  • Endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) now provides an important alternative diagnostic modality in patients with intrathoracic tuberculosis lymphadenopathy. The procedure is well tolerated in the outpatient setting, provides access to the mediastinal and hilar lymph node locations commonly in tuberculosis and also allows bronchial washing to be performed at the same procedure. However, there is no report of EBUS-TBNA applied to children to diagnose tuberculosis. We report a case of EBUS-TBNA applied to children who had intrathoracic tuberculosis lymphadenopathy.

  • A dog was presented with a cough, dyspnea, nasal discharge, gagging, and exercise intolerance. The dog showed leukocytosis, peripheral eosinophilia, and an increase C-reactive protein. The radiographic findings noted bronchointerstitial infiltration, intrathoracic lymphadenopathy, and soft tissue opacity mass. Computed tomography findings showed thickening of the bronchus and bronchiole. Also, peri-bronchial consolidation and generalized intrathoracic lymphadenopathy was present. On blind bronchoalveolar lavage and pulmonary cytology, there were significantly increased eosinophils. Canine pulmonary respiratory pathogens from a real-time polymerase chain reaction analysis was negative. Consequently, the dog was diagnosed with eosinophilic bronchopneumopathy. Clinical signs improved significantly within a few days after treatment with an oral corticosteroid.

  • Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a technique developed to allow mediastinal staging of lung cancer and also to evaluate intrathoracic lymphadenopathy. In a tuberculosis-endemic area, tuberculosis should be considered as an etiology of mediastinal lymphadenopathy. The aim of this study was to investigate the utility of the routine culture for tuberculosis from specimens of EBUS-TBNA. Methods: We prospectively performed routine culture for tuberculosis from aspiration or core biopsy specimens got from 86 patients who had undergone EBUS-TBNA due to mediastinal lymphadenopathy between March 2010 and March 2011. Results: A total of 135 lymph node aspiration and 118 core biopsy specimens were included in this analysis. We confirmed the malignancy in 62 (72.9%), tuberculosis in 7 (8.1%), sarcoidosis in 7 (8.1%), asperogillosis in 2 (2.3%) and pneumoconiosis in 2 (2.3%) patients. One lung cancer patient had pulmonary tuberculosis coincidentally and 5 patients had unknown lymphadenopathy. The number of positive culture for Mycobacterium tuberculsosis by EBUS-TBNA is 2 (1.5%) from 135 lymph node aspiration specimens and 2 (1.7%) from 118 core biopsy specimens. Out of eight patients confirmed with tuberculosis, only one patient had positive mycobacterial culture of aspiration specimen from EBUS-TBNA without histopathologic diagnosis. Conclusion: These results propose that routine culture for tuberculosis from EBUS-TBNA may not provide additional information for the diagnosis of coincident tuberculous lymphadenitis. However, if there is any possibility of tuberculous lymphadenopathy or pulmonary tuberculosis, it should be considered to perform EBUS-TBNA in patients who have negative sputum AFB smears or no sputum production.

  • Objectives: Careful evaluation about mediastinal involvement is important in the management of patients with non-small cell lung cancer. Invasive staging procedure such as mediastinoscopy is advocated because of the unreliability of noninvasive staging methods such as CT, MRI. We compared differences between pre- and postoperative staging in non-small cell lung cancer without lymphadenopathy on CT scan and investigated the methods for more accurate preoperative staging. Methods & Results: 1) Records of a total of 41 patients with preoperative $T_{1-3}N_0M_0$ non-small cell lung cancer were reviewed and the histologic types of tumors were squamous cell carcinoma in 32 cases, adenocarcinoma in 6 cases and large cell carcinoma in 3 cases. Twenty-four cases were central lesions and seventeen cases were peripheral lesions. 2) Among the 32 cases with preoperative $T_2$, 2 cases were identified postoperatively as $T_3$ with invasion of chest wall and among 6 cases with preoperative $T_3$, 1 case was identified postoperatively as $T_4$ with invasion of aorta and pulmonary arteries. 3) After the operation of 35 cases with $T_{1-2}$, 5 cases were $N_1$ and 3 cases were $N_2$ postoperatively. After the operation of 6 cases with $T_3$, 2 cases were $N_1$ and 3 cases were $N_2$ postoperatively. Preoperative $T_3$ showed more intrathoracic lymph node metastases and higher $N_2/N_1$ involvement ratio than preoperative $T_{1-2}$. 4) Complete surgical resections were done in 34 out of 41 cases. Incomplete resection were done in all postoperative $N_2$ tumors. Conclusion: Invasive staging procedures such as mediastinoscopy should be considered in the case of preoperative $T_3$ non-small cell lung cancer even though mediastinal lymphadenopathy is not recognized on the CT scan of the chest.

