case_images: CT scan. A Axial and B coronar reconstruction. T: Tumor, SB: Destruction of the sphenoid bone, L: Labyrinth, PB: Destruction of the petrosal bone, M: Occluded mastoid, SS: Infiltration of the lateral wall of the sphenoid sinus, ICA: Internal carotid artery, PS: Infiltration of the parapharyngeal space, TL: Temporal lobe and invasion of the middle fossa, NST: Asymmetry of the neck soft tissue

case_images: Fig1
case_images: Imaging findings showed an expansive tumor infiltrating and destroying the right lateral skull base (Fig. 1).
case_images: MRI scan. T1 with contrast, A and B: tumor extension preoperatively. Tumor (T) infiltrating the temporal and infratemporal fossa, parapharyngeal space (PS) and the middle fossa. Mild upwards compression of the right temporal lobe (TL). Asymmetry of the neck soft tissue (NST). C, D: 4 months postoperatively and E, F: 2 years and 4 months postoperatively no evidence of residual tumor and recurrence after reconstruction of the laterobase (RLB) and partial occlusion of the sphenoid sinus (OSS) with autologous fat. A, C, E: sagittal. B, D and F: coronar

case_images: The tumor was partially composed of cystic/regressive lesions with high contrast media uptake (Fig. 2).
case_images: Operative findings. Total resection via transparotideal-infratemporal approach. PG: Parotid gland, T: Tumor, TBC: Temporo-basal craniotomy, MFD: Dura of the middle fossa, RTM: Retracted temporalis muscle (split), REL: Retracted ear lobe

case_images: Fig3
case_images: We performed a tumor resection via a transparotideal-infratemporal approach, including complete parotidectomy, resection of the zygomatic and the ascending mandibular branch of the facial nerv, evacuation of the infratemporal fossa and radical anterior petrosectomy (Fig. 3).

case_images: Histologically, the tumor was composed of granular variably calcified chondroid matrix with extensive regressive changes and granulation-like tissue reaction associated with calcinosis and crystal deposition (Fig. 4).
