. Case 12. The cystic tumor with thin specked capsule is blocking the foramen of Monro. This finding suggests that the tumor is a craniopharyngioma. E. Case 16. The brownish yellow solid tumor (craniopharyngioma) is seen over the foramen of Monro, occupying the anterior half of the third ventricle. Biopsy cup is just pushed out. F. Case 16. Perforation of the septum pellucidum with a cauterizing electrode. G. Case 8. The tumor (pinealoma), finely granular and dark red in color, has occupied the entire posterior half of the third ventricle, compressing the adhesio

spine is removed. The whole procedure can be done through a sublabial incision by the neurosurgeon. The operative field is as wide as in the conventional method. With the proper adjustment of the position of the microscope and with the rotation of the patient's head, the anterior nasal spine does not obstruct the surgeon's view. So far, we have performed this rhinoseptoplastic operation in 45 cases of pituitary adenoma, one case of craniopharyngioma, and one with a sphenoid mucocele. There was no mortality nor any instance of complications such as cerebrospinal

A n intradural pterional or subtemporal approach has customarily been used in the treatment of lesions of the central cranial base, including the superior clival region, parasellar area, and interpeduncular cistern. 1, 3, 4, 13 Despite certain limitations, both strategies have proven versatile in satisfactorily exposing aneurysms of the upper basilar artery, tumors that escape the bounds of the sella, and lesions of the cavernous sinus and orbital apex. However, when lesions such as giant or high-riding basilar artery aneurysms, or large craniopharyngiomas

epithelial and mesenchymal components. Thus, small samples, such as those obtained from biopsy procedures, may lead to a misdiagnosis of squamous cell carcinoma, adenocarcinoma, malignant craniopharyngioma, or esthesioneuroblastoma, resulting in confusion regarding the true incidence of this tumor and its potential treatment modalities. To our knowledge, this is the first case in which the patient presented with symptoms related to the central nervous system. Furthermore, the MR images demonstrated minimal nasal cavity involvement. The treatment of this lesion

enhancement that represented displaced vascular structures. There was no sharp delineation on the posterior margin, suggesting that the lesion had possibly arisen from the medial thalamus. There was no associated hydrocephalus. Preoperative considerations for a lesion in this location included a germ cell tumor, intraventricular meningioma, central neurocytoma, and an intraventricular oligodendroglioma; however, in this case, the imaging findings favored an intraventricular craniopharyngioma. Operation and Postoperative Course The patient underwent a bifrontal
