OBJECTIVE: Growth patterns of @entity1653 are related to the @entity45541 . Localization and surgical @entity146 are decisive for the outcome to be expected. @entity1 AND METHODS: n = 25 @entity1 (22 f, 3 m), aged from 26-77 (mean: 56.4) years underwent microsurgical removal of their tentorial @entity1653 . @entity5 size was as follows: n = 11 < 3 cm, n = 6 3-5 cm, n = 8 > 5 cm. The median of the preoperative Karnofsky scores was 90. The operative approaches chosen were suboccipital in n = 14, subtemporal in n = 6, occasionally a combined supra- and infratentorial approach was chosen. Data regarding surgery, histology and postoperative course were available through the @entity1 's charts and through outpatient clinic. RESULTS: n = 20 (80%) of the @entity5 were rated WHO grade I, n = 5 (20%) WHO grade II. @entity5 removal according to Simpson was degrees I in n = 9 (36%), degrees II in n = 14 (56%), degrees III in n = 2 (8%). Mortality was 0%. In n = 6 @entity1 (24%) neurological worsening, mainly due to transient @entity129 was noted. @entity532 (CSF @entity292 , wound healing problems) occurred in n = 5 @entity1 (20%). The median of the postoperative Karnofsky scores on last follow up was 90 after a median of 41.9 months. Two @entity1 (8%), one of whom underwent reoperation developed @entity5 recurrency during follow up. CONCLUSIONS: @entity51 following microsurgical @entity1653 are transient in the majority of @entity1 . The apparently high rate of incomplete @entity5 resection (app. 60% Simpson grades II and III) is due to the close topographical relationship of these @entity5 with important neurovascular structures. Thus, the operative strategy should not be excessively aggressive, but rather take into account the option to observe @entity41 or to apply additional stereotactic convergent beam radiation in selected cases.
