Conditional Query to Get full graph

I have re format the case for better understanding :

GRAPH :

		India  > hasRegion > East > hasCity > Kolkatta
		India  > hasRegion > West > hasCity > Pune
		India  > hasRegion > West > hasCity > Mumbai 
		India  > hasRegion > West > hasCity > Nagpur
		India  > hasRegion > RegionWest > hasCity > Nagpur

		RegionWest > hasPivotNode > West

Cases :

		Case1 : Cities of region RegionWest : 
		   RegionWest > hasPivotNode > (Found) West > hasCity ?
		   Expected Result :- Pune, Mumbai, Nagpur
						   
		Case2 : Cities of region East : 				   
		   East > hasPivotNode > (Not Found) East > hasCity ?
		   Expected Result :- Kolkatta

I need single conditional query for both of the above cases.

Note : I don’t have any scope to re model the graph.
