Neuroradiological Imaging

✓ The unusual presentation of acute megakaryoblastic leukemia as a temporal bone granulocytic sarcoma in an infant without systemic manifestations of leukemia is reviewed. Leukemia should be considered in the differential diagnosis of skull and skull-based lesions since the appearance on neuroradiological imaging is not unique in this diagnosis. Surgical treatment, as in this case, is limited to obtaining tissue for diagnosis and draining the infection.

✓ The authors describe the clinical, pathological, and therapeutic aspects of a case of focal temporal lobe eosinophilic granuloma, presenting with otitis media and meningitis, and evolving subsequently into a temporal lobe mass. This triad, otitis media, meningitis, focal cerebral lesion with systemic manifestations of inflammation, eosinophilia of blood and cerebrospinal fluid, should suggest eosinophilic granuloma in the differential diagnosis. The lesion is sensitive to relatively small doses of radiation.

✓ This report reviews the characteristic symptoms of disabling positional vertigo (DPV), and the tests used to reach a differential diagnosis of this disorder. Twenty-one patients were operated on consecutively for management of DPV between March, 1983, and September, 1984. In all patients one or more arteries or veins was found to be compressing the eighth cranial nerve when the nerve was exposed for microvascular decompression to relieve the symptoms of DPV. After the operation, 16 of the 21 patients were free of symptoms, or symptoms were so much improved that the patients returned to normal work or social life. Two patients had no improvement and three had limited relief of symptoms postoperatively. None of the patients experienced hearing loss as a result of the operation to relieve DPV, but one patient suffered a cerebellar contusion during the operation.

✓ Results in 27 cases of intracranial surgery for metastatic lung cancer are evaluated with regard to both the quality and duration of survival; 56% of the patients lived more than 1 year, with the longest survivor still living 32 months after operation. The operative mortality was 26%. These data suggest that intracranial surgery is worthwhile in patients with lung cancer when the cerebral metastasis is either solitary or single.

✓ Hemangiopericytoma is a vascular neoplasm consisting of capillaries outlined by an intact basement membrane that separates the endothelial cells of the capillaries from the spindle-shaped tumor cells in the extravascular area. These neoplasms are found in soft tissues but have rarely been shown to involve the spinal canal. This is a report of three such cases. Surgical removal of the tumor from the spinal canal was technically difficult. A high risk of recurrence has been reported but in these three cases adjunctive radiotherapy appeared to be of benefit in controlling the progression of the disease. These cases, added to the six cases in the literature, confirm the existence of hemangiopericytoma involving the vertebral column with extension into the spinal canal. This entity should be included in the differential diagnosis of lesions of the spinal canal. The risk of intraoperative hemorrhage should be anticipated.

Deep Brain

Object. The surgical treatment of Parkinson disease (PD) has undergone a dramatic shift, from stereotactic ablative procedures toward deep brain stimulaion (DBS). The authors studied this process by investigating practice patterns, mortality and morbidity rates, and hospital charges as reflected in the records of a representative sample of US hospitals between 1996 and 2000. Methods. The authors conducted a retrospective cohort study by using the Nationwide Inpatient Sample database; 1761 operations at 71 hospitals were studied. Projected to the US population, there were 1650 inpatient procedures performed for PD per year (pallidotomies, thalamotomies, and DBS), with no significant change in the annual number of procedures during the study period. The in-hospital mortality rate was 0.2%, discharge other than to home was 8.1%, and the rate of neurological complications was 1.8%, with no significant differences between procedures. In multivariate analyses, hospitals with larger annual caseloads had lower mortality rates (p = 0.002) and better outcomes at hospital discharge (p = 0.007). Placement of deep brain stimulators comprised 0% of operations in 1996 and 88% in 2000. Factors predicting placement of these devices in analyses adjusted for year of surgery included younger age, Caucasian race, private insurance, residence in higher-income areas, hospital teaching status, and smaller annual hospital caseload. In multivariate analysis, total hospital charges were 2.2 times higher for DBS (median $36,000 compared with $12,000, p < 0.001), whereas charges were lower at higher-volume hospitals (p < 0.001). Conclusions. Surgical treatment of PD in the US changed significantly between 1996 and 2000. Larger-volume hospitals had superior short-term outcomes and lower charges. Future studies should address long-term functional end points, cost/benefit comparisons, and inequities in access to care.

