title: [Clinical value of lumbar tap in the diagnosis of obliteration of vertebral canal by intraspinal tumors].
abstract: The author analyses the clinical data and pathological manifestations in 29 cases of intraspinal tumours in which the results of preoperative lumbar tap were equivocal or excluded presence of vertebral canal obliteration. On the other hand, myelography showed presence of complete or incomplete contrast stop at the level of the tumour, despite misleading information of the diagnostic lumbar tap.
