Case ReportsDetection of retroperitoneal hemorrhage by computed tomography.
Retroperitoneal hemorrhage can be directly documented by computed tomography. In patients with confusing clinical findings, CT scans may provide a definite diagnoses and direct appropriate therapy. This contention is supported by seven illustrative cases.

Several nonmalignant lymphoid disorders involve the lung parenchyma or the mediastinal or hilar lymph nodes. The pulmonary parenchymal lesions include lymphocytic interstitial pneumonitis, pseudolymphoma, and lymphomatoid granulomatosis. These disorders are generally not accompanied by lymph node enlargement. ⋯ An awareness of the distinction between these reactive disorders and lymphoma is important because the radiologic appearances may be similar. Histologic diagnosis is essential before treatment is initiated. With the exception of angioimmunoblastic lymphadenopathy and possibly of lymphadenitis, involvement of the pulmonary parenchyma associated with radiologic evidence of lymph node enlargement militates against the presence of any of these nonmalignant disorders.

Normal and abnormal upper abdominal venous structures as seen by ultrasound.
Recent B-scan ultrasonic techniques have made possible the routine visualization of the major upper abdominal venous structures. Real-time scanning permits in vivo dynamic assessment of the upper abdominal veins. B-scan ultrasound allows optimal anatomic resolution and is superior for the establishment of intraluminal pathology and anatomic relationships with adjacent organs. ⋯ Increased size of the upper abdominal venous structures can indicate certain pathological conditions, notably raised right heart pressure and portal hypertension. Intrinsic pathology within the inferior vena cava may be detected. Extrinsic distortion of veins by adjacent mass lesions is not uncommon, and if the venous structure is recognized, more precise anatomic localization of the mass is possible.

A case of pulmonary edema secondary to salicylate intoxication is described. The pulmonary wedge pressure was normal, excluding cardiogenic pulmonary edema. ⋯ The pulmonary edema resolved gradually over 8 days. Literature relative to salicylate-induced pulmonary edema is reviewed.

With the recent popularity of acupuncture therapy and anesthesia in the United States, patients are having temporary needles placed in the external ear. These matallic radiopaque needles appear on routine skull and mastoid examinations. This article is written to familiarize radiologists with this "new'' iatrogenic foreign body.
