Rs. Glasser et al., DELAYED OCCURRENCE OF CEREBELLAR PLEOMORPHIC XANTHOASTROCYTOMA AFTER SUPRATENTORIAL PLEOMORPHIC XANTHOASTROCYTOMA REMOVAL - CASE-REPORT, Journal of neurosurgery, 82(1), 1995, pp. 116-118
The authors report the case of a 36-year-old woman who underwent gross
total resection of a right cerebellar pleomorphic xanthoastrocytoma w
ith atypical features. She had undergone surgery 16 years previously f
or what was thought to be a right frontal glioblastoma multiforme. In
retrospect, based on the histopathology and the clinical course, both
lesions were considered to represent atypical variants of pleomorphic
xanthoastrocytoma. This report examines the histological and clinical
characteristics of this posterior fossa lesion, which exhibited histol
ogically malignant features but has run a relatively indolent course.
