RESUMO
CT-guided fine-needle aspiration biopsy of a metastasis from an ovarian cystadenocarcinoma was performed using air contrast and a transosseous approach. Air contrast allowed identification of a papillary projection within the cyst, and the transosseous approach permitted direct and easy access to the lesion.

This paper reviews our recent experience imaging glass and wooden foreign bodies of the extremities with magnetic resonance (MR) and CT. In all five cases the foreign bodies were detected by CT or MR or both. Only two of the foreign bodies were detected by plain radiography. Computed tomography and MR provided additional information regarding the adjacent tendons, neurovascular bundles, and muscle groups. The surrounding inflammatory reactions were accurately compartmentalized, and the extent of the disease along anatomic pathways of potential spread was demarcated. Magnetic resonance was superior to CT in soft tissue contrast resolution. Magnetic resonance and CT are not necessary for a case of acute foreign body injuries, but in complicated cases CT and MR may not only diagnose a foreign body but also serve to guide the surgical approach and extent of exploration.

We report a case of fibroblastic proliferation of the median nerve presenting as a focal mass. This report discusses the pathological and magnetic resonance correlations and reviews the differential diagnosis for median nerve masses.

Chronic patellar tendinitis can be a frustrating diagnostic and therapeutic problem. This report evaluates seven tendons in five patients with chronic patellar tendinitis. The etiologies included "jumper's knee" and Osgood-Schlatter disease. In all cases magnetic resonance images (MRI) showed thickening of the tendon. Some of the tendons had focal areas of thickening which helped establish the etiology. All cases had intratendinous areas of increased signal which, in four cases, proved to be chronic tendon tears. MRI is useful in evaluating chronic patellar tendinitis because it establishes the diagnosis, detects associated chronic tears, and may help determine appropriate rehabilitation.
