illness. For this reason, we decided to evaluate IC in a
group of patients with multiple sclerosis (MS). The
results were compared with the findings in other patients with amyotrophic lateral sclerosis (ALS) and
senile dementia of the Alzheimer type (SDAT), respectively.
Material a n d Methods
Thirty-eight patients with definite MS, 14 male and 24 female, were examined. The diagnosis was assessed by clinical evaluation and laboratory investigation. In particular,
serum and CSF radial immunodiffusion (according to Mancini et a1 [8]) was performed in each case, and the IgG index
according to Link [7] and daily intrathecal production of
IgG [9]were calculated. The results of IC performed in 15
ALS patients and 14 patients with SDAT were compared as
controls.
IC was carried out with a routine lumbar puncture.
9Tc-DTPA solution, 20 to 30 pCi per kilogram of body
weight (total volume, 1 to 1.5 ml), was introduced into the
spinal subarachnoid space. Radiography was performed 1,
2, 6, and 24 hours after the injection. The cisternographic
pictures were classified according to recent literature [101
as follows:
Normal pattern: uninterrupted flow from the lumbar subarachnoid space into the basal cisterns, around the
brainstem, through the tentorial notch into the sylvian
cisterns, and over the convexities of the hemispheres to
the parasagittal regions. No ventricular activity is observed.
Mixed pattern: filling of the ventricular system 4 to 6 hours
after lumbar injection. At 24 hours ventricular activity
may still be seen, but normal flow over the hemispheric
convexities is also observed.
Ventricular pattern: ventricular influx both early and late as
long as radioactivity can be detected. Although there is
no flow of isotope above the tentorial notch, one or both
sylvian cisterns may occasionally be visualized; flow over
the hemispheres to the parasagittal regions is not observed.
The cisternographic patterns in the MS patients were
correlated with the clinical and laboratory variables of patient age, IgG index according to Link, and daily intrathecal
production of IgG according to Tourtellotte.
Computed tomographic (CT) studies were available for
15 of the patients with MS and all 14 with SDAT.
Results
In 18 (47%) of the 38 MS patients examined, IC
showed an abnormal picture of mixed type. A mixed
pattern was also detected in all SDAT patients. None
of the 15 ALS patients showed an abnormal IC pattern. The four groups (MS with abnormal IC, MS
with normal IC, ALS, and SDAT) were compared according to patients’ mean age, mean IgG index, and
mean rate of IgG synthesis in the central nervous
system (Table). The group of MS patients with abnormal IC differed significantly from the others in
their IgG index and rate of IgG synthesis in the central nervous system.
CT scan of the brain was performed in 15 of the 38
MS patients and the findings compared with those
obtained by CT study of the 14 SDAT patients. CT
was carried out in 5 MS patients with an abnormal IC
picture. In 2, the scan showed enlargement of the
cerebral ventricles, mostly of the lateral. One of
these CT scan pictures is reproduced in Figure 1 and
is compared with the cisternogram, Figure 2, obtained in the same patient. In the other 3 MS patients
with abnormal IC only slight cortical and subcortical
atrophy was observable, similar to that seen in 3 of 10
MS patients with normal IC in whom CT was carried
out. In the other 7 patients no abnormality of the CT
picture was found. CT study in all SDAT patients
showed cortical and subcortical atrophy.
Discussion
Some considerations should be pointed out in relation to the significance and diagnostic limits of the
technique of IC using @ T cas the marker. The abnormal patterns, particularly the so-called mixed
type, should no longer be considered of specific
diagnostic value [5, 61. It appears that an abnormal
pattern may be produced by different physiopathological mechanisms that are not yet completely
clarified. Moreover, similar pathological patterns
can be detected in different clinical conditions.
Brief Communication: Bartolini et al: Isotopic Cisternography in MS 487
F i g 1 . CT scan i n the MS patient whose cisternographicpictures are shown in Figure 2 demonstrates moderate dilatation
of the lateral ventricles and signs of mild subcortical atrophy.
We found an altered isotopic pattern of mixed type
in 47% of our MS patients and in all SDAT patients
subjected to this investigation. Among the possible
mechanisms of the altered IC in MS, the following
may be considered. First, the abnormal pattern may
be due to an inflammatory alteration of the subarachnoid spaces of the cerebral convexities. There is
pathological evidence of chronic inflammation of the
leptomeninges, localized mainly to the subarachnoid
spaces of the cerebral convexities, in the active forms
of MS [l]. These alterations may affect the normal
efflux of CSF from the ventricular system to the sites
of reabsorption in the cranial vault. And second, an
altered IC with a pattern of mixed type may be related to increased transependymal CSF reabsorption
as a consequence of alteration of the ependyma, the
periventricular white matter, or both. This abnormal
reabsorption may lead to inversion of the normal
flow gradient from the ventricles to the subarachnoid
space. The main periventricular distribution of demyelination in MS is well known [l].
Our results indicated a significant correlation between abnormal IC patterns and IgG produced in
situ. However, this finding also suggests that CSF
IgG levels may be influenced by CSF dynamics and

may correlate with the reabsorption rate of CSF
proteins at drainage sites.
Further studies in MS, using more sensitive
isotopic techniques and CT with metrizamide together with determination of IgG turnover with
isotope-marked IgG, seem necessary in order to
confirm and clarify our data in MS patients.

A 53-year-old man presented with a lumbosacral
polyradiculoneuropathy and developed fluctuating
encephalopathy suggestive of multifocal small vessel
disease. Postmortem examination demonstrated multifocal vascular occlusions by undifferentiated cells
confined to the intravascular space. Extravascular
spread was found only in spleen and liver. The presence of lysozyme and absence of factor VIII in the
cytoplasm of the malignant cells confirmed their histiocytic nature. This patient had an unusual intravascular form of malignant histiocytosis that must be
included in the differential diagnosis of multifocal
vascular disease.

Widespread vascular occlusion by malignant cells is
not often considered in the diagnosis of multifocal
nervous system disease. Rare examples of neoplastic
angioendotheliosis [2, 12, 14, 181 and tumor emboli
[6] have been considered to produce signs by this
mechanism.
A patient with progressive polyradiculoneuropathy
and fluctuating encephalopathy was found at autopsy
to have multiple small vessel occlusions by malignant
histiocytes. Malignant cells were found within vascular lumens without parenchymal involvement of any
organ except the spleen and liver.
