Pachymeningitis

At the autopsy are found hyperemia of the arachnoid, and slight chronic leptomeningitis and pachymeningitis. ❋ Unknown (1896)

_ -- In some cases the cord and nerve roots are pressed upon by an œdematous swelling of the membranes; in others, the tuberculous process attacks the dura mater and gives rise to the formation of granulation tissue on its outer aspect -- _tuberculous pachymeningitis_. ❋ Alexander Miles (1893)

In the majority of cases, however, suppuration occurs between the dura and the bone -- _suppurative pachymeningitis_ -- and leads to the formation of an _extra-dural abscess_ (Fig. 192). ❋ Alexander Miles (1893)

The layer of the dura in contact with the affected portion of bone is inflamed, thickened, and covered with a layer of granulations -- _external pachymeningitis_ -- and between it and the bone there is an effusion of fluid. ❋ Alexander Miles (1893)

He believes it to consist in a pachymeningitis combined with a certain degree of sclero-gliosis of the periphery of the cord. ❋ Alexander Miles (1893)
