✓ The concept of hemorrhage in a preexisting syringomyelic cavity was first described by Gowers in 1904. Since its first description only 13 cases have been reported. The aims of this report are to describe a new case, bring this entity to wider attention, and summarize the existing literature on the subject. This 36-year-old woman presented with progressive gait disturbance and unsteadiness. Physical examination revealed incomplete quadriparesis, predominantly on the left side, and hypesthesia below C-7. Magnetic resonance imaging revealed hematomyelia characterized by a heterogeneous hyperintense signal within the central cervical cord. A liquefied well-limited hematoma was evacuated. The postoperative course was uneventful; a near-complete recovery was observed at the 7-year follow-up examination. Most cases of intrasyringal hemorrhage (ISH) have occurred in syringomyelic cavities associated with scoliosis or Chiari malformation Type I. Although there is no specific clinical picture associated with this entity, it can be characterized by three neurological forms: 1) sudden onset or rapid development of signs and symptoms, 2) acute worsening of symptoms that may improve but leaving greater neurological dysfunction than before the previous episode, and 3) ISH may initiate progressive deterioration in a patient with known syringomyelia. Intrasyringal bleeding is most probably caused by a sudden dilation of the syringomyelic cavity, which may provoke rupture of the intrasyringal vessels by an acute distension of the accompanying strands. Magnetic resonance imaging is the most accurate diagnostic modality, and recognition of ISH can lead to early, safe, and efficient surgical treatment.

✓ The authors report gigantism in a 16-month-old boy with an extensive optic pathway glioma infiltrating into somatostatinergic pathways, as revealed by magnetic resonance imaging and immunocytochemical studies. Stereotactic biopsies of areas showing hyperintense signal abnormalities on T2-weighted images in and adjacent to the involved visual pathways provided rarely obtained histological correlation of such areas. The patient received chemotherapy, which resulted in reduction of size and signal intensity of the tumor and stabilization of vision and growth velocity.

✓ Magnetic resonance imaging (MRI) was performed on 12 patients with spinal arteriovenous malformations (AVM's). Six lesions were intramedullary, five were dural, and one was in a posterior extramedullary location. Serpentine filling defects similar to the classic myelographic findings were demonstrated within the high-signal cerebrospinal fluid on T2-weighted coronal scans. The intramedullary nidus was identified by MRI as an area of low-signal intensity within the cord in all six intramedullary AVM's. Neither the dural nor the posterior extramedullary lesions showed intramedullary components. It is concluded that MRI may noninvasively provide the initial diagnosis of a spinal AVM and distinguish intramedullary from dural and extramedullary lesions.

✓ The lower brainstem and cervical spinal cord from an ordinarily treated case of Chiari Type I hindbrain hernia associated with syringomyelia was examined using high-resolution magnetic resonance microscopy and standard neuropathological techniques. Magnetic resonance microscopy allows total screening and visualizes the disturbed internal and external microanatomy in the three orthogonal planes with the resolution of low-power optical microscopy. An additional advantage is the in situ visualization of the shunts. Afterwards the intact specimen is still available for microscopic examination. Part of the deformation of the medulla is caused by chronic tonsillar compression and molding inside the foramen magnum. Other anomalies, such as atrophy caused by demyelination, elongation, and unusual disturbances at the level of the trigeminal and solitary nuclear complexes contribute to the deformation. At the level of the syrinx-free upper part of the cervical cord, anomalies of the dorsal root and the dorsal horn are demonstrated.

✓ Gangliogliomas of the optic nerve are extremely rare. The case is reported of a 38-year-old man who presented with a visual field deficit and was discovered to have an optic nerve ganglioglioma. The possible embryological origins of this neoplasm, its histological and immunohistochemical features, and its appearance on magnetic resonance imaging are examined. The prognoses of optic nerve glioma and of gangliogliomas occurring elsewhere in the nervous system are compared.

Object. The authors examined the relationships of brain—tumor interfaces, specific magnetic resonance (MR) imaging features, and angiographic findings in meningiomas to predict tumor cleavage and difficulty of resection.Methods. Magnetic resonance imaging studies, angiographic data, operative reports, clinical data, and histopathological findings were examined retrospectively in this series, which included 126 patients with intracranial meningiomas who underwent operations in which microsurgical techniques were used. The authors have identified three kinds of brain—tumor interfaces characterized by various difficulties in microsurgical dissection: smooth type, intermediate type, and invasive type. The signal intensity on T1-weighted MR images was very similar regardless of the type of brain—tumor interface (p > 0.1). However, on T2-weighted images the different interfaces seemed to correlate very precisely with the signal intensity and the amount of peritumoral edema (p < 0.01), allowing the prediction of microsurgical effort required during surgery. On angiographic studies, the pial—cortical arterial supply was seen to participate almost equally with the meningeal—dural arterial supply in vascularizing the tumor in 57.9% of patients. Meningiomas demonstrating hypervascularization on angiography, particularly those fed by the pial—cortical arteries, exhibited significantly more severe edema compared with those supplied only from meningeal arteries (p < 0.01). Indeed, a positive correlation was found between the vascular supply from pial—cortical arteries and the type of cleavage (p < 0.05).Conclusions. In this analysis the authors proved that there is a strong correlation between the amount of peritumoral edema, hyperintensity of the tumor on T2-weighted images, cortical penetration, vascular supply from pial—cortical arteries, and cleavage of the meningioma. Therefore, the consequent difficulty of microsurgical dissection can be predicted preoperatively by analyzing MR imaging and angiographic studies.

✓ The authors describe a unique presentation of Wegener granulomatosis (WG) manifesting predominantly as meningitis. Magnetic resonance imaging demonstrated diffuse meningeal enhancement, including the pia mater, in a 28-yearold man with meningitis. A diagnosis of atypical WG was based on the findings of a dural biopsy sample and an elevated cytoplasmic antineutrophil cytoplasmic antibody (cANCA) titer, although the patient did not have any of the lesions common to WG. Immunosuppressive therapy was quite effective. With treatment, the meningeal enhancement resolved and the cANCA titer normalized. Meningeal granulomatosis as the sole lesion in WG has never been reported in the literature. This atypical course of WG should be noted.
