Pulmonary sparganosis mansoni is rare in humans and bronchial sparganosis mansoni has not been reported. We reported a patient with a soft-tissue mass in the right hilum area on a chest computed tomography (CT) scan that was suspected of being lung cancer. Bronchoscopy identified sparganum larvae. Bronchial sparganosis mansoni accompanied by abnormal hyperplasia was diagnosed by histopathology. We introduced our experience and reviewed the clinical characteristics of three pulmonary sparganosis mansoni cases and three pleural cavity sparganosis mansoni cases that have been reported.

We report a case of a 70-year-old woman who presented with mild exertional dyspnea and cough. Fiberoptic bronchoscopic findings revealed an endobronchial polypoid lesion with stenotic bronchus. The lesion was very similar to endobronchial tuberculosis. Histologic examination of the biopsy specimen demonstrated Actinomyces infection. There was a clinical response to intravenous penicillin therapy. Primary endobronchial actinomycosis must be considered in the differential diagnosis of an endobronchial lesion, especially endobronchial tuberculosis in Korea.

A 32-yr-old male patient with recurrent pneumothorax associated with bronchial atresia of the subsegmental branch of the posterior segmental bronchus of the right upper lobe was successfully treated with right upper lobectomy. Before surgery, the bronchial atresia with pneumothorax was suspected on the chest radiograph and CT scans, which showed the findings of bronchocele with localized hyperinflation of the right upper lobe. The examination of surgical specimen from the resected right upper lobe suggests that the cause of the recurrent pneumothorax was the rupture of the subpleural bullae in the hyperinflated lung segment distal to the atretic bronchus.

Extranodal marginal zone lymphoma is a low-grade B cell lymphoma that presents with an indolent clinicopathologic nature. Although this tumor can occur in various sites, including the gastrointestinal tract and lungs, it develops and spreads extremely rarely along the trachea and central airway. We report a case of extranodal lymphoma of mucosa-associated lymphoid tissue with tracheobronchial involvement. An 83-year-old woman presented with a cough and dyspnea. Bronchoscopic evaluation confirmed diffuse, multiple nodular lesions in both the trachea and large bronchi, and she was diagnosed with an extranodal marginal zone lymphoma of the tracheobronchial tree. After systemic chemotherapy, she survived for more than 18 months.

PURPOSE: Upper and lower respiratory tract pathologies are believed to be interrelated; however, the impact of upper airway inflammation on lung function in subjects without lung disease has not been evaluated. This study investigated the association of CT finding suggesting chronic sinusitis and lung function in healthy subjects without lung disease. METHODS: This was a retrospective study of prospectively collected data from 284 subjects who underwent a pulmonary function test, bronchial provocation test, rhinoscopy, and osteomeatal unit computed tomography offered as a private health check-up option. RESULTS: CT findings showed that the sinusitis group had a significantly lower FEV1/FVC ratio than subjects without sinusitis finding (78.62% vs 84.19%, P=0.019). Among the sinusitis group, subjects classified by CT findings as the extensive disease group had a slightly lower FEV1/FVC than those of the limited disease group (76.6% vs 79.5%, P=0.014) and the associations were independent of the presence of airway hyperresponsiveness. The subjects with nasal polyp had also lower FEV1 and FEV1/FVC than subjects without nasal polyp (FEV1: 100.0% vs 103.6%, P=0.045, FEV1/FVC: 77.4% vs 80.0%, P=0.005). CONCLUSIONS: CT findings suggesting chronic sinusitis and nasal polyp were associated with subclinical lower airway flow limitation even in the absence of underlying lung disease.

The bronchoarterial (BA) ratio measured with computed tomography is widely used in human medicine to diagnose bronchial dilation or collapse. Although use of the BA ratio in veterinary medicine has been recently studied, this has not been evaluated in brachycephalic dogs predisposed to bronchial diseases including bronchial collapse. The purpose of this study was to establish BA ratios for brachycephalic dogs and compare the values with those of non-brachycephalic dogs. Twenty-three brachycephalic dogs and 15 non-brachycephalic dogs without clinical pulmonary disease were evaluated. The BA ratio of the lobar bronchi in the left and right cranial as well as the right middle, left, and right caudal lung lobes was measured. No significant difference in mean BA ratio was observed between lung lobes or the individual animals (p = 0.148). The mean BA ratio was 1.08 +/- 0.10 (99% CI = 0.98~1.18) for brachycephalic dogs and 1.51 +/- 0.05 (99% CI = 1.46~1.56) for the non-brachycephalic group. There was a significant difference between the mean BA ratios of the brachycephalic and non-brachycephalic groups (p = 0.00). Defining the normal limit of the BA ratio for brachycephalic breeds may be helpful for diagnosing bronchial disease in brachycephalic dogs.

OBJECTIVE: To determine clinical features and diagnostic methods for primary tracheobronchial amyloidosis (TBA).
 METHODS: The clinical manifestations and diagnosis of a male patient who had been misdiagnosed for many years were described and analyzed.
 RESULTS: The patient was a 68-year-old male who complained of recurrent cough, expectoration, and progressive dyspnea for more than 30 years. He had been diagnosed with chronic bronchitis, bronchiectasis, and endobronchial tuberculosis in other hospitals and treated with antibiotics frequently and anti-tubercular agents for 3 months. Despite the treatments, the patient's symptoms were progressively worse. Finally, he came to Xiangya Hospital, Central South University, and was clearly diagnosed with primary TBA based on histopathological evidence after bronchoscopy.
 CONCLUSION TBA, a rare disease resulting from abnormal submucosal amyloid deposition in the trachea and bronchi, may display with many different symptoms. TBA is often misdiagnosed with other pulmonary diseases. The use of bronchoscopic techniques is essential for the diagnosis of TBA. Histopathology remains the gold standard for diagnosis of primary TBA. So, for patients with chronic cough of unknown etiology, bronchoscopy should be performed to obtain biopsy samples for the definitive diagnosis.
