✓ The management of 10 patients with symptomatic localized intradural extramedullary spinal metastasis is reviewed. The single most common primary source was carcinoma of the breast (four cases). The initial symptom in nine patients was pain, with five patients reporting a characteristically severe cramping discomfort with radicular distribution. All patients underwent laminectomy decompression. At the time of surgery, six of the patients were weak but ambulatory and four were bedridden. Following surgery, four patients enjoyed some measure of pain relief, seven patients became ambulatory, and three remained bedridden. Two patients achieved a “satisfactory” result, and were walking and continent 6 months after surgery. Secondary brain tumors were demonstrated or implicated in nine patients, supporting the concept that the spinal metastases represented tertiary deposits following dissemination via the cerebrospinal fluid. Symptomatic intradural extramedullary spinal metastasis causes a virulent clinical syndrome with poor prognosis and disappointing outcome after treatment. Given the high incidence of associated cerebral metastatic involvement, total neuraxis radiation and/or chemotherapy should be considered when symptomatic spinal metastasis is discovered to be intradural and extramedullary.

Object. Single-dose radiosurgery for solitary spinal metastases can achieve rapid and durable pain control. This study was conducted to determine the patterns of failure after spinal radiosurgery. Methods. Forty-nine patients with 61 solitary spinal metastases underwent radiosurgery between May 2001 and May 2003. Single-dose radiosurgery (10–16 Gy) was delivered only to the involved spinal segments. The authors undertook a retrospective review of clinical notes, including patient questionnaires and radiological studies (computerized tomography or magnetic resonance imaging), to analyze patterns of failure following radiosurgery with regard to the pain and tumor control. Complete and partial pain relief was achieved in 85% of the lesions treated. Relapse of pain at the treated site was noted in 7%. Radiologically, lesions progressively metastasized to the immediately adjacent spines in 5%. These patients also had progressive primary and/or other systemic metastatic diseases. Conclusions. Spine-related pain control/reduction was excellent. Tumor recurrence at the treated segment and progression to the immediately adjacent region were rare. The results support the use of spinal radiosurgery as an effective treatment option for solitary spinal metastasis.

✓ Patients with symptomatic spinal metastases and limited life expectancy are often too debilitated to withstand anterior or posterolateral spinal cord decompression and segmental stabilization. More limited surgery aiming solely at preservation or restoration of neurological function and relief from pain offers the potential for significant improvement in the quality of remaining life without incurring undue perioperative morbidity and mortality. Eight patients with spinal metastases and limited life expectancy underwent a unilateral transpedicular decompression procedure on their most symptomatic side and/or the side of maximum tumor involvement. All patients were neurologically improved within the 1st postoperative week; all were ambulatory and continent postoperatively. Postoperatively, all five patients with preoperative motor deficits demonstrated increased motor strength, and the three patients with predominant radicular pain reported marked improvement. There were no perioperative deaths and two transient perioperative complications. The average length of hospitalization was 6 days for patients without complications and 10 days for the entire group. Unilateral transpedicular decompression without stabilization is an effective and safe method for palliating symptomatic spinal metastases in debilitated patients with widespread malignancy and limited life expectancy. This therapeutic option should be considered in select cases as an alternative to either nonoperative management or anterior or posterolateral decompression and segmental stabilization.

✓ A series of 80 cases of medulloblastomas in children undergoing operation and postoperatively followed between 1980 and 1990 at Great Ormond Street Hospital for Children (GOSH) has been reviewed and compared to an earlier series reported from the same institution by McIntosh. The overall 5-year survival rate for the present series was 50%, although three patients died after surviving 5 years. The operative mortality rate was 5%. Survival analysis revealed that the presence or absence of spinal metastases and the necessity for some form of cerebrospinal fluid diversion within 30 days of the operation independently significantly affected survival in this series. Those patients with no spinal metastasis and total tumor removal had a 5-year survival rate of 73%, making this the most favorable subgroup in the series. Patient age and gender, duration of symptoms, Chang T stages, tumor volume, extent of resection, and postoperative chemotherapy were not significant variables. Although these results are better than those reported in the earlier GOSH series, they are not significantly different from the results of the second 5-year cohort of patients described in that article. Radiotherapy remains the greatest advance in treatment, although it is hoped that further improvement will result from the various chemotherapy protocols now being studied and from increasing knowledge of the biological behavior of these tumors.

✓ A case is reported of a 45-year-old man who developed quadriplegia following a trivial motor-vehicle accident. Investigation including computerized tomography (CT) of the cervical spine revealed a large calcified lesion displacing the spinal cord and nerve roots, which proved to be a tuberculoma. The case is unusual in regard to the age of the patient, the size, location, and nature of the lesion, the mode of presentation, and the delineation of the lesion by CT scanning.

