Computed tomography in primary reticulum cell sarcoma of the brain
DR Enzmann, J Krikorian, D Norman, R Kramer, J Pollock and M Faer
The CT findings in 16 patients with histologically proved primary central
nervous system (CNS) reticulum cell sarcoma (RCS) showed this malignancy to
have predilection for the basal ganglia and thalamus, the periventricular
white matter, the corpus callosum, and the vermis cerebelli. In 43% of
patients with untreated tumor it presented as multifocal lesions; in each
of these patients the basal ganglia were involved in conjuction with
another site. In the other 57% of patients with untreated tumor presenting
as solitary lesions the basal ganglia, the corpus callosum, and the frontal
lobe were sites of predilection. Such solitary lesions may be
indistinguishable from other tumors. Contrast enhancement of RCS was
characteristically homogeneous with rare lucency, even in very large
lesions.
