Objective:
To study the clinical characteristics, neuroimaging presentations, operative warming events and the results of surgical treatment of meningioma of the falco-tentorial junction.
Methods:
The clinical data of 14 patients with meningioma of the falco-tentorial junction were retrospectively analysed. Preoperative examinations included head CT in all patients, DSA in 10, MRI in 6, and MRA in 2. 10 patients was operated on via suboccipital transtentorial approach, of which, operated-side-up position in 7 patients, three-quarter prone operated-side-down position in 3. Three 3 patients was operated on via trans-infratentorial-supracerebellar approach. One via trans-lateral-ventricle trigone approach.
Results:
Of 14 patients, 12 received total removal of meningioma and 2, subtotal resection. Intracerebral hematoma occurred postoperatively in 2 patients and, intratumoral-residual-cavity hematoma in 1. Two patients' hematomas were eliminated, and another patient's hematoma was conservatively treated. Average follow-up period was 4.5 years. All patients resumed their normal work and study. One patient had permanent homonymous hemianopsia, and one had trochlear paralysis.
Conclusions:
Meningiomas of the falco-tentorial junction were operable. With some acceptable morbidity, perfect surgical results can be obtained.
