This is a retrospective study of 106 ovarian neoplasms, all of which were surgically removed and had preoperative sonographic examinations. The objec tive of this study was to determine if sonography could differentiate malignant and benign tumors and if it could determine the specific histology of a tumor.Ovarian carcinoma accounts for 25% of all gynecologic cancer and causes 47% of all deaths due to gynecologic cancer. It is most common after menopause, with the average age being 62 years. The poor prognosis of this tumor is due largely to the fact that patients remain asymptomatic until there is metastatic disease; 60%-70% of the patients are stage III or IV at the time of diagnosis. The most common early symptoms are vague gastrointestinal complaints. This is such a salient feature of the early symptom complex that ovarian carcinoma must be included in the differential diagnosis of postmenopausal patients with gastroin testinal complaints [1 -3]. Most malignant tumors discussed here were advanced at the time of discovery. However, some were seen at a relatively early stage when these tumors would be potentially curable.

The authors reviewed all cases of acquired immunodeficiency syndrome (AIDS)-related lymphoma (ARL) seen at their institution between January 1982 and September 1988 to determine the frequency and appearance of ARL in the chest. Of 35 patients with ARL, 11 (31%) had biopsy-proved thoracic involvement. This frequency is significantly greater than that previously reported. The radiologic appearance of the thoracic involvement varied. Pleural effusion, interstitial and alveolar lung disease, nodules, and, infrequently, hilar and mediastinal adenopathy were observed. ARL of the chest was most commonly extranodal. Pleural effusion and lung disease were the two most common manifestations of ARL on chest radiographs and computed tomographic scans. The authors recommend that clinicians treating patients with suspected or known AIDS consider ARL when a pleural effusion or a noninfective interstitial or alveolar process is present.
