The mindmaps below provide a summarised overview of the main pathologies involving the CNS.

These are not comprehensive, but, rather provide a big picture view.

    Hi Dr Nga!

    Could I find out why a venous thrombus in the CNS would result in pale/bland infarct, when elsewhere in the body it usually results in congestion (red)? Thank you! 🙂

      Hello,

      Venous thrombosis in the brain certainly can lead to haemorrhage, but still in the context of obstruction and ischaemia, i.e. the primary pathology is an occlusive one rather than cerebral haemorrhage. Ischaemia due to vascular occlusion can result in either bland or haemorrhagic infarcts. The arterial imflow is also compromised when there is a venous occlusion, hence the ischaemia. According to the literature, about half of venous thrombosis cases show evidence of haemorrhage.
      I hope this helps clarify!