Metastatic Prostate Carcinoma

✓ Despite the relatively high incidence of prostate carcinoma involving the spinal column, those that are associated with spinal intradural extramedullary metastases are rare. The role of surgery for metastases to this spinal compartment is limited and palliative because presentation tends to be late in the course of the disease, particularly for prostate carcinoma. It is also considered to be part of the spectrum of leptomeningeal carcinomatosis and is associated with a high incidence of brain metastases. The authors review a rare case of prostate carcinoma metastatic to the spinal intradural extramedullary space and discuss its clinical presentation, imaging features, and surgical management.

✓ The incidence of chronic tonsillar herniation (CTH) was evaluated with magnetic resonance imaging in 44 patients with Crouzon's syndrome and 51 with Apert's syndrome; the incidence was 72.7% in Crouzon's syndrome and 1.9% in Apert's syndrome. All the patients with Crouzon's syndrome and progressive hydrocephalus had CTH, but of 32 individuals with Crouzon's syndrome and CTH, only 15 had progressive hydrocephalus. Five patients with Apert's syndrome were treated for progressive hydrocephalus; none had CTH. The patterns of suture closure in these two groups of patients were studied, and significant differences in coronal, sagittal, and lambdoid sutures were found between patients with Crouzon's and Apert's syndromes. In Crouzon's syndrome, significant differences in the pattern of lambdoid suture closure were found between the groups with and without CTH; in the group with CTH, the lambdoid closure appeared earlier. The authors propose that the high incidence of individuals with CTH who have Crouzon's syndrome is related to the premature synostosis of the lambdoid suture in the first 24 months of age.

Object. Some authors have questioned the need to perform cerebral angiography in patients presenting with a benign clinical picture and a perimesencephalic pattern of subarachnoid hemorrhage (SAH) on initial computerized tomography (CT) scans, because the low probability of finding an aneurysm does not justify exposing patients to the risks of angiography. It has been stated, however, that ruptured posterior circulation aneurysms may present with a perimesencephalic SAH pattern in up to 10% of cases. The aim of the present study was twofold: to define the frequency of the perimesencephalic SAH pattern in the setting of ruptured posterior fossa aneurysms, and to determine whether this clinical syndrome and pattern of bleeding could be reliably and definitely distinguished from that of aneurysmal SAH. Methods. Twenty-eight patients with ruptured posterior circulation aneurysms and 44 with nonaneurysmal perimesencephalic SAH were selected from a series of 408 consecutive patients with spontaneous SAH admitted to the authors' institution. The admission unenhanced CT scans were evaluated by a neuroradiologist in a blinded fashion and classified as revealing a perimesencephalic SAH or a nonperimesencephalic pattern of bleeding. Of the 28 patients with posterior circulation aneurysms, five whose grade was I according to the World Federation of Neurosurgical Societies scale were classified as having a perimesencephalic SAH pattern on the initial CT scan. The data show that the likelihood of finding an aneurysm on angiographic studies obtained in a patient with a perimesencephalic SAH pattern is 8.9%. Conversely, ruptured aneurysms of the posterior circulation present with an early perimesencephalic SAH pattern in 16.6% of cases. Conclusions. This study supports the impression that there is no completely sensitive and specific CT pattern for a nonaneurysmal SAH. In addition, the authors believe that there is no specific clinical syndrome that can differentiate patients who have a perimesencephalic SAH pattern caused by an aneurysm from those without aneurysms. Digital subtraction angiography continues to be the gold standard for the diagnosis of cerebral aneurysms and should be performed even in patients who have the characteristic perimesencephalic SAH pattern on admission CT scans.

✓ The clinical course of 50 patients with conservatively treated intracranial arteriovenous malformations (AVM's) was followed, most of them for more than 5 years. The average follow-up period was 13.4 years. The initial symptom was intracranial bleeding in 29 patients (58%) and seizure in 15 patients (30%). Small and deep-seated AVM's were associated with a high incidence of bleeding; however, repeated hemorrhages were not necessarily indicative of a poor prognosis. Children younger than 15 years had a better prognosis than adults. There was no correlation between pregnancy and bleeding. In the hemorrhage group, the incidence of rebleeding was 6.9% in the 1st year after initial rupture, 1.91% per year after 5 years, and 0.92% per year after 15 years. The overall incidence of rebleeding was 34.5% in the hemorrhage group. Of the 50 patients, 37 (74%) had a good clinical outcome, four (8%) had a fair outcome, and four (8%) had a poor outcome; five patients died.
