Review of 11 cases of agenesis of the corpus callosum studied at our institution revealed a high incidence of associated anomalies. None patients had associated malformations of the central nervous system, 6 involving the pyramidal system. Eight cases were associated with malformations in the rest of the body. Review of completely examined cases from the literature yielded 47 examples of associated malformations. These were varied and without consistent pattern, with the possible exception of facial abnormalities.

During a 36-month period, seven cases of Horner's syndrome were encountered in a general pediatric hospital. The most common site of involvement was the ipsilateral sympathetic chain, although multiple sites were involved. Several causes of Horner's syndrome in childhood that have received little previous attention are reported-internal carotid artery thrombosis, subclavian artery aneurysm, and nasopharyngeal tumor. Suggestions for routine evaluation are given. Angiography and x-rays of the temporal and sphenoid bones are valuable in the diagnosis of intracranial lesions causing Horner's syndrome. Horner's syndrome is not rare in childhood and is associated with serious underlying disease.

This is a report of successful dilation of stenosis of the common trunk in a case of total anomalous pulmonary vein return into the left superior vena cava in a 3 month old infant. Percutaneous angioplasty was performed with a 6 mm diameter balloon catheter. Right ventricular systolic pressure decreased from 96 to 60 mm Hg, mean pulmonary vein pressure decreased from 26 to 14 mm Hg and left ventricular systolic pressure increased from 70 to 90 mm Hg.
