Fundamental to the frozen section diagnosis of intraspinal disorders is the pathologist's familiarity with this region's natural partition into three compartments: the spine and epidural space, the intradural-extramedullary chamber, and the intramedullary structures of spinal cord and filum terminale. Each of these three divisions contains characteristic anatomic structures and, for this reason, is the locus of distinctive pathologic entities. Therefore knowledge of a lesion's precise anatomic origin focuses the pathologist's attention on a limited differential diagnosis and facilitates recognition in frozen section.
