A prospective study including seventy-seven consecutive patients suspected of having ovarian tumoral or pseudotumoral pathology on CT was carried out. Fifty-nine patients had surgery with histological diagnosis. When comparing the CT and histological findings in benign and malignant lesions we obtained an overall accuracy of 95% with only three misdiagnosed cases on CT. False positive diagnosis of malignancy was established in a case of abdominal actinomycotic infection, a case of chronic appendicitis, and in a ruptured ectopic pregnancy. These three cases are discussed in detail.

Six scapulohumeral joints (3 normal joints and 3 joints with radiographic evidence of osteochondrosis) underwent conventional magnetic resonance (MR) imaging and MR scapulohumeral arthrography to evaluate delineation of the articular cartilage. The MR arthrography was performed, using 5 ml of 500 microM gadopentetate dimeglumine (Gd-DTPA) as a contrast medium. Delineation of normal articular cartilage and cartilage defects was less accurate after intra-articular administration of Gd-DTPA. Therefore, it was concluded that MR arthrography with Gd-DTPA is unrewarding for evaluation of osteochondrosis lesions.
