Abstract An 18-year-old woman presented during the 2nd month of her pregnancy with noncommunicating hydrocephalus due to a cerebellar hemangioblastoma. The tumor rapidly enlarged over a 12-day period after ventriculoperitoneal shunting, probably because of expansion of the vascular compartment. Serial computed tomography and magnetic resonance imaging observations support previous speculations in the literature that vascular engorgement of hemangioblastomas probably accounts for the rapid deterioration of some patients during pregnancy.

We have developed a new X-ray microscope which produces complete three dimensional images of samples. The microscope operates by performing X-ray tomography with unprecedented resolution. Tomography is a non-invasive imaging technique that creates maps of the internal structure of samples from measurement of the attenuation of penetrating radiation. As conventionally practiced in medical Computed Tomography (CT), radiologists produce maps of bone and tissue structure in several planar sections that reveal features with 1mm resolution and 1% contrast. Microtomography extends the capability of CT in several ways. First, the resolution which approaches one micron, is one thousand times higher than that of the medical CT. Second, our approach acquires and analyses the data in a panoramic imaging format that directly produces three-dimensional maps in a series of contiguous stacked planes. Typical maps available today consist of three hundred planar sections each containing 512x512 pixels. Finally, and perhaps of most import scientifically, microtomography using a synchrotron X-ray source, allows us to generate maps of individual element.
