Delayed Traumatic Intracerebellar Hematoma: Correlation Between the Location of the Hematoma and the Pre-existing Cerebellar Contusion

This is the authors' abstract. We don't add key points for this paper.

A rare case of delayed traumatic intracerebellar hematoma (DTIC1H) in a 54-year-old male achieved an excellent outcome without surgery. Analysis of this case and other reported cases suggests that DTIC1H occurs in two types: Group I with hematoma developing in previously contused areas, and Group II with hematoma developing in areas appearing normal on the initial computed tomographic scan. Group I hematomas occurred in the cerebellar cortex, but Group II hematomas occurred in the subcortical region or vermis where direct impact is less likely to have an effect. This suggests different mechanisms of development for DTIC1H.
