Text Appearing Before Image:
rtion of the cord was contracted, and stained a uniform light yellow.In the higher sections (Fig. 167 a-e) up into the cervical cord the usual picture ofascending degeneration in the posterior columns as well as in the periphery of thelateral columns was recognized and could be noted by the paler stain. Besides a focusof softening about the size of a millet seed (Fig. 167 e) was found from the 8th dorsalsegment, extending downward in the left posterior column near the commissure beingdistributed to the dorsal cord, and at the 4th dorsal segment widening into a cavity 400 MYELITIS (167 d) thence extending over the middle of both posterior columns and filled withyellowish masses. This tubular focus terminated in the lower cervical cord. Leyden, upon histologic examination (according to Nissl, Marchi, Weigert, etc.),was unable to find nerve fibers or ganglion cells in the lower dorsal, lumbar or sacralcord; the tissue in the entire transverse section consisted of numerous granular cells,

proliferated glia meshes, myelin granules and a few hematoidin crystals. Only in afew longitudinal sections were there scant fragments of destroyed axis cylinders andmedullary sheaths. The pia mater was greatly contracted, the posterior roots wereonly in part destroyed, while the anterior roots were transformed into an almost com-plete dense, fibrillary tissue. This destruction of the spinal cord continued in thelateral columns to the 8th dorsal segment, while in the posterior columns it could befollowed, in the form of a peg-like focus to the lower cervical cord. The largest focus THE CLINICAL PICTURE OF DORSAL MYELITIS 401 also situated in the 4th dorsal segment (Fig. 167 d) consists of granular cells, remainsof medullary sheaths and glia fibers, the latter becoming denser around the focus.With this there is the usual ascending degeneration in the posterior columns (Fig.167 ci-e) and in the lower border zone (cerebellar lateral column, Gowers bundle).The muscles of the leg were in a
