case_images: Gadolinium-enhanced MRI of the orbital region revealed hypersignals predominantly in the lateral side of the left orbit (red arrow). The optic nerve and extraocular muscle were compressed by the orbital lesion (green arrow). Abnormal signals spread to the eyelid, subcutaneous temporal region, vicinity of the auricle (yellow arrow), scull base on the ventral temporal lobe, meninges, and maxillary sinus (blue arrow). Inflammation of the maxilla spreads to the inside of the orbit and the meninges via the zygoma and temporal bone on the side wall of the orbit.

case_images: The orbito-encephalic MRI with gadolinium enhancement revealed hypersignals predominantly in the lateral left orbit, with extension to the eyelids, temporal subcutaneous area, and vicinity of the auricle (Fig. 1).
case_images: Facial photos. a Redness and tenderness in the temporal region. b Purulent discharge from the left temporal region.

case_images: However, after 2 months, the patient developed redness, tenderness, and pus discharge from the temporal swelling (Fig. 2).
case_images: Plain CT image of the orbital region of the head showed bone destruction in the left frontal bone, zygomatic bone, ethmoid bone, and sphenoid bone (arrows). No bone destruction at the border between the maxillary sinus and the orbit (oval) was observed.

case_images: CT revealed bone destruction in the left frontal, zygomatic, ethmoid, and sphenoid bones, along with swelling of the temporal soft tissue and thickening of the maxillary sinus mucosa (Fig. 3).
case_images: Latest facial photo, simple CT image, and contrast-enhanced MRI image. a Swelling of the left eyelid and temporal region improved. b No progression in bone destruction was observed. c Intraorbital lesion shrank, and abnormal signals in the temporal region improved.
