Subsequent bilateral inferior petrosal sinus sample (BIPSS) was performed for the localization diagnosis [Figure 1]d, which demonstrated adrenocorticotrophic hormone (ACTH) level of inferior petrosal sinus and femoral vein at 0 min were 691.4 ng/L and 162.9 ng/L, at 5 min were 952.2 ng/L and 172.3 ng/L, respectively; GH level of inferior petrosal sinus and femoral vein at 0 min were 6.34 ng/ml and 3.88 ng/ml, at 5 min were 3.7 ng/ml and 2.38 ng/ml, respectively.
It is surrounded by various clinically significant structures, including the cochlea, middle ear, eustachian tube, gasserian ganglion, geniculate ganglion, greater superficial petrosal nerve, and jugular fossa.
Results: Petroclival region can be accessed through following approaches: petrosal, anterior and posterior combined approach, supra and infratentorial combined presigmoid approach, orbito-zigomatic infratemporal approach, suprameatal intradural retrosigmoid approach, pterional approach, retromastoid approach, subtemporal approach and combined subtemporal retromastoid approach:
It is accepted as the first landmark at combine petrosal approaches for the cranial basis, and as the respectable landmark for the duramater of posterior fossa lying under it (Day & Tschabitscher; Mwachaka et al.; Sripairojkul & Adultrakoon; Tubbs et al., 2009).
This subgroup also included intratympanic, attic, and hypotympanic meningiomas and those of the geniculate ganglion, the sulci of the greater and lesser petrosal nerves, the jugular foramen, the internal acoustic meatus, the mastoid process, and the petrous bone.
