ReviewLymphoproliferative disorders of the lung: histopathology, clinical manifestations, and imaging features.
The lymphoproliferative disorders represent a spectrum of lymphoid abnormalities that can involve the chest. Plasma cell granuloma, pseudolymphoma, posttransplantation lymphoproliferative disorders, lymphoid interstitial pneumonia, and lymphomatoid granulomatosis involve the pulmonary parenchyma, whereas Castleman's disease, infectious mononucleosis, and angioimmunoblastic lymphadenopathy with dysproteinemia involve intrathoracic lymph nodes. Recent immunohistochemical techniques give us a better understanding of the lymphoproliferative disorders. Clinical and radiologic features often allow differentiation of the lymphoproliferative disorders from the more common aggressive lymphomas.

ReviewThe role of sonography in the placement and management of jugular and subclavian central venous catheters.
Placement of large-bore central venous catheters via a jugular or subclavian vein is becoming increasingly common. Although the great majority of these catheters are successfully placed by clinicians using anatomic landmark techniques, this procedure is neither innocuous nor always successful. ⋯ The patient may experience considerable discomfort when multiple needle passes are made. Sonographic imaging of the jugular and subclavian veins can significantly improve the safety, speed, and comfort of the procedure by defining the vascular anatomy of the jugular and subclavian veins before puncture, showing complications from prior attempts or placements of central venous catheters in these vessels, and providing guidance for needle puncture of the jugular and subclavian veins.
