ABSTRACT
We have analysed 111 cases of subdural hygroma that were development after various neurosurgical conditions including head injuries. The results were summarized as follows. 1) The peak incidence was the age of 50's and occured most frequently in male. 2) Causes were head injuries(91 cases), traumatic intracranial hematoma removal(10 cases), operation for intracranial aneurysms(4 cases), hypertensive intracerebral hemorrhage evacuation(2 cases), ventriculoperitoneal shunt(2 cases), brian tumor removal(1 cases), arachnoid cyst excision(1 cases), and cerebral infarction(1 cases). 3) Acute subdural hematoma was most often associated with complex subdural hygrom. 4) Clinical manifestations were headache, altered mental state, disorientation, nausea in order. 5) Operation were underwent in 27 cases and surgical complications were reaccumulation and pneumocephalus in order. 6) Mortality rate was 6.3%. 7) The prognois of the simple hygroma was very good, but the complex was not.

Authors report a case of giant mucocele at frontal sinus. It was so large that almost whole portion of ipsilateral frontal lobe was compressed. Nevertheless presenting symptom was exceptionally trivial. With brief review of literatures, we discuss the etiology, pathogenesis, and so on.
