Forty-eight patients with proven disease of the salivary glands were evaluated by computed tomography (CT). Twenty-seven patients had salivary gland neoplasm and all were identified by CT. Fifteen benign tumors appeared as discrete, sharply marginated, high-density masses embedded in an otherwise normal gland.

Evaluation of current techniques for nonsurgical removal of intravascular iatrogenic foreign bodies.

Intravascular embolization of polyethylene catheter fragments continues to occur, the majority from intravenous indwelling catheters. Sixty-nine nonsurgical retrievals of embolized fragments have been reported. The various recorded retrieval techniques are reviewed as well as their respective successes and limitations.
