OBJECTIVE: Investigating the structure, contents, location, and borders of interpeduncular cistern and its communications with adjoining cisterns. MATERIALS AND METHODS: Microsurgical anatomy of the interpeduncular cistern was studied in 14 adult cadaver brains, using a surgical microscope(x3 to x40 magnification). RESULTS: The interpeduncular cistern was divided into two portions: superficial (free) and deep (vascular). The superior wall of interpeduncular cistern was separated into the hypothalamic and mesencephalic part. It has communication with ambient, prepontine, carotid, cerebellopontine, oculomotor, and crural cisterns. CONCLUSION: The interpeduncular cistern is a compound bulk structure. This classification is necessary for the quantitative and qualitative study of the interpeduncular anatomy. Also, it is necessary to neurosurgeons for the guiding line in this region.
