Object. The authors conducted a study to examine the detailed anatomy of the denticulate ligaments and to assess their classic role in spinal cord stability within the spinal canal. Methods. Detailed observation of the denticulate ligaments in 12 adult cadavers was performed. Stress was applied in all major planes to discern when the ligaments would become taut, and at the same time, gross motion of the cord was observed at sites distal to the stresses applied. Tension necessary for avulsion of the ligaments in various areas of the spinal cord was also measured. Conclusions. These results show that the denticulate ligaments do not inhibit cord motion to such discrete areas of the cord as was once thought. The authors have determined that the ligaments are stronger in the cervical region and that they decrease in strength as the spinal cord descends. These findings are demonstrative of the denticulate ligaments being more resistant to caudal compared with cephalad stresses in the cord. Anterior and posterior motion is constrained by these ligaments but to a limited degree, especially as one descends inferiorly along the cord. Further embryological and functional studies of these ligaments is needed in non—formalin fixed tissues.

✓ This 54-year-old man with a history of right-sided malignant mesothelioma presented with signs of a partial spinal cord syndrome. The tumor had invaded the lower trunk of the brachial plexus and spread along the T-1 nerve root beneath the arachnoid onto the spinal cord itself. Mesothelioma, despite its known predilection for local spread, is rarely encountered within the spinal canal. Neurotropism is commonly encountered in facial malignancies; however, it has never been reported to affect the brachial plexus and spinal cord.

✓ A case of spinal canal obstruction secondary to a ganglion cyst is reported. The clinical aspects and the pathological findings are described, and the pathogenetic theories related to the origin of ganglion cysts are reviewed. This case seems to support the origin of ganglion cysts of the spinal canal from the facet joints. A review has not disclosed any similar cases in the English literature.

✓ This report describes the unique case of a child born with paraplegia and a neurogenic bladder who was found to have a dysplastic, nonossified T-12 vertebral body, midline fusion of the T-12 neural arches, obliteration of the spinal canal at T-12, and an extraspinal thecal sac in the T11—L1 region. Neural tissue was focally absent from T9–12, but neural structures above and below were preserved. Narrowing of the thecal sac on myelograms and sagittal magnetic resonance images signifies in utero focal infarction of the spinal cord after neurulation but before formation of the posterior half of the spinal canal. The infarction resulted in severe focal narrowing of the thecal sac from T10—L1, resembling a premature and duplicated filum terminale; to denote the radiographic appearance of these anomalies, the authors have coined the term “filum intermedium” sign. The extremely unusual radiographic findings in this child illustrate the important interactions between neural tube, neural crest, and somite in the development of the spinal cord and spinal column. Correlation of the radiographic findings with the embryological differentiation and migration of these structures suggests that the spinal anomalies were caused by a focal insult, probably vascular in origin, occurring between the sixth and eighth weeks of gestation. The identification of a focally narrowed thecal sac and spinal cord (the “filum intermedium” sign) localizes the time of the insult to between the first and third month of gestation, and therefore is a useful marker in understanding developmental malformation of the spinal cord.

✓ Fibrinolytic activity (caused by a plasminogen activator) in the spinal cord was highest in the rat, lowest in the rabbit, and intermediate in the guinea pig. In all species the activity was highest in relation to the pia mater. The central spinal canal was active in the rat and the rabbit, but mostly inactive in the guinea pig. Foci of activity were more numerous in the gray matter than in the white matter corresponding to the greater vascularity of the former. In all species ability to inhibit plasmin was related mainly to the gray matter, with an additional area related to the dura mater. The high fibrinolytic activity of the spinal leptomeninges may play a role in the pathogenesis of hemorrhagic processes related to the spinal cord.