  • Purpose To identify the imaging features indicative of sarcoid-like reactions in patients with intrathoracic lymphadenopathy after complete remission of malignancies. Materials and Methods This study enrolled five patients with histopathologically confirmed sarcoid-like reactions that developed after cancer remission. The clinical features and findings of CT and 18F-fluorodeoxyglucose (FDG) PET/CT were assessed. Results The underlying malignancies included breast, nasopharyngeal, colon, and endometrial cancer and lymphoma. The time intervals between complete remission of malignancy and the diagnosis of sarcoid-like reaction ranged from 6 to 78 months. CT findings of sarcoid-like reaction included bilateral hilar and mediastinal lymphadenopathies (n = 5), pulmonary nodules (1-15 mm) with peribronchovascular, fissural, or subpleural distribution, and interlobular interstitial thickening in the lungs (n = 4). 18F-FDG PET/CT revealed hypermetabolic uptake in the mediastinal and hilar lymph nodes and both lungs in the absence of extrathoracic uptake (n = 3). The sarcoid-like reactions resolved in all patients after corticosteroid treatment. Conclusion In patients with complete remission of malignancies, newly developed bilateral hilar and mediastinal lymphadenopathies with or without pulmonary nodules of perilymphatic distribution, in the absence of recurrence at the primary tumor site and extrathoracic metastasis, may suggest a sarcoid-like reaction. Such cases warrant histologic evaluation of the lymph nodes to prevent unnecessary systemic chemotherapy.

  • Purpose : The risk of severe tuberculous disease such as meningitis or miliary tuberculosis increases as younger is the child at the time of infection. Therefore, the early diagnosis and prompt treatment is mandatory for infants with tuberculosis. This study was undertaken to describe the epidemiology, clinical and radiographic manifestations, and response to therapy in infants with tuberculous disease. Methods : Medical records of 29 infants with tuberculosis diagnosed at the Seoul National University Children's Hospital from July, 1985, to April, 1997, were reviewed, retrospectively. A case of tuberculosis was confirmed if M. tuberculosis was isolated from any body site or if there was histologic proof of tuberculosis. Otherwise, the diagnoses were individualized considering history of contact with contagious adult case, clinical manifestations, chest X-ray findings, result of a Mantoux test reaction with 5 tuberculin unit of PPD, and the response to therapy. Results : The mean age at diagnosis was $7.00{\pm}2.65$ months (range, 3 to 12 months). Twelve cases had isolated pulmonary diseases, and the rest had pulmonary disease and meningitis, 5 cases; pulmonary disease and cervical lymphadenitis, 3; isolated meningitis, 3; and miliary tuberculosis, 6. Source case was identified in 19 cases, 7 of which were detected with retrograde manner. Twenty seven of 29 were symptomatic at their initial visit. The presenting symptoms were mainly respiratory or neurologic, and respiratory difficulty was accompanied in 7 cases. Physical examination revealed wheezing in 7 cases and decreased breath sounds in 9. Hepatomegaly or hepatosplenomegaly were frequent. Chest radiographs showed lung parenchymal disease with hilar lymphadenopathy in 18 cases, and focal or generalized emphysematous change in 7 cases. Conclusion : Most of the infants with tuberculosis are symptomatic at diagnosis, and many of infants with intrathoracic tuberculosis presented with symptoms of bronchial obstruction. When tuberculosis is suspected in an infant, the adult source case should be vigorously investigated to aid in diagnosis and for the prevention of further transmission of tuberculous disease. Almost half of infant tuberculosis are preventable if prophylaxis were given when adult cases were diagnosed.
