We described two patients with heterotopic pregnancy. In one patient the transabdominal sonographic findings were non-specific and laparoscopy was required for diagnosis. In the second patient transabdominal sonographic findings suggested a diagnosis of heterotopic pregnancy. Endovaginal sonography confirmed this by allowing visualization of the live extrauterine gestation.

Neurologic involvement is common in patients with acquired immune deficiency syndrome (AIDS). To assess the computed tomographic findings in AIDS, the authors reviewed 12 consecutive patients found to have focal brain lesions representing AIDS complications on computed tomography and having histologic or clinical proof of the diagnosis. Five patients had toxoplasmosis, six had lymphoma and one had both conditions sequentially. The finding of multiple lesions and mass effects with edema was more common with toxoplasmosis. In six patients who had toxoplasmosis 33 nodules were observed compared with only 8 in seven patients who had lymphoma. Disease extending linearly along the ventricular wall was typically seen in patients who had lymphoma.

Thirteen chest radiographs and computed tomographic (CT) scans obtained from 11 patients with hypersensitivity pneumonitis were reviewed. The CT findings were correlated with open lung biopsy findings in seven patients. The two patients with acute hypersensitivity pneumonitis showed air-space opacification on CT scans. An open lung biopsy, done in one of these patients, demonstrated noncaseating granulomas and filling of the air spaces with macrophages. The nine patients with subacute hypersensitivity pneumonitis showed small, rounded opacities and patchy air-space opacification on CT scans. These findings reflected the histologic findings, which consisted of interstitial pneumonitis, cellular bronchiolitis, and small, noncaseating granulomas. The six patients with symptoms for 12 months or longer also showed irregular linear opacities on CT scans, corresponding to areas of fibrosis. CT scans were superior to radiographs in helping to assess the type and extent of abnormalities, and high-resolution CT scans were superior to conventional CT scans.
