✓ A 26-year-old man presented with expressive aphasia, weakness of the right arm, and anemia but there was no family history of hereditary hemorrhagic telangiectasia. Computerized tomography (CT) of the head demonstrated an enhancing left frontal mass, which was aspirated and on culture yielded multiple organisms. Pulmonary arteriovenous fistulae identified in both lungs by chest radiography, CT, and angiography were treated with coil embolization. Treatment of pulmonary arteriovenous fistulae and prolonged surveillance are necessary to prevent future neurological complications.

✓ This is an analysis of 10 cases of dermoid tumor occurring in the spinal canal (8 lumbar and 2 thoracic). Low-back pain was the commonest presenting symptom, especially if the tumor was adherent to the conus medullaris. Other complaints included urinary dysfunction and motor and sensory disturbances of the legs. Clinical and radiological evidence of spina bifida was found in about half of the cases and suggested the diagnosis of a developmental type of tumor when patients presented with progressive spinal cord compression. At operation, the tumors were often found embedded in the conus medullaris or firmly adherent to the cauda equina, thus precluding complete removal. Evacuation of the cystic contents, however, gave lasting relief of the low-back pain and did not cause any deterioration in neurological function. In a follow-up study, ranging from 1 to 15 years, virtually no improvement in the neurological signs was observed. On the other hand, only one case has deteriorated due to recurrence of tumor growth.

✓ A case of a neurocytoma involving a nerve root of the cauda equina in a 46-year-old woman is reported. The patient presented with a 2-month history of progressive left lower-extremity weakness and pain and decreased ability to walk, as well as complaints of incomplete voiding. A magnetic resonance image revealed a 7-mm oval mass that was located intrathecally and extended from T-12 to L-1 and was adjacent to a nerve root. No lesions were identified at higher vertebral levels. The mass was excised. On histological examination it was found to have classical features of a neurocytoma. To the best of the authors' knowledge, this is the first report of a neurocytoma occurring in that region. A detailed histological description of this case and review of the pertinent literature are provided.

Object. The goals of this study were to define the natural history and growth pattern of hemangioblastomas of the central nervous system (CNS) that are associated with von Hippel—Lindau (VHL) disease and to correlate features of hemangioblastomas that are associated with the development of symptoms and the need for treatment. Methods. The authors reviewed serial magnetic resonance images and clinical histories of 160 consecutive patients with VHL disease who harbored CNS hemangioblastomas and serially measured the volumes of tumors and associated cysts. Six hundred fifty-five hemangioblastomas were identified in the cerebellum (250 tumors), brainstem (64 tumors, all of which were located in the posterior medulla oblongata), spinal cord (331 tumors, 96% of which were located in the posterior half of spinal cord), and the supratentorial brain (10 tumors). The symptoms were related to a mass effect. A serial increase in hemangioblastoma size was observed in cerebellar, brainstem, and spinal cord tumors as patients progressed from being asymptomatic to symptomatic and requiring surgery (p < 0.0001). Twenty-one (72%) of 29 symptom-producing cerebellar tumors had an associated cyst, whereas only 28 (13%) of 221 nonsymptomatic cerebellar tumors had tumor-associated cysts (p < 0.0001). Nine (75%) of 12 symptomatic brainstem tumors had associated cysts, compared with only four (8%) of 52 nonsymptomatic brainstem lesions (p < 0.0001). By the time the symptoms appeared and surgery was required, the cyst was larger than the causative tumor; cerebellar and brainstem cysts measured 34 and 19 times the size of their associated tumors at surgery, respectively. Ninety-five percent of symptom-producing spinal hemangioblastomas were associated with syringomyelia. The clinical circumstance was dynamic. Among the 88 patients who had undergone serial imaging for 6 months or longer (median 32 months), 164 (44%) of 373 hemangioblastomas and 37 (67%) of 55 tumor-associated cysts enlarged. No tumors or cysts spontaneously diminished in size. Symptomatic cerebellar and brainstem tumors grew at rates six and nine times greater, respectively, than asymptomatic tumors in the same regions. Cysts enlarged seven (cerebellum) and 15 (brainstem) times faster than the hemangioblastomas causing them. Hemangioblastomas frequently demonstrated a pattern of growth in which they would enlarge for a period of time (growth phase) and then stabilize in a period of arrested growth (quiescent phase). Of 69 patients with documented tumor growth, 18 (26%) harbored tumors with at least two growth phases. Of 160 patients with hemangioblastomas, 34 patients (median follow up 51 months) were found to have 115 new hemangioblastomas and 15 patients new tumor-associated cysts. Conclusions. In this study the authors define the natural history of CNS hemangioblastomas associated with VHL disease. Not only were cysts commonly associated with cerebellar, brainstem, and spinal hemangioblastomas, the pace of enlargement was much faster for cysts than for hemangioblastomas. By the time symptoms appeared, the majority of mass effect—producing symptoms derived from the cyst, rather than from the tumor causing the cyst. These tumors often have multiple periods of tumor growth separated by periods of arrested growth, and many untreated tumors may remain the same size for several years. These characteristics must be considered when determining the optimal timing of screening for individual patients and for evaluating the timing and results of treatment.

