✓ A rare case of intradural chordoma is described. The literature contains seven examples of intradural extraosseous chordoma, all reported in a ventral location. This is the first reported case of a primary intradural chordoma distant from the clivus and involving both the supra- and infratentorial compartments.

Abstract The falx cerebelli is a small sickle-shaped fold of dura mater below the tentorium cerebelli, which projects forward into the posterior cerebellar notch. We report a rare case of 28 year female presented with the history of headache of six months duration off and it increased in severity and frequency over last 15 days. Imaging findings were suggestive of meningiona arising from the falx cerebelli. The lesion could be excised totally and safely.

✓ The authors describe a 37-year-old man with the classic clinical features of Hand-Schüller-Christian disease. He presented with symptoms of increased intracranial pressure due to obstructive hydrocephalus secondary to a huge xanthogranuloma involving falx cerebri and tentorium cerebelli. Immunohistochemical and ultrastructural studies failed to demonstrate Langerhans histiocytes, however. The implication of this finding is discussed in light of the recent relevant literature.

The Central Nervous System

Sarcoidosis is a systemic granulomatous disease with unknown cause, which very rarely occurs exclusively in the central nervous system. The authors performed biopsy sampling of a mass that developed in the left tentorium cerebelli that appeared to be a malignant tumor. The mass was diagnosed as a sarcoid granuloma, which was confirmed with the onset of antibody reaction product against Propionibacterium acnes. Findings suggesting sarcoidosis to be an immune response to P. acnes infection have recently been reported, and they give insight for diagnosis and treatment of this disease. The authors report the possible first case that was confirmed with P. acnes infection in a meningeal lesion in solitary neurosarcoidosis.

✓ The authors report a variety of arrangements of the venous channels comprising the straight sinus (sinus rectus) and its connections during a continuing study of the cerebral sinuses and their tributaries. In approximately 85% of 131 specimens of dura mater with enclosed venous sinuses derived from fresh cadavers, the straight sinus was represented by a single midline tentorial channel whereas in the remaining 15%, segments of it were doubled and in a few, tripled. In addition to these aberrations in the development of the main trunk of this sinus, the venous patterns at the junctions of the inferior sagittal sinus, vein of Galen and straight sinus showed comparable developmental inconstancies. Also in no specimens were the patterns of venous channels in the leaves of the tentorium cerebelli alike. The course, size, and connections of all the tributaries of the straight sinus have been studied and consideration given to their potentials as collateral pathways in the event either the vein of Galen or the straight sinus itself were occluded.

Recent developments in neuron recording techniques include the invention of some fragile electrodes. The fragility of these electrodes impedes their successful use in deep brain recordings because it is difficult to penetrate the electrodes through the dura mater, especially the tentorium cerebelli (TC) enclosing the cerebellum and brain stem. This paper reports a new method to pierce the TC for inserting fragile electrodes into the inferior colliculus of rhesus monkeys. Briefly, a unique tool kit, consisting of needles with sharp tips, a guide tube and an “impactor,” was used in a multistep protocol to pierce the TC. The impactor provided a brief force that quickly thrusts the needles through the meninges without causing significant damage to the brain tissue under the TC. Using this novel approach, tetrodes were successfully implanted into the inferior colliculus of a rhesus monkey and neuronal discharge signals were recorded. This method, which is simple, convenient and economical, allows neurophysiologists to study the electrophysiological characteristics of deep brain structures under the TC with advanced, albeit fragile, electrodes.
