    MRI Brain exam
     

    Axial T2 MRI revealed left temporal large Arachnoid cyst.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Acute;

    Axial T2 revealed bright left subdural collection with associated mass effects and midline shift.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Acute;

    Coronal T2 MRI revealed the original Arachnoid cyst and the associated subdural hygroma differentiated by the cortical veins (red arrows) and both exerts CSF intensity pattern.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Acute;

    Coronal T1 MRI with the cortical veins (red arrows) demarcating the borders between the original Arachnoid cyst and the subdural hygroma.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Acute;

    Axial SWI revealed cortical veins traversing the original Arachnoid cyst (red arrows). No evidence of haemorrhagic changes seen.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Acute;

    Axial SWI at the level of the subdural hygroma revealed cortical veins compressed against the brain surface (arrows). No evidence of haemorrhage within the subdural collection.

     
    Area of Interest: Head and neck; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Acute;

    Post Operative CT

    Post management Coronal MPR CT revealed adequate decompression of the subdural hygroma with evacuation of the left subarachnoid cyst.