✓ A case of multiple hemangiomas of the cauda equina nerve roots, conus medullaris, and lower spinal cord is described. The 74-year-old male patient presented with a 9-month history of progressive bilateral leg weakness. He had a history of lymphoma at the age of 39 years and renal cell carcinoma in his early 40s. Neither disease was evident at the time of this presentation. A magnetic resonance image revealed multiple enhancing nodules in the cauda equina region as well as on the pial surface of the lower thoracic spinal cord and conus medullaris. The patient underwent an L2–3 laminectomy. Cauda equina nerve roots were found to be studded with numerous purple nodules, the largest measuring 6 to 8 mm. The nodules were adherent to nerve roots from which they could not be resected. Two lesions were histologically examined and found to be capillary hemangiomas. Twelve months into an uneventful postoperative course, the patient is neurologically unchanged. This unique case might represent a distinct form of hemangiomatosis confined to the cauda equina nerve roots and spinal cord.

✓ When an intraspinal expanding lesion causes a spinal block, a segment of the spinal cord or cauda equina will be subjected to general pressure from the surrounding tissue. This spinal block pressure, the spinal equivalent to intracranial pressure, was measured by lumbar infusion of fluid and simultaneous recording of the volume-pressure curve caudal to the block. The point of deviation from or breakthrough of the exponential volume-pressure curve indicated the spinal block pressure. Spinal block pressure of about 500 mm H2O and more could be determined by this method, and, when it was combined with Queckenstedt's test, lower pressures could be assessed as well. In the static (thoracic) part of the spine, spinal block pressure up to the level of arterial blood pressure was recorded. In the dynamic part of the spine, however, spinal block pressure could exceed arterial blood pressure due to external compressive forces during extension of the spine. There was a general tendency for more severe neurological deficits in patients with high spinal block pressure; but the duration of the pressure, additional focal pressure, and spinal cord compared with nerve root compression seemed equally important factors. The recording has implications for diagnosis, positioning of patients for myelography and surgery, selection of high-risk patients for the most appropriate surgical procedure, and detection of postoperative hematoma. There were no complications associated with the recordings.

✓ Stereotactic and functional neurosurgery has experienced a remarkable degree of development during the last 50 years, from the plaster of Paris frame of Spiegel and Wycis to the technology of frameless stereotaxis. Although predominantly used for intracranial procedures, stereotaxy has its roots in experimental studies of the spinal cord. The field of spinal cord stereotaxy has not received the same amount of attention as supratentorial surgery, but there have been significant contributions to the field that have helped to further our understanding of spinal cord anatomy and physiology. Now that frameless stereotaxis has reached clinical practice, there may be further developments in the field of spinal surgery: this technique may prove useful for spinal fusion operations and, possibly, intramedullary operations as well.
