Sarcoidosis is a granulomatous disease of unknown etiology. At present the best diagnostic imaging procedure to assess stage and activity of sarcoidosis is controversial. We report the case of a 50-year-old male admitted with a history of dyspnea and fatigue with past medical history negative for smoking, occupational and environmental risk factors. Physical examination, routine blood tests, and pulmonary function tests were normal except for hypercalciuria. A chest radiograph showed bilateral hilar lymphadenopathy. Single photon emission computed tomography and/or computed tomography (SPECT and/or CT) In-111 Octreotide (Octreoscan) scintigraphy confirmed morphologic involvement of bilateral hilar lymph nodes and a mediastinoscopy biopsy specimen provided diagnosis of pulmonary sarcoidosis (stage 0). This clinical case shows the effectiveness of In-111 Octreotide SPECT and/or CT in the early diagnosis of pulmonary sarcoidosis.

Review
In potentially resectable non-small cell lung cancer (NSCLC) accurate mediastinal staging is crucial not only to offer the optimal management but also to avoid unnecessary surgery. Mediastinal staging is generally performed by the use of imaging techniques (computed tomography and positron emission tomography). However, the accuracy of radiological imaging in mediastinal staging is suboptimal. Therefore, additional invasive mediastinal staging is frequently required to select patients who can benefit from a neoadjuvant treatment. In recent years, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has progressively replaced mediastinoscopy as a test for invasive mediastinal staging. The considerable potential of EBUS-TBNA as minimally invasive staging method has been understood by pulmonologists since the early 2000s but only recently by thoracic surgeons. The clinical impact of this diagnostic technology has been broadly highlighted in the literature and EBUS-TBNA is currently considered the test of first choice in preoperative nodal staging of NSCLC. We analyze the actual role of EBUS-TBNA in invasive mediastinal staging of NSCLC patients from the thoracic surgeon point of view, with particular emphasis on the performance characteristics of this endoscopic diagnostic method as well as its clinical use within the published guidelines.

We present the case of a healthy young woman who consulted for left peripheral facial palsy associated with fever, dry cough, dyspnea, and asthenia of two weeks' evolution. Physical examination revealed hypoesthesia in left T6 to T12 dermatomes and bilateral galactorrhea. In the laboratory, she presented negative viral serology, elevated erythrocyte sedimentation rate, antinuclear antibody titers, prolactin and thyroid-stimulating hormone, with positive antiperoxidase antibodies. Computed tomography showed multiple bilateral cervical, mediastinal, and hilar adenopathies, without involvement of lung parenchyma. Cerebrospinal fluid culture was negative for common germs, mycobacteria, and Xpert MTB/RIF, and cytology did not show atypia. Contrast-enhanced magnetic resonance was performed on the brain without pathological findings and on the spine with alteration of the centromedullary signal from T6 to T9 of almost the entire thickness of the cord, with posterior enhancement with gadolinium. During hospitalization, she recovered sensitivity in the left trunk and did not repeat febrile or cough episodes. She was referred to another center for mediastinoscopy with lymph node biopsy revealing the presence of numerous non-caseating granulomas compatible with sarcoidosis. It was classified as probable neurosarcoidosis and started treatment with corticosteroids with improvement of the remaining neurological symptoms. A magnetic resonance was performed three months later where the signal alteration was limited from T7 to T8. Our objective is to highlight the florid neurological presentation that made it necessary to rule out other more frequent entities and the favorable evolution even before starting a first-line scheme of treatment.

A 53-year-old African American male smoker presented with epigastric pain, tarry stools, and laboratory results indicative of acute pancreatitis. Chest X-ray showed a right perihilar mass with pleural effusion. Computed tomography scan showed multiple large right paratracheal and hilar nodes with internal calcification. The patient underwent a fiberoptic bronchoscopy with biopsies which were negative for malignancy. Mediastinoscopy was performed and revealed amyloidosis. Evaluation for multiple myeloma showed elevated kappa and lambda light chains and diffuse polyclonal gammopathy, but there was no monoclonal spike on serum protein electrophoresis. Bone marrow and abdominal fat pad were negative for amyloid, and the patient continues to lack chronic underlying systemic disease with no symptoms on cardiac or pulmonary examination.

