Although neurofibromatosis type 1 (NF-1) is commonly considered neurocutaneous, severe arterial and venous abnormalities have been noted. Our patient, a 28-year-old woman, had bilateral giant extracranial aneurysms of the internal carotid arteries as well as skull base meningoceles involving the jugular foramina and aberrant jugular veins. CT and MR imaging, as well as digital subtraction and/or other angiography techniques, may be required to clarify pathology in patients with suggested vascular lesions.

We discuss the laser deposition rate of tungsten film, which saturates with increasing light intensity during photolysis of W(CO)(6) vapor. A new method for determining the absolute deposition rate is presented, and the results obtained are found to be quite close to those determined by the absorption method. We also present data showing how the deposition rate depends on other parameters.
