Chest “Tightness” in an Elderly Woman
A 76-year-old woman presents with chest pain—which she describes as “muscle tightness”that began when she awoke in the morning. The pain is constant, exacerbated by deep inspiration, and accompanied by a subjective sense of slight dyspnea; she rates its severity as 3 on a scale of 1 to 10. She denies pain radiation, nausea, diaphoresis, palpitations, and light-headedness. Her only cardiac risk ...
متن کاملMediastinal widening on chest radiography caused by combined aortic valve disease and primary large B-cell lymphoma
Poststenotic aortic root dilatation in patients with aortic valvular stenosis may result in mediastinal widening on chest radiograph. Main differential diagnosis of mediastinal widening is a tumour. In fact, besides atypical chest pain or dyspnoea at exertion secondary to compression of intrathoracic structures in the latter, symptoms may be absent. We report a case of combined aortic valve dis...
متن کاملMediastinal biopsy for indeterminate chest lesions.
The current literature contains numerous reports on the importance of the mediastinal lymph nodes in the diagnosis and prognosis of pulmonary neoplasms. We recently described a technique by which the mediastinal contents could be explored directly with little risk (Stemmer, Calvin, Chandor, and Connolly, 1965). Figure 1 illustrates the operative technique. An oblique incision is made just later...
متن کاملMediastinal and Chest Wall Masses in Children: A Single Institution Study
Background and Objective: Mediastinal masses in children are a heterogenous group of asymptomatic potentially life-threatening congenital, infectious, or neoplastic lesions that present complex diagnostic and therapeutic dilemmas. Materials and Methods: The clinical and laboratory features of 65 patients...
متن کاملMediastinal and chest wall limitations to asymmetry of lung inflation.
The extent to which inflation of one lung increases pleural pressure around the contralateral lung could affect ventilatory function, e.g., after pneumonectomy or lung transplantation. The rise in contralateral pleural pressure is limited by mediastinal stiffness and other chest wall properties. To estimate these properties, we determined an elastance of asymmetric expansion (E(Asym)) in 20 sup...
