“…12,15,16) The occipital transtentorial approach is suitable for the latter tumors because of the higher projection in the sagittal plane. 5,13,15,16) However, the occipital transtentorial approach lacks the midline trajectory because the anatomical midline is blocked by the superior sagit-H.

Fig. 1 Preoperative T 1 -weighted magnetic resonance images with gadolinium revealing a pineal region mass with multiple components. left: Axial view, right: sagittal view. AbstractA 15-year-old boy with a large pineal region mass was admitted to our institute. The tentative diagnosis was mixed germ cell tumor. Tumor resection was carried out via a transverse sinus-tentorium splitting approach. The tumor tissue was completely resected, and no operative complication other than transient vertical gaze paresis was noted. The histological diagnosis was mixed germ cell tumor composed of mature and immature teratoma, germinoma, and embryonal carcinoma. After three courses of chemotherapy, the patient underwent external irradiation. He remained asymptomatic with no signs of recurrence 42 months after the surgery. The combination of the infratentorial supracerebellar approach and the occipital transtentorial approach provides excellent views and work space above and below the tentorial notch. Transverse sinus section is not mandatory for this approach, but sectioning of the unilateral transverse sinus and the tentorium along the rectal sinus allows retraction of the falx and the underlying brain to the opposite side. Thus, a much wider horizontal and vertical projection is obtained. This approach enables safer and more extensive tumor removal for large pineal region tumors.

Direct surgical resection of pineal region tumors has become safer, more effective, and now plays an essential role in their management. Tissue diagnosis allows for the initiation of appropriate therapies and resection can be curative or improve the efficacy of adjuvant therapies. Several approaches have been reported. Based on our operative experience with 57 patients over a 20-year period, we conclude that the Infratentorial Supracerebellar and Parieto-Occipital Paramedian Transtentorial approaches provide excellent exposure while allowing minimally invasive, relatively low risk access to the majority of pineal region tumors. Indications, positioning, techniques, advantages, and disadvantages are discussed. A review of other approaches, pertinent historical remarks, and a discussion of the role of surgery in the contemporary management of pineal region tumors are presented.
