case_images: Three-dimensional T2-weighted images (A-F) demonstrating the AICA (A-F, black arrow), the VII/VIII complex (A-C, green arrow), and the vagus nerve (D, black arrow).

case_images: Three-dimensional imaging, performed with 3D Slicer, clearly revealed a neurovascular contact between the facial-vestibulocochlear nerve complex (VII/VIII complex) and the anterior inferior cerebellar artery (AICA) (Figures 1A-C, 2). The AICA continued downward to make close contact with the vagus nerve (Figures 1D-F, 2).
case_images: Three-dimensional reconstruction of MRI images according to the criteria for ICHD-3 intermediate neuralgia of the International Classification of Headache Disorders (Table 1). The diagnosis of intermediate neuralgia was made based on the patient's history, imaging, and physical examination. Specifically, an operative picture that shows neurovascular compression on the nervus intermedius would help establish this diagnosis.

case_images: Intraoperative views under the microscope. (A) The ACIA (A-D, red arrow) had insinuated itself in the middle of the VII/VIII complex; (B) the AICA was lifted, and the Teflon felt was placed between the vessel and the VII/VIII complex; (C) the AICA near the caudal group of nerves; (D) no significant vascular compression of the trigeminal nerve root.

case_images: The exploration continued along the AICA toward the pedicle, and a vascular collateral was seen to form a close relationship with the cranial nerve of the caudal group. The Teflon felt was placed dorsally between the arterial vessel and the nerve of the caudal group (Figure 3).
