| ABSTRACT |
|
We present a series of 42 patients with the lateral ventricular mass lesions who underwent operative removal between 1979 and 1992 at the Seoul National University Hospital. These lesions included 29 tumors, 10 benign cysts and 3 arteriovenous malformations. There were 20 lesions in the trigone, 14 in the frontal horn, 6 in the body, and 2 in the temporal horn. Together with the age of the patient, the location in the lateral ventricle and the CT or MR patterns, the range of the differential diagnosis of the lesions can be narrowed. The mass were removed by various surgical approaches;11 by the middle frontal gyrus, 10 by the superior parieto-occipital, 13 by the middle temporal gyrus, 4 by the anterior transcallosal, 2 by the posterior transcallosal and 3 by the combined approaches. The superior parieto-occipital approach left postoperative morbidities in 64% and other approaches in 20 to 25% of the cases. These morbidities included hemiparesis, hemianopsia, aphasia, memory distubance and seizure. Most hydrocephalus disappeared without the shunting procedure after removal of the lateral ventricular mass. The high frequency of postoperative complications in the superior parieto-occpital approach require meticulous consideration in the selection of this approach. |
