XXXX : a correlative clinicopathological and radiological study of ten surgically treated cases with follow-up.

@entity1 @entity410 @entity5 @entity730 @entity7667 @entity463
@entity7667 are rare @entity5 of the central nervous system containing neoplastic ganglion and low grade glial cells. In studying 10 surgically treated cases, we evaluated the clinical, pathological, radiological, and immunocytochemical features, with follow-up. Ranging from 18 to 58 years in age, 7 @entity1 were @entity1 , and 3 were @entity1 . The most common presenting symptom was @entity410 . Computed tomographic scan showed a low density enhancing mass in 8 and @entity730 in 5. Six had minimally abnormal vascularity on angiography. Seven @entity1 had total and 3 had subtotal resections of the @entity5 . The temporal lobe was the location of the @entity5 in 6 cases. All of the cases met the histological criteria of Russell and Rubinstein for @entity7667 . Four @entity1 received postoperative radiotherapy because of subtotal resection or aggressive histological makeup. On follow-up, from 2.5 to 7 years, 8 @entity1 are alive and @entity5 -free, and 7 are also @entity410 -free. Two died after operation: one immediately and the other of a @entity463 that developed 5 years later. Our study confirms that @entity7667 is a distinct histological entity, anatomically localized, with characteristic clinical and radiological findings and long term survival. Aggressive histological makeup is not a definite indication of malignant potential. The definitive role of follow-up radiotherapy for this @entity5 needs further study. Malignant evolution is rare, but warrants follow-up.
