✓ Computerized tomography (CT) has made it easier to distinguish tumoral from nontumoral diseases of the central nervous system. In the presence of mass effect, however, this distinction may be difficult or impossible to make. Primary demyelinating disease may occasionally present as a focal cerebral mass. The authors report three cases of primary demyelinating disease of the brain involving the corpus callosum and periventricular white matter and associated with mass effect, which proved difficult to differentiate from infiltrating “butterfly” gliomas.

Object. Capillary hemangiomas are benign tumors or tumorlike lesions that originate from blood vessels and have rarely been reported to develop in the brain or spinal cord. The authors summarize the clinical and histological features of capillary hemangiomas of the central nervous system (CNS). Methods. The clinical features, imaging characteristics, and outcomes in 10 patients with CNS capillary hemangiomas were reviewed. Histological studies included immunostaining with CD31, α-smooth muscle actin, vascular endothelial growth factor, and Ki-67 antigen. Three patients with lesions in the brain presented with symptoms of increased intracranial pressure or seizures. Seven patients with lesions in the spinal cord presented with progressive sensorimotor disturbances of the lower limbs. Computerized tomography and magnetic resonance imaging demonstrated well-defined, enhancing lesions associated with marked perifocal edema. Angiography demonstrated hypervascular lesions, which have not recurred after resection. In two cases, multiple satellite lesions resolved after the systemic administration of steroid drugs or interferon-α. Histologically, all lesions were consistent with findings of capillary hemangioma of the skin or soft tissues. The CNS lesions differed significantly from other vascular neoplasms, such as hemangioendotheliomas, hemangiopericytomas, and hemangioblastomas. Conclusions. Capillary hemangiomas of the CNS are benign lesions that can be surgically removed and cured without adjuvant therapy.

Object. Achieving distribution of gene-carrying vectors is a major barrier to the clinical application of gene therapy. Because of the blood—brain barrier, the distribution of genetic vectors to the central nervous system (CNS) is even more challenging than delivery to other tissues. Direct intraparenchymal microinfusion, a minimally invasive technique, uses bulk flow (convection) to distribute suspensions of macromolecules widely through the extracellular space (convection-enhanced delivery [CED]). Although acute injection into solid tissue is often used for delivery of oligonucleotides, viruses, and liposomes, and there is preliminary evidence that certain of these large particles can spread through the interstitial space of the brain by the use of convection, the use of CED for distribution of viruses in the brain has not been systematically examined. That is the goal of this study. Methods. Investigators used a rodent model to examine the influence of size, osmolarity of buffering solutions, and surface coating on the volumetric distribution of virus-sized nanoparticles and viruses (adeno-associated viruses and adenoviruses) in the gray matter of the brain. The results demonstrate that channels in the extracellular space of gray matter in the brain are large enough to accommodate virus-sized particles and that the surface characteristics are critical determinants for distribution of viruses in the brain by convection. Conclusions. These results indicate that convective distribution can be used to distribute therapeutic viral vectors in the CNS.

✓ The term “nasal glioma” is a confusing misnomer as it implies a neoplastic condition with malignant potential, which it is not. Nasal glioma is a rare developmental abnormality and should be differentiated from glioma, which is a malignant tumor of the brain, and from a primary encephalocele, which is herniation of the cranial contents through a bone defect in the skull, through which it retains an intact connection with the central nervous system. Two cases of nasal glioma, one with and one without intracranial connections, are described and the literature is reviewed.

✓ The tapeworm Spirometra mansonoides infects man worldwide, particularly in Asian countries. Rarely, the central nervous system is involved; such a case is presented here. In the total of 12 reported cases, including the case described, the worm presented clinically as a mass suspicious for neoplasm or chronic abscess cavity. Surgical removal was invariably curative in each case. Although infrequent, the possibility of tapeworm infection should be entertained in the evaluation of intracranial masses in patients who have visited exotic locales.

✓ Local recurrence developed 6 years after the initial resection of an intraspinal meningeal tumor that originally was thought to be an angioblastic meningioma. Histological review of the pathology led to a change of that diagnosis to one of mesenchymal chondrosarcoma. The recurrent vascular tumor was embolized, then totally excised. Because this tumor had malignant features, the patient received irradiation and chemotherapy. No evidence of regrowth has been observed during a period of more than 4 years. Mesenchymal chondrosarcomas of the central nervous system and their treatment are reviewed.

✓ Two patients are reported who had intracerebral mass lesions composed of hemangioma and glial neoplasm. After excision, one recurred as an oligodendroglioma, and the remnant of the other remained static over a 5-year period. These lesions may represent a subgroup of cerebral hemangiomas that have the biological potential for future glial neoplastic growth. Reference is made to experimental work with polyoma virus which can induce cavernous hemangiomas in the central nervous system in mice, and which is a papovavirus. Other papovaviruses can induce ependymomas in hamsters.

✓ Superficial siderosis is a rare condition characterized by deposition of hemosiderin in the leptomeninges and in the subpial layers of the brain and spinal cord. It is associated with cerebrospinal fluid abnormalities consistent with recurrent bleeding into the subarachnoid space. The usual symptoms are hearing loss, ataxia, spastic paraparesis, sensory and sphincter deficits, and mental deterioration. A case is presented of severe superficial siderosis of the central nervous system in a 51-year-old man who had suffered a brachial plexus injury at the age of 20 years. The diagnosis was made by means of magnetic resonance imaging 16 years after the initial symptoms, which comprised bilateral hearing loss and anosmia. Subarachnoid bleeding was due to traumatic pseudomeningocele of the brachial plexus, a very unusual cause of superficial siderosis. This case is interesting insofar as the surgical treatment prevented further bleeding and possibly progression of the disease.
