During the follow-up period, no recurrence was detected.

Conclusion

Intrathoracic bronchogenic cysts have a wide variety of clinical characteristics and radiologic findings. Even though some patients do not experience symptoms and signs caused by bronchogenic cysts, serious symptoms and complications may develop with the passage of time.

Syncope and facial blushing due to giant intrapulmonary bronchogenic cyst

A 43-year-old man presented with dizziness, head instability, and facial reddening, always in relation to body posture and without fever or systemic manifestations. Chest radiography revealed a large cavity with an air-fluid level in the right upper hemithorax. A right upper lobectomy was performed to remove a large bronchogenic cyst. The presentation with cardiac but no respiratory symptoms is uncommon but should be considered in the differential diagnosis of patients with intrathoracic cysts.

Bronchogenic cysts of the lung: report of 29 cases

BACKGROUND

Intrapulmonary bronchogenic cysts are congenital anomalies of the tracheobronchial tree and foregut. The aim of this retrospective study was to review the diagnosis, clinical and histological features, operative techniques, outcomes and follow-up of intrapulmonary bronchogenic cysts treated in a single institute.

METHODS

Twenty-nine patients with intrapulmonary bronchogenic cysts were treated surgically between 1990 and 2005. There were 17 female and 12 male patients and their ages ranged from 7 to 68 years. Patients were divided into two groups according to surgical procedure. Resection (lobectomy or wedge resection) was performed on Group I (n=18), and partial excision with de-epithelisation was performed on Group II (n=11).

RESULTS

Twenty-five patients (86.2%) were symptomatic. Cough and sputum were the most common symptoms. Twenty-four of the 29 BCs were simple cysts (82.7%) whereas 5 (17.3%) were complicated cysts. Postoperative hospital stay was 4.55+/-0.86 days in group I and 6.54+/-3.34 days in group II (P=0.172). Complications in Group I were pneumonia in one case and wound infection in two cases; prolonged air leakage were observed in two cases of Group II. No statistical difference was determined between the complication rates of the two groups (P=0.91). However a significant difference was determined between the complication rates of simple and complicated cysts (P=0.026). Two cases in Group II showed recurrence, whereas no recurrence occurred in Group I. (P=0.065) No postoperative mortality was observed in any of the groups.

CONCLUSIONS

All bronchogenic cysts should be treated surgically. We believe that partial excision with de-epithelisation may be an alternative to resection in symptomatic patients with limited respiratory capacity.

Intrapulmonary bronchogenic cysts: computed tomography, clinical and histopathologic correlations

BACKGROUND/PURPOSE

Bronchogenic cysts (BCs) are usually located in the mediastinum and they occur less commonly in the lung parenchyma. This study investigated the findings from computed tomography (CT) images, clinical presentation and histopathologic findings of intrapulmonary BCs.

METHODS

From the last 7 years, the CT images of 20 patients (12 females, 8 males; mean age, 38.8 +/- 21.7 years; median age, 34 years) with intrapulmonary BC were available. Contrast-enhanced CT findings were characterized and correlated with clinical presentation and histopathologic findings (using Fisher's exact tests).

RESULTS

The majority of intrapulmonary BCs were subpleural in location (55%), in the lower lobes (60%), symptomatic (80%), and in adults (90%). Three CT patterns were identified: cyst with content of fluid attenuation (9 patients), cyst with air and fluid content (9 patients), cyst with content of soft tissue attenuation (2 patients). Preoperative diagnosis of intrapulmonary BC was correct in only 20% using the CT criteria of cysts with fluid attenuation and without anomalous blood supply. Cysts with air component were significantly larger than those without air component (p = 0.0452), but cyst size and air component were not correlated with clinical presentation. Surrounding infiltration or thick wall on CT were significantly correlated with the presence of any clinical symptom (p = 0.014) or fever (p = 0.042). CT findings of surrounding consolidation, ground glass opacity or thick wall were significantly correlated with chronic inflammation or pneumonic change on histopathology (p = 0.0008).

CONCLUSION

There is a wide spectrum of intrapulmonary BCs that have CT findings that are correlated with clinical presentations and histopathologic findings.

Mycobacterial infection of intraparenchymal bronchogenic cysts

Bronchogenic cysts (BCs) may rarely cause some interesting and unusual complications. Although infection is a common complication of BCs, there are only two patients with BC infected with mycobacterium in English literature. Two intraparenchymal BCs infected with mycobacterium are presented here as unusual complications. Cystectomy was performed for the cysts. They were given antituberculosis treatment. No complication or recurrences were detected in follow up period.
