Rarely, hemorrhagic cysts can lead to acute obstructive hydrocephalus or sudden death. We herein report 2 cases and a review literature. We examine a 47-year old male who presented with progressive headache and a 55-year old male who presented with progressive memory disturbance and unsteady gait. Both cases demonstrated typical imaging features of hemorrhagic colloid cyst, and were histopathologically confirmed. Total excision was achieved in both cases with good outcomes. Hemorrhagic colloid cysts are rare; however, bleeding tendencies should be carefully considered in patients with these cysts. The degree of rapidity with which clinical deterioration occurs may play a major role in the preferred treatment approach and subsequent outcomes.
