Transcalvarial herniation through a decompressive craniectomy calvarial defect secondary to a contralateral subdural hygroma
Decompressive craniectomies are lifesaving surgeries frequently done to reduce intractable raised intracranial pressure (ICP) of varied etiologies. The procedure while effective in reducing raised ICP is fraught with complications both in the short and in the long term. One such complication is an ipsilateral subdural hygroma which develops over the edematous brain under the scalp flap and adds to the morbidity of the procedure by adding pressure to the damaged brain and retarding recovery. We present an unusual case where, the subdural hygroma developed on the contralateral side and was pushing the brain out of the Calvarial bony defect. This location and action are both not documented in literature thereby making this report novel and interesting.
