Sinking Skin Flap Syndrome: Phenomenon of Neurological Deterioration after Decompressive Craniectomy

Sinking skin flap syndrome is rare phenomenon that occurs in patients with large craniectomies. Alteration in normal anatomy and pathophysiology can result in wide variety of symptoms including altered mental status, hemodynamic instability, and dysautonomias. Management is largely conservative. We here present a case of a patient with large craniectomy who was admitted to our hospital with pneumonia. Later on, he developed worsening mental status and CT head revealed sinking skin flap with significant midline shift. This is a very rare case of neurological deterioration after craniectomies, commonly known as sinking skin flap syndrome. To our knowledge, only few cases have been reported so far.
