The Central Nervous System

This chapter covers cancer of the central nervous system (CNS), including epidemiology and aetiology, classification, pathology and molecular genetics, clinical manifestation, neuroradiology, medical management, surgery for intracranial tumours, radiotherapy, chemotherapy, and clinical management of brain tumours. In addition, there are sections devoted to brain and spinal metastases, and primary tumours of the skull and spine. New concepts of molecular oncology for diagnosis and therapy are discussed. Brain cancers (gliomas) were amongst the first neoplasms subjected to systematic genomic and transcriptomic analysis that may guide individualized treatments. In addition to gliomas, rarer type of intracranial tumours are included, such as ependymomas, primitive neuroectodermal tumours, and pineal tumours are also covered.

Abstract OBJECTIVE Idiopathic myelofibrosis is a clonal stem cell disorder that leads to ineffective erythropoiesis accompanied by reactive myelofibrosis (bone marrow fibrosis). As a consequence, extramedullary hematopoiesis characteristically develops. The central nervous system is rarely affected; the spinal canal and the cranial meninges are generally the preferred locations. Extramedullary hematopoiesis within central nervous system primary tumors have already been reported but, to our knowledge, never before in a patient with evidence of idiopathic myelofibrosis. CLINICAL PRESENTATION A patient experiencing generalized idiopathic myelofibrosis developed a hemorrhagic intracranial meningioma containing islets of extramedullary myeloid metaplasia. INTERVENTION The tumor was radically removed through a right frontal craniotomy. After surgery, the patient recovered completely and was discharged with a normal neurological status. After 6 years, the patient is in excellent condition with no sign of recurrence on magnetic resonance imaging scans. CONCLUSION The reasons for this uncommon association are uncertain, but we hypothesize that myeloid islets may be involved in the origin of the tumor as well as in its acute hemorrhagic onset. Moreover, we suggest that in the presence of proven idiopathic myelofibrosis intracranial myeloid metaplasia should be ruled out by appropriate neuroimaging and considered as a potential diagnosis in the presence of brain lesions.

Meningioma is a well-recognized tumor of the central nervous system, but it rarely appears as a primary extracranial tumor of the paranasal sinuses. We report a case of a primary right anterior ethmoid meningioma that resembled a mucocele in its presentation. A primary meningioma can be differentiated from a secondary meningioma in three ways: (1) by observing an intact bony wall of the sinus on imaging or on inspection during surgery, (2) by noting the absence of a simultaneous intracranial meningioma on imaging or on inspection during surgery, and (3) by identifying a bulging of the sinus wall toward the cranium rather than in the opposite direction.

Extensive Damage

With the advent of the space age and the need to determine the requirements for a space cabin atmosphere, oxygen effects came into increased importance, even though these effects have been the subject of continuous research for many years. In fact, Priestly initiated oxygen research when in 1775 he published his results of isolating oxygen and described the effects of breathing it on himself and two mice, the only creatures to have had the “privilege” of breathing this “pure air”.Early studies had demonstrated the central nervous system effects at pressures above one atmosphere. Light microscopy revealed extensive damage to the lungs at one atmosphere. These changes which included perivascular and peribronchial edema, focal hemorrhage, rupture of the alveolar septa, and widespread edema, resulted in death of the animal in less than one week. The severity of the symptoms differed between species and was age dependent, with young animals being more resistant.

Interendothelial Junctions

Studies using mesenteric and ear chamber preparations have shown that interendothelial junctions provide the route for neutrophil emigration during inflammation. The term emigration refers to the passage of white blood cells across the endothelium from the vascular lumen. Although the precise pathway of transendo- thelial emigration in the central nervous system (CNS) has not been resolved, the presence of different physiological and morphological (tight junctions) properties of CNS endothelium may dictate alternate emigration pathways.To study neutrophil emigration in the CNS, we induced meningitis in guinea pigs by intracisternal injection of E. coli bacteria.In this model, leptomeningeal inflammation is well developed by 3 hr. After 3 1/2 hr, animals were sacrificed by arterial perfusion with 3% phosphate buffered glutaraldehyde. Tissues from brain and spinal cord were post-fixed in 1% osmium tetroxide, dehydrated in alcohols and propylene oxide, and embedded in Epon. Thin serial sections were cut with diamond knives and examined in a Philips 300 electron microscope.

Acetylcholinesterase (EC 3.1.1.7) (ACHE) has been localized at cholinergic junctions both in the central nervous system and at the periphery and it functions in neurotransmission. ACHE was also found in other tissues without involvement in neurotransmission, but exhibiting the common property of transporting water and ions. This communication describes intracellular ACHE in mammalian bone marrow and its secretion into the extracellular medium.

Generation of monoclonal antibodies (MAbs) against tissue antigens has yielded several (VC1.1, HNK- 1, L2, 4F4 and anti-leu 7) which recognize the unique sugar epitope, glucuronyl 3-sulfate (Glc A3- SO4). In the central nervous system, these MAbs have demonstrated Glc A3-SO4 at the surface of neurons in the cerebral cortex, the cerebellum, the retina and other widespread regions of the brain.Here we describe the distribution of Glc A3-SO4 in the peripheral nervous system as determined by immunostaining with a MAb (VC 1.1) developed against antigen in the cat visual cortex. Outside the central nervous system, immunoreactivity was observed only in peripheral terminals of selected sensory nerves conducting transduction signals for touch, hearing, balance and taste. On the glassy membrane of the sinus hair in murine nasal skin, just deep to the ringwurt, VC 1.1 delineated an intensely stained, plaque-like area (Fig. 1). This previously unrecognized structure of the nasal vibrissae presumably serves as a tactile end organ and to our knowledge is not demonstrable by means other than its selective immunopositivity with VC1.1 and its appearance as a densely fibrillar area in H&E stained sections.
