The CT aspect of thoracic gossypiboma may be different according to pleural or parenchymal location. The spongiform appearance, characteristic in abdominal gossypiboma, is not the only CT presentation of thoracic gossypiboma. The confrontation of the surgical history with the CT signs helps to have a preoperative diagnosis.
Castleman's disease (CD) is an uncommon, mainly benign, lymphoproliferative disorder of unknown etiology, mostly involving the mediastinum. Parenchymal lung involvement of the disease is exceedingly rare. We describe a case of CD in a 23-year-old woman with a 4-year history of recurring dyspnea and nonproductive cough, whose chest X-ray showed an abnormal shadow of the right hilum. Chest computed tomography confirmed the presence of a tissue-density mass of the right lower lobe, demonstrating poor contrast enhancement, associated with multiple laterotracheal and mediastinal lymphadenopathies. The patient underwent curative surgery, revealing a right hilar compressive mass, with an intrafissural development between the superior and middle lobes. Pneumonectomy was performed due to profuse bleeding. This case of CD is particular because of its unusual intrapulmonary location and its intrafissural development. Poor contrast enhancement is atypical in CD.
Paragangliomas of the mediastinum are rare neoplasms, representing less than 0.3% of mediastinal tumours and less than 2% of all paragangliomas. To date, no definitive morphologic criteria exist that correlate with the clinical outcome of these tumours. This report describes three patients with peculiar primary paragangliomas of the posterior mediastinum: gangliocytic, dumbbell and functional paraganglioma. The clinicopathological characteristics of these patients are presented and the literature reviewed.
Background: This study aimed to compare paravertebral block and continuous intercostal nerve block after thoracotomy. Methods: Forty-six adult patients undergoing elective posterolateral thoracotomy were randomised to receive either a continuous intercostal nerve blockade or a paravertebral block. Opioid consumption and postoperative pain were assessed for 48 hours .Pulmonary function was assessed by forced expiratory volume in 1 s (FEV1) recorded at 4 hours intervals. Results: With respect to the objective visual assessment (VAS), both techniques were effective for post thoracotomy pain. The average VAS score at rest was 29±10mm for paravertebral block and 31.5±11mm for continuous intercostal nerve block. The average VAS score on coughing was 36±14mm for the first one and 4 ±14mm for the second group. Pain at rest was similar in both groups. Pain scores on coughing were lower in paravertebral block group at 42 and 48 hours. Post-thoracotomy function was better preserved with paravertebral block. No difference was found among the two groups for side effects related to technique, major morbidity or duration of hospitalisation. Conclusion: We found that continuous intercostal nerve block and paravertebral block were effective and safe methods for post-thoracotomy pain.
Lymphoid granulomatosis is a rare form of pulmonary angiitis. This case report presents a patient with lymphoid granulomatosis in whom the clinical presentation, radiological features and the partial response to corticosteroid therapy mimicked interstitial lung disease. Lymphoid granulomatosis was only diagnosed at post-mortem examination. The range of reported clinical presentations, diagnostic approaches and outcomes are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
