BACKGROUND AND PURPOSE: Internal target motion results in geometrical uncertainties in lung cancer radiotherapy. In this study, we determined the intrafraction motion and baseline shifts of mediastinal lymph node (LN) targets between setup imaging and treatment delivery. MATERIAL AND METHODS: Ten lung cancer patients with 2-4 fiducial markers implanted in LN targets received intensity-modulated radiotherapy with a daily setup cone-beam CT (CBCT) scan used for online soft-tissue match on the primary tumor...

Congenital Lobar Emphysema (CLE) is a developmental anomaly, characterized by hyperinflation of one or more pulmonary lobes. It presents in infancy with variable degree of respiratory distress due to compression atelectasis. It is most often associated with mediastinal shift with subsequent hypoxia. CLE poses a diagnostic and therapeutic dilemma. We report a case of five-month-old infant of CLE requiring left lobectomy, who was previously being treated for pneumonia which was unresponsive to medical therapy...

Necrosis of the fat adjacent to the heart, referred to as pericardial fat necrosis, epipericardial fat necrosis, and mediastinal fat necrosis, is a rare, self-limited condition. It presents as a sudden onset of severe chest pain that mimics symptoms of pulmonary embolism and acute coronary syndrome. Computed tomography (CT) findings are quite typical and consist of a round- or oval-shaped mass-like lesion containing soft tissue and fat density components in the cardiophrenic space. Lack of familiarity with this condition has led in the past to surgical interventions to remove the mass-like mediastinal fat necrosis...

BACKGROUND: Sarcoidosis is a granulomatous disease of unknown etiology. Macrophages play a key role in granuloma formation with the T cells, having a significant impact on macrophage polarization (M1 and M2) and the cellular composition of the granuloma. This study evaluates macrophage polarization in granulomas in pulmonary sarcoidosis. MATERIALS AND METHODS: Tissue specimens from the Department of Pathology biobank at the Masih Daneshvari Hospital were obtained...

The shift from open to minimally invasive techniques in thoracic surgery has been dramatic during the past 10 years. Not only the feasibility, safety, reproducibility and oncologic efficacy of these techniques have been clearly demonstrated, but also their superiority concerning mortality, postoperative pain, postoperative quality of life and recovery. Thus, video-assisted thoracic surgery (VATS) is currently the procedure of choice for a wide variety of thoracic interventions, ranging from major pulmonary resections for lung cancer to thymectomy and mediastinal procedures, even to esophageal procedures...

Ductal origin of pulmonary artery is a rare anomaly that is frequently misdiagnosed. Patients may present with exertional dyspnoea, recurrent respiratory infections and pulmonary hypertension. The presence of pulmonary hypertension can adversely affect clinical outcome in these patients; hence, early identification and intervention is the key to improve survival. A case of a 3-year-old child presenting with exertional dyspnoea is presented in this report. Chest radiograph revealed right-sided pulmonary hypoplasia and mediastinal shift to the right...

A 3-year-old Himalayan cat was presented with respiratory distress. Radiography showed multiple gas opacity foci, with the locations dependent on patient positioning, and severe pleural effusion with a contralateral mediastinal shift. A large volume of fluid and air was aspirated, and the fluid components were consistent with a nonseptic exudate. A pulmonary mass, pleural nodules, and an air-fluid interface with air bubbles trapped in fibrous septations were identified using thoracic ultrasonography and CT...

Adenoid cystic carcinoma is a very rare malignancy commonly originating from the salivary glands of the head and neck. It is again very scantily seen in sites like the bronchus. Surgical resection is the mainstay of treatment but many a times the tumour site and size preclude a favourable outcome of surgery and the patient is advised for other forms of local treatment like Radiotherapy. Here, we present a case report of a young female with primary adenoid cystic carcinoma of the bronchus. The tumour was located in the carina and the left bronchus which was obstructing the airway resulting in collapse of the left lung, this resulted in shifting the mediastinum and abdominal structures in to the thorax...

PURPOSE: Secondary spontaneous pneumothorax (SSP) is difficult to treat by itself and due to its association with serious underlying diseases. It has a high rate of recurrence and often requires extended hospitalization. Therefore, we evaluated the outcome and risk factors associated with recurrence and extended hospitalization. METHODS: We retrospectively examined 61 patients with SSP, and evaluated the patients' characteristics, underlying diseases, introduction of home oxygen therapy, Brinkman index, and X-ray imaging findings to determine the risk factors for recurrence and extended hospitalization...

Sudden death due to diaphragmatic hernia in an adult is exceptionally rare. A 43-year-old man was found dead by his cohabiting mother, lying supine on the floor in his house. He had complained of epigastric discomfort for 1 month, and respiratory symptoms occurred 1 day before his death. He had no history of trauma. Postmortem computed tomography scan revealed the enlarged fluid-filled stomach herniated into the left pleural cavity, compressing the left lung with a mediastinal shift to the right. At autopsy, the left pleural cavity was occupied by herniated abdominal contents with mediastinal shift...

BACKGROUND: Bronchial carcinoid tumors (BCTs) are rare neuroendocrine neoplasms of the lung that mainly have a central distribution. They are classified as typical and atypical, with the former variant generally conferring a more favorable survival. Central tumors are usually symptomatic with features of bronchial obstruction, whereas peripheral tumors may remain silent. CASE REPORT: A 36-year-old woman presented to our hospital due to an episode of massive hemoptysis 5 days prior to admission...

The aims of chest drainage after pulmonary resection are to evacuate fluid and air that accumulate in the pleural space and to obtain information on problems such as air leakage and postoperative bleeding. Although suction or water seal drainages are commonly used procedures, the use of digital monitoring system (Thopaz) is gaining popularity as an alternative of the procedures. We need to pay attention to postoperative hemorrhage, chylothorax, infection, and air leakage. Chest X-ray is essential to check the position of the drainage tube and lung expansion...

Following a pneumonectomy, excessive mediastinal shift can cause rare complications involving the post-pneumonectomy cavity, which can become the seat of herniation of the residual lung and of the heart. We herein report an even more rare event, entailing an impressive herniation of the actual entire post-pneumonectomy cavity through an intercostal space, which developed spontaneously nearly 3 years after surgery. Surgical excision of the hernia sac and repair of the defect with polypropylene mesh provided adequate treatment and good cosmetic results...

Described here are a series of four cases of congenital high airway obstruction in the fetus. All of the patients presented in the second trimester and all had hydrops fetalis. Three cases had bilateral hyperinflated lungs, midline shift of heart, flattening or inversion of the diaphragm, and fetal ascites. Autopsy was performed in one of these three and showed laryngeal atresia. In one fetus, there was only a unilateral huge enlargement of the lung with mediastinal shift. On autopsy, this fetus had atresia of right main bronchus...

OBJECTIVES: In the 7th edition of the tumour, node and metastasis staging system, a primary tumour size larger than 5 cm was shifted to Stage II. Therefore, we aimed to evaluate the characteristics and prognostic factors of node-negative non-small cell lung cancer (NSCLC) larger than 5 cm. METHODS: We included 109 patients who underwent curative resection and had pathologically confirmed node-negative NSCLC >5 cm (Group 1). We compared the clinicopathological characteristics and prognosis of these patients with 85 patients with node-positive NSCLC >5 cm (Group 2) and 383 patients who had node-positive NSCLC ≤5 cm (Group 3)...
