✓ The authors report an unusual case of an extensive spontaneous subgaleal hematoma caused by a bilateral arteriovenous shunting lesion involving the diploic veins. The enlarged diploic canals and the existence of bilateral diploic arteriovenous shunts with no history of fracture or trauma indicate that these fistulas developed spontaneously over a long period of time. Angiographic findings in these unusual arteriovenous shunting lesions and their endovascular management are briefly illustrated. A case of a bilateral diploic fistula has not been reported before and it may contribute to the understanding of the diversity of dural arteriovenous shunting lesions.

✓ The authors present an unusual case in which increased intracranial pressure developed because of multiple-suture craniosynostosis and megaloencephaly in a child with a previously undiagnosed lysosomal storage disease, α-d-mannosidase deficiency. This 3-year-old boy presented with a history of frequent naps, headaches, florid papilledema, enlarged head (> 95th percentile), elevated opening pressure by lumbar puncture, a “beaten copper” appearance on skull radiographs, and no hydrocephalus. Multiple synostectomies were performed. Postoperatively, the child's headaches and papilledema resolved and his level of physical activity increased dramatically. The authors discuss the paradoxical presentation of prematurely fused sutures and macrocrania in light of this lysosomal storage disease and its subsequent management.

✓ The authors report the case of a 55-year-old woman who developed a symptomatic craniopharyngioma within 2 years of obtaining a normal magnetic resonance image of her brain. Craniopharyngiomas are histologically benign tumors. They are thought to arise from embryonic remnants of Rathke's pouch and sac and to manifest themselves clinically after a steady growth that commences in fetal life. To the authors' knowlege, this is the first report that documents a tumor arising de novo in the sixth decade of life. This report appears to challenge the concept of the origin and natural history of craniopharyngiomas.

Object. The purpose of this study was to identify factors predictive of postoperative oculomotor nerve palsy among patients who undergo surgery for distal basilar artery (BA) aneurysms. The data can be used to estimate preoperative risk in this population. The natural history of oculomotor nerve palsy in patients with good outcomes is also defined. Methods. The cases of 163 patients with distal BA aneurysms, who were treated surgically between 1996 and 2002, were retrospectively studied to identify factors contributing to oculomotor nerve palsy. After the data had been collected, stepwise logistic regression procedures were used to determine the predictive effects of each variable on the development of oculomotor nerve palsy and to create a scoring system. Factors that interfered with resolution of oculomotor dysfunction in patients with good outcomes were also studied. Postoperative oculomotor nerve palsy occurred in 86 patients (52.8%) with distal BA aneurysms. The following factors were associated with postoperative oculomotor dysfunction, as determined by a categorical data analysis: 1) younger patient age (p < 0.001); 2) poor admission Hunt and Hess grade (p < 0.001); 3) use of temporary arterial occlusion (p < 0.001); 4) poor Glasgow Outcome Scale score (p < 0.001); and 5) the presence of a BA apex aneurysm that projected posteriorly (p < 0.001). For patients with good outcomes, postoperative oculomotor nerve palsy resolved completely within 3 months in 31 patients (52%) and within 6 months in 47 patients (80%). The projection of the BA aneurysm was associated with incomplete oculomotor recovery at 6 months postoperatively (p = 0.019). Conclusions. The results of this study can help identify patients with a high risk for the development of oculomotor nerve palsy. This may help neurosurgeons in preoperative planning and discussions.

✓ Fractures of the craniocervical junction are common in victims of high-speed motor vehicle accidents; indeed, injury to this area is often fatal. The authors present the unusual case of a young woman who sustained a circumferential fracture of the craniocervical junction. Despite significant trauma to this area, she suffered remarkably minor neurological impairment and made an excellent recovery. Her injuries, treatment, and outcome, as well as a review of the literature with regard to injuries at the craniocervical junction, are discussed.

✓ Cerebral venous angiomas are congenital anomalies of the intracranial venous drainage. Many believe that they are associated with a high risk of hemorrhage and neurological dysfunction, but newer neurodiagnostic imaging techniques are showing not only that they are more common than previously known but also that many have no associated symptoms. In this retrospective study, the natural history of venous angiomas was examined in 100 patients (48 males and 52 females) with radiographically identifiable lesions treated over a 14-year period. Information on the natural history of the lesion was obtained from clinical records and follow-up data. Imaging studies included angiography, computerized tomography, and magnetic resonance imaging. Angioma locations were classified as frontal (42 cases), parietal (24 cases), occipital (4 cases), temporal (2 cases), basal or ventricular (11 cases), cerebellar (14 cases), or brain stem (3 cases); 47 lesions were on the left side. Headache as a presenting symptom was common (36 patients) and often led to other radiographic studies, but this appeared to be related to the vascular lesion in only four patients. Other possibly related complications were hemorrhage in one patient, seizures in five, and transient focal deficits in eight. Fifteen patients had no neurological signs or symptoms. The mean patient age at last contact was 45.3 years (range 3 to 94 years). All patients have been managed without surgery. It is concluded that significant complications secondary to venous angiomas are infrequent and that surgical resection of these lesions and of surrounding brain is rarely indicated.

Object.The authors undertook a study to identify magnetic resonance (MR) imaging techniques that can be used reliably during gamma knife surgery (GKS) to identify the trigeminal nerve, surrounding vasculature, and areas of compression.Methods.Preoperative visualization of the trigeminal nerve and surrounding vasculature as well as targeting the area of vascular compression may increase the effectiveness of GKS for trigeminal neuralgia. During the past years our gamma knife centers have researched different MR imaging sequences with regard to their ability to visualize cranial nerves and vascular structures. Constructive interference in steady-state (CISS) fusion imaging with three-dimensional gradient echo sequences (3D-Flash) was found to be of greatest value in the authors' 25 most recent patients.In 24 (96%) out of the 25 patients, the fifth cranial nerve, surrounding vessels, and areas of compression could be reliably identified using CISS/3D-Flash. The MR images were acceptable despite patients' history of microvascular decompression, radiofrequency (RF) ablation, or concomitant disease. In one of 25 patients with a history of multiple RF lesions, the visualization was inadequate due to severe trigeminal nerve atrophy.Conclusions.The CISS/3D-Flash fusion imaging has become the preferred imaging method at the authors' institutions during GKS for trigeminal neuralgia. It affords the best visualization of the trigeminal nerve, surrounding vasculature, and the precise location of vascular compression.

✓ In a patient with glioblastoma treated with interferon (IFN-α) for a long period of time, a high titer of IFN-neutralizing antibody was detected in the serum during and after IFN therapy. Computerized tomography findings and neurological symptoms in this patient were unchanged during IFN therapy. General malaise, fever, anorexia, nausea, and decrease of leukocytes, platelets, erythrocytes, hemoglobin, and hematocrit were recognized transiently as side effects of IFN administration. These side effects were not serious and resolved spontaneously without discontinuation of therapy. The appearance of IFN-neutralizing antibody is clinically important because the antibody probably neutralizes the effect of systemically administered IFN before it reaches the site of action.

✓ Delayed complications associated with sublaminar and interspinous wiring in the pediatric cervical spine are rare. The authors present a case of delayed complication in which a cervical fusion wire migrated into the cerebellum, causing subsequent cerebellar abscess 2 years after posterior cervical arthrodesis. A craniotomy was required to remove the wire and drain the abscess. Despite their history of safety and successful fusion, procedures involving sublaminar and interspinous wiring carry a risk of neurological injury secondary to wire migration. A thorough neuroimaging evaluation is required in patients who have undergone fusion and who have neurological complaints to detect late instrumentation-related sequelae.
