Space Occupying Lesion

Plasma cell tumours of the mastoid are rare malignancies of haematological origin. Two patients are described with a plasma cell tumour in the mastoid bone. In one patient it concerned a solitary plasmacytoma of the bone and in the other a focus in the mastoid of a recently diagnosed multiple myeloma. Symptoms in these patients were non-specific. Computed tomography (CT) and magnetic resonance image (MRI) scanning showed a nonspecific space-occupying lesion in the mastoid. The diagnosis was made on immunohistological examination, that showed diffuse sheets of monoclonal plasma cells in a clear matrix. When a plasmacytoma lesion is found multiple myeloma should always be excluded. Treatment in case of solitary plasmacytoma of the mastoid bone consists of radiotherapy. In case of localization in the mastoid of multiple myeloma the treatment consists of palliative chemotherapy.

Luc’s abscess is a rare but important complication of acute otitis media (AOM), whereby infection spreads from the middle ear, resulting in a subperiosteal collection beneath the temporal muscle. Unlike other extracranial abscesses relating to AOM, Luc’s abscess is not believed to involve the mastoid bone. We present the case of a patient with a Luc’s abscess with mastoid involvement and discuss its successful management. We believe that patients presenting with a subperiosteal collection beneath the temporal muscle and mastoiditis may represent a different group of patients to those described originally by Luc. These individuals can be differentiated using computed tomography (CT) of the temporal bones. We advocate CT in patients with Luc’s abscess and AOM; this aids preoperative surgical planning.

Three Dimensional Images

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.