BACKGROUND AND OBJECTIVE
To evaluate the diagnostic accuracy and clinical usefulness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for mediastinal staging of centrally located T1N0M0 non-small cell lung cancer (NSCLC) clinically staged with positron emission tomography/computed tomography (PET/CT).
METHODS
We conducted a study that included patients with centrally located T1N0M0 NSCLC, clinically staged with PET/CT who underwent EBUS-TBNA for mediastinal staging. Patients with negative EBUS-TBNA underwent mediastinoscopy, video-assisted mediastinoscopic lymphadenectomy (VAMLA) and/or lung resection with systematic nodal dissection, that were considered the gold standard. The sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), overall accuracy of EBUS-TBNA for diagnosing mediastinal metastases (N2 disease) and the number needed to treat (NNT: number of patients needed to undergo EBUS-TBNA to avoid a case of pathologic N2 disease after resection) were calculated.
RESULTS
One-hundred eighteen patients were included. EBUS-TBNA proved N2 disease in four patients. In the remaining 114 patients who underwent mediastinoscopy, VAMLA and/or resection there were two cases of N2 (N2 prevalence 5.1%). The sensitivity, specificity, NPV, PPV and overall accuracy for diagnosing mediastinal metastases (N2 disease) were of 66%, 100%, 98%, 100% and 98%, respectively. The NNT was 31 (95% CI: 15-119).
CONCLUSION
EBUS-TBNA in patients with central clinically staged T1N0M0 NSCLC presents a good diagnostic accuracy for mediastinal staging, even in a population with low prevalence of N2 disease. Therefore, its indication should be considered in the management of even these early lung cancers.

BACKGROUND
Mediastinal lymph node metastases (MLNM) are not rare in thyroid cancer, but their treatment has not been extensively studied. This study aimed to explore the preliminary application of video mediastinoscopy-assisted superior mediastinal dissection in the diagnosis and treatment of thyroid carcinoma with mediastinal lymphadenopathy.
MATERIALS AND METHODS
We retrospectively reviewed the clinical pathologic data and short-term outcomes of thyroid cancer patients with suspicious MLNM treated with video mediastinoscopy-assisted mediastinal dissection at our institution from 2017 to 2020.
RESULTS
Nineteen patients were included: 14 with medullary thyroid carcinoma and five with papillary thyroid carcinoma. Superior mediastinal nodes were positive in nine (64.3%) patients with medullary thyroid carcinoma and in four (80.0%) patients with papillary carcinoma. No fatal bleeding occurred. There were three cases of temporary recurrent laryngeal nerve (RLN) palsy postoperatively, one of which was bilateral. Four patients had temporary hypocalcemia requiring supplementation, one had a chyle fistula, and one developed wound infection after the procedure. Postoperative serum molecular markers decreased in all patients. One patient died of cancer while the other 18 patients remained disease-free, with a median follow-up of 33 months.
CONCLUSION
Video mediastinoscopy-assisted superior mediastinal dissection can be performed relatively safely in patients with suspicious MLNM. This diagnostic and therapeutic approach may help control locoregional recurrences.

EBUS-TBNA is an integral tool in the diagnosis and staging of lung cancer and other diseases involving mediastinal lymphadenopathy. Most studies attesting to the performance of EBUS-TBNA are prospective analyses performed under strict protocols. The objective of our study was to compare the accuracy of EBUS-TBNA to surgery in diagnosing hilar and mediastinal pathologies in a tertiary hospital, staffed by pulmonologists with and without formal interventional pulmonary training. We retrospectively analyzed subjects who underwent EBUS-TBNA followed by a confirmatory surgical procedure from January 2012 to December 2018. The primary outcome was to evaluate the accuracy of EBUS-TBNA in the diagnosis of all mediastinal disease. Secondary analyses determined the accuracy of EBUS-TBNA in cancer, NSCLC, and non-malignant lesions individually. One hundred and forty-three subjects had an EBUS-TBNA procedure followed by surgery. EBUS-TBNA for all pathologies had an accuracy of 81.2% (CI 95% 73.8-87.4) and sensitivity of 55.1% (CI 95% 41.5-68.3). The accuracy and sensitivity of individual groups were: cancer (81.7, 48.8%), NSCLC (84, 48.3%), and non-malignancy (78.9, 60%). The NSCLC group had 15 false negatives and 5 (33.3%) of them were due to non-sampling of EBUS accessible nodes. Missed sampling led to a change in the final staging in 8.6% of NSCLC subjects. The accuracy of EBUS-TBNA across all groups was comparable to those reported previously. However, the sensitivity was comparatively lower. This was primarily due to the large number of EBUS-TBNA accessible lymph nodes that were not sampled. This data highlights the need for guidelines outlining the best sampling approach and lymph node selection.