Object. The authors conducted a study to compare the efficacies of three nonsurgical treatment strategies in patients with sciatica. Their hypothesis was that bed rest, physiotherapy, and continuation of activities of daily living (ADLs) (control treatment) are each of equivalent efficacy. Methods. This randomized controlled trial was designed for comparison of bed rest, physiotherapy, and continuation of ADLs. The setting was an outpatient clinic. General practitioners were asked to refer patients for treatment as soon as possible. The authors enrolled 250 patients (< 60 years of age) with sciatica of less than 1-month's duration and who had not yet been treated with bed rest or physiotherapy. Primary outcome measures were radicular pain (based on a visual analog pain scale [VAPS]) and hampered ADLs (Quebec Disability Scale [QDS]). Secondary outcome measures were the rates of treatment-related failure and surgical treatment. Measures were assessed at baseline and during follow up at 1, 2, and 6 months. Mean differences in VAPS and QDS scores between bed rest and control treatment were 2.5 (95% confidence interval [CI] −6.4 to 11.4) and −4.8 (95% CI −10.6 to 0.9) at 1 month and 0.9 (95% CI −8.7 to 10.4) and −2.7 (95% CI −9.9 to 4.4) at 2 months, respectively. The respective differences between physiotherapy and control treatment were 0.8 (95% CI −8.2 to 9.8) and −0.5 (95% CI −6.3 to 5.3) at 1 month and −0.3 (95% CI −9.4 to 10) and 0.0 (95% CI −7.2 to 7.3) at 2 months. The respective odds ratios for treatment failure and surgical treatment of bed rest compared with control treatment were 1.6 (95% CI 0.8–3.5) and 1.5 (95% CI 0.7–3.6) at 6 months. When physiotherapy was compared with control treatment, these ratios were 1.5 (95% CI 0.7–3.2) and 1.2 (95% CI 0.5–2.9) at 6 months, respectively. Conclusions. Bed rest and physiotherapy are not more effective in acute sciatica than continuation of ADLs.

✓ Meningiomas arising from the falcotentorial junction are extremely rare. The authors describe the clinical features, neuroimaging studies, and results of surgical treatment of meningiomas of the falcotentorial junction and clarify the characteristics of this lesion based on a review of the literature and seven patients treated at their institution. The most common symptoms resulted from intracranial hypertension. Upward-gaze palsy appeared in only one patient. Computerized tomography (CT) showed no specific findings, but there was no evidence of edema around the tumor. Magnetic resonance (MR) imaging revealed a round, smooth-bordered mass with a peritumoral rim, without edema, and showing marked contrast enhancement. The multiplanar capability of MR imaging delineated the relationship between the tumor and adjacent structures better than did CT. Detailed knowledge of the vascular structures, especially evidence of occlusion of the galenic venous system and the development of collateral venous channels, is critical for successful surgery; stereoscopic cerebral angiography is necessary to achieve this aim. The seven patients described developed five types of collateral venous channels: through the basal vein of Rosenthal to the petrosal vein, through the veins on the medial surface of the parietal and occipital lobes to the superior sagittal sinus, through superficial anastomotic veins, through veins of the posterior fossa to the transverse or straight sinus, and through the falcian veins to the superior sagittal sinus. The first three types mainly developed after occlusion of the galenic system. The tumors were removed through the occipital transtentorial approach with a large window at the posterior part of the falx. A favorable prognosis for patients undergoing surgical treatment of falcotentorial junction meningiomas can be expected if detailed neuroimaging studies and microsurgical techniques are used.
