Early urgent cranioplasty for symptomatic hygroma: Report of two cases.

Following craniectomy, hygromas are relatively common. While many cases resolve spontaneously, some patients develop neurologic deficits. Management of symptomatic hygromas often involves shunting or drainage. We present two patients who three weeks after decompressive hemicraniectomy developed declining neurologic status secondary to enlarging hygroma. Failing conservative management, both were treated with urgent cranioplasty and returned to neurologic baseline. Early cranioplasty may be safe and effective for symptomatic collections.
