Many published literature sources have described the histopathological characteristics of post-traumatic syringomyelia (PTS). However, three-dimensional (3D) visualization studies of PTS have been limited due to the lack of reliable 3D imaging techniques.

Central nervous system tuberculosis (CNS-TB) takes three clinical forms: meningitis (TBM), intracranial tuberculoma, and spinal arachnoiditis. TBM predominates in the western world and presents as a subacute to chronic meningitis syndrome with a prodrome of malaise, fever, and headache progressing to altered mentation and focal neurologic signs, followed by stupor, coma, and death within five to eight weeks of onset. The CSF formula typically shows a lymphocytic pleocytosis, and low glucose and high protein concentrations. Read More
