We report a very rare case of high division of sciatic nerve ' of different types ' on the either sidse of 43 years old male Sudanese Cadaver with unilateral right divided piriformis sciatic nerve on the either sides divided in with the pelvis into two terminal branches: common fibular nerve and tibial nerve and entered into the gluteal region .on the Rt side there is divided piriformis ' with superior large and inferior small parts', common fibular nerve pass between these 2 heads of piriformis and tibial nerve pass bellow the superior gemillus muscle on the left side both branches of sciatic nerve : common fibular nerve and tibial nerve pass bellow the piriformis muscle ' normal piriformis on the left; is rare to find different types of bilateral high division of sciatic nerve in the same Cadaver. On the right side also we report a very rare and unusual finding which is origin of descending genicular branch from the tibial nerve at higher level just as it is emerge from the pelvis bellow superior gemillus muscle. To our knowledge there is no literature reporting this type of variation.
