ABSTRACT
A 34-year-old man with neurofibromatosis type 1 (von Recklinghausen's disease) was examined by 201TlCl and 99mTc-tetrofosmin scintigraphies. Hypervascularity was observed in the largest tumor of the right thigh. The tumor was also depicted on both scintigrams. Tumorectomy was performed and the pathologic examination revealed it to be a neurofibroma measuring 10 x 7 x 4 cm in size. These findings suggested that 201TlCl and 99mTc-tetrofosmin scintigraphies generally were unable to distinguish malignant from benign neurofibromas with certainty.

Sudden cardiac death is the major cause of death in the United States today, claiming over 400,000 victims each year, or one per minute. In the majority of cases, the underlying mechanism is malignant ventricular tachyarrhythmia, with the common substrate being abnormal myocardium from ischemic heart disease or congestive cardiomyopathy.

Angioplasty is most commonly performed with catheters introduced percutaneously into the femoral artery. A brachial approach has previously been described that employs arteriotomy and cutdown. We describe here the technique and initial results of an alternative method of brachial entry, wherein the catheter is introduced percutaneously. Angioplasty has been performed in 26 patients in this manner, without complications.
