Staging was undertaken in 118 patients with primary lymph node neoplasms; the sensitivity of computer tomography in the paraaortic region was 80%, that of lymphography 89%. Specificity of computer tomography was 93%, of lymphography 95%. In the iliac region, sensitivity was 81% (CT) and 90% (lymphography), and specificity was 90% (CT) and 97% (Lymphography). The value of computer tomography should, however, be stressed, since it can demonstrate lymph nodes not shown by lymphography, including those in the mediastinum, as well as lesions in the spleen, liver and lungs.

SuMMARY This report describes the diagnosis of a false left ventricular aneurysm by echocardiography and pulsed Doppler echocardiography. The patient successfully underwent resection of the pseudoaneurysm.

One hundred and thirty examinations with oral gastrografin were performed in 110 patients with obstructive symptoms, who did not require immediate operation. They consisted of 49 patients with mechanical ileus, eighteen patients with paralytic ileus and 63 patients with incomplete mechanical ileus. All patients with complete mechanical and three patients with paralytic ileus were investigated surgically and treated in this way. Small bowel transit time longer than five hours provides considerable certainty of complete mechanical ileus. The method has been tried for four years; it makes few demands on the patient and has practically no contra-indications, except for deranged electrolyte balance. In children, the amount of contrast medium should be limited and it should be diluted or an isotonic contrast medium should be used. The method provides definite differentiation between mechanical and functional obstruction. In patients with adhesions and recurrent incomplete obstruction, further laparotomies may be avoided in this way.

The clinical significance of varicoceles depends on their frequency and on the fact that they may produce infertility. The available operative forms of treatment are unsuccessful in about 10% of patinents. In these cases it is desirable to elucidate the very variable drainage pattern by means of transfemoral phlebography with the patient erect. The method was employed in 13 patients and demonstrated continuity of the testicular vein, or of one of its tributaries, in twelve. If the testicular vein appears to be absent, one must consider the possibility of a venous short circuit or drainage of the pampiniform plexus into the external iliac vein. In four patients out of the 13, scrotal phlebography in addition for complete definition was necessary.