To summarize the clinical manifestations and treatment of patients with deep neck infection with descending mediastinal infection. The clinical data of 12 patients with deep neck infection with descending mediastinal infection were reviewed. The clinical manifestations, infection origin, bacterial culture results, related systemic diseases, surgical drainage methods and treatment results were analyzed. The typical clinical features of descending mediastinal infection were chest pain and subcutaneous crackling, diagnosis can confirmed by CT scan detected gas and abscess in the neck and mediastinal space. The main origin of infection was pharyngeal infection, followed by odontogenic infection. Systemic diseases were mainly diabetes mellitus. The positive rate of purulent secretion culture was 58.3%(7/12), streptococcus account for the highest proportion. Surgical treatment included 9 patients undergoing neck surgery alone and 3 patients undergoing combined neck and chest surgery. Chest drainage was performed by thoracic surgery through mediastinoscopy or thoracoscopic surgery or B-ultrasound guided puncture, and no patient underwent open surgery. Ten patients were cured and two died, with a mortality rate of 16.7%. The deep neck infection with descending mediastinal infection has no specificity in the early stage. Timely abscess drainage, effective airway protection, antimicrobial therapy, and management of potentially life-threatening complications such as sepsis, mediastinitis, and pneumonia are the key to successful treatment.

BACKGROUND
Large cell neuroendocrine carcinoma of the lung (LCNEC) is a rare entity occurring in less than 4% of all lung cancers. Due to its low differentiation and high glucose transporter 1 (GLUT1) expression, LCNEC demonstrates an increased glucose turnover. Thus, PET/CT with 2-[F]-fluoro-deoxyglucose ([F]FDG) is suitable for LCNEC staging. Surgery with curative intent is the treatment of choice in early stage LCNEC. Prerequisite for this is correct lymph node staging. This study aimed at evaluating the diagnostic performance of [F]FDG PET/CT validated by histopathology following surgical resection or mediastinoscopy. N-staging interrater-reliability was assessed to test for robustness of the [F]FDG PET/CT findings.
METHODS
Between 03/2014 and 12/2020, 46 patients with LCNEC were included in this single center retrospective analysis. All underwent [F]FDG PET/CT for pre-operative staging and subsequently either surgery (n = 38) or mediastinoscopy (n = 8). Regarding the lymph node involvement, sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) were calculated for [F]FDG PET/CT using the final histopathological N-staging (pN0 to pN3) as reference.
RESULTS
Per patient 14 ± 7 (range 4-32) lymph nodes were resected and histologically processed. 31/46 patients had no LCNEC spread into the lymph nodes. In 8/46 patients, the final stage was pN1, in 5/46 pN2 and in 2/46 pN3. [F]FDG PET/CT diagnosed lymph node metastasis of LCNEC with a sensitivity of 93%, a specificity of 87%, an accuracy of 89%, a PPV of 78% and a NPV of 96%. In the four false positive cases, the [F]FDG uptake of the lymph nodes was 33 to 67% less in comparison with that of the respective LCNEC primary. Interrater-reliability was high with a strong level of agreement (κ = 0.82).
CONCLUSIONS
In LCNEC N-staging with [F]FDG PET/CT demonstrates both high sensitivity and specificity, an excellent NPV but a slightly reduced PPV. Accordingly, preoperative invasive mediastinal staging may be omitted in cases with cN0 disease by [F]FDG PET/CT. In [F]FDG PET/CT cN1-cN3 stages histological confirmation is warranted, particularly in case of only moderate [F]FDG uptake as compared to the LCNEC primary.

BACKGROUND
Mantle cell lymphoma (MCL) is a subtype of Non-Hodgkin's lymphoma (NHL). MCL frequently affects extranodal sites while endobronchial involvement is uncommon. Only 5 cases of MCL with endobronchial involvement have been previously reported.
CASE SUMMARY
A 56-year-old male patient arrived at the hospital complaining of a dry cough. A mass in the right upper lobe of the lung was revealed in Chest computed tomography (CT). Right lung hilar and mediastinal lymphadenopathies were also found by CT scan. The patient was diagnosed with central-type lung cancer with multiple lymph node metastases after positron emission tomography (PET) CT scan examination. The fiber optic bronchoscope examination revealed diffuse neoplasm infiltration in the inlet of the right up lobar bronchus. The patient was finally diagnosed with MCL based on the bronchoscopy and mediastinoscopy biopsy results.
CONCLUSION
MCL could masquerade as central type lung cancer. An endobronchial biopsy examination is necessary for the early diagnosis of MCL.
