Five cases of clinically manifest solitary and bilateral renal lesions metastatic from the lung are presented. These cases are unusual in that renal metastases are usually silent lesions discovered at autopsy. Review of the autopsy data from this hospital identified renal metastases in 19% of patients who died from carcinoma of the lung. This incidence parallels that of other series. A solid renal lesion which is identified in a patient with a history of pulmonary carcinoma should raise the suspicion of renal metastases, especially if computed tomography of the mass demonstrates relative homogeneity and minimal enhancement. More frequent use of the abdominal CT scan in staging patients with lung cancer will render metastatic carcinoma from lung to kidney a more frequent ante mortem diagnosis.

Thirty patients are described on whom computed tomography was carried out because of endocrine ophthalmopathies. Fifteen patients had had the disease for more than two years, in the others it was acute. Determinations of muscle thickness and Hertel values show that there is no thickening of the extraocular muscles in patients with longstanding disease, but a significant increase in the Hertel values. Patients with recent disease show a definite increase in muscle thickness and corresponding protrusion of the globe, which can be explained by the changes in the muscles. The computer tomographic appearances of the striated ocular muscles in long-standing disease can be explained by fibrosis. These characteristics are of significance when considering the indications for radiation therapy.

The author describes a method of localizing nonpalpable breast lesions by transferring measurements from craniocaudal- and lateral-view radiographs to the breast itself in order to determine needle placement. In the more than 100 attempted cases, the lesion has been specifically localized, usually within 1 cm of the needle tip. Percutaneous biopsy can be carried out with the first needle used as a guide wire for the biopsy needle.
