Management of nonsmall cell lung carcinoma with solitary brain metastasis.

Cushing's group, operating on metastatic brain tumors in the 1920s, was the first to point out that lung cancer (usually adenocarcinoma in an upper lobe) was the most common primary tumor. Excision of a solitary metastasis could result in long-term survival. Magilligan and coworkers (J Thorac Cardiovasc Surg 1976;72:690) introduced the modern era of large series of combined lung-brain resection with low mortality (3%) and a 5-year outcome of 21%.

Computed tomographic discography in the evaluation of extreme lateral disc herniation.

Thin section, high resolution computed tomographic (CT) scans of the lumbar spine produce images that can show herniated intervertebral discs without intravenous or intrathecal contrast enhancement. With this technique, the diagnosis of posterolateral and midline herniation has been greatly facilitated. This communication reports the use of CT discography in the preoperative evaluation of two patients who were shown at discography and proven at operation to have extreme lateral disc herniations.

Acrylic stabilization of the cervical spine for neoplastic disease: evolution of a technique for vertebral body replacement.

The resection of collapsed cervical vertebral bodies affected by malignant lytic lesions often requires innovative methods for stabilization. Over the years, immediate stabilization of the cervical spine has been achieved with acrylic bridges, preformed metallic placement bodies, fibular strut grafts, and other aids. Because acrylic bonds poorly to adjacent bony structures, techniques to assure the adequate fixation of an acrylic bridge between resected vertebral bodies are needed.
