case_images: Above: A 31-year-old male presented with progressive ptosis and hypoglobus of left eye. Below: Two weeks status postorbitotomy and excisional biopsy of the orbital mass, there is the resolution of ptosis and hypoglobus

case_images: In inspection, protrusion of the supra-temporal area of the left upper lid and inferior displacement of the globe were seen [Figure 1]. Postoperation, the ptosis and globe displacement was resolved [Figure 1].
case_images: Case 1: Axial (a), coronal (b), and sagittal (c) orbital computed tomography scan demonstrating osteolytic mass lesion (white arrow) arising in the left frontal bone with extension into the orbit. H and E pathology slide at x100 (d), note disposition of cholesterol crystals and hemosiderin deposits

case_images: Orbital CT scan showed a cystic lesion in the superotemporal orbit with erosive bony expansion to the superotemporal orbital wall [Figure 2a-c]. Histopathological analysis revealed fibroconnective tissue with cholesterol clefts surrounded by granulomatous inflammation with a predominance of foreign body giant cells and blood-derived debris and absence of endothelial lining [Figure 2d].

case_images: Examination revealed 4 mm of proptosis and hypoglobus and limitation of up gaze [Figure 3].
case_images: Case 2: Axial (a), coronal (b), and sagittal (c) orbital computed tomography scan showing a cystic lesion (white arrow) in the superotemporal orbit with an associated erosive bony expansion of the superotemporal orbital wall. Coronal T1-weighted magnetic resonance imaging (MRI) (d) showing an intraorbital mass (white arrow) with high internal intensity. Sagittal T2-weighted MRI with gadolinium (e) demonstrating a cystic lesion (white arrow) with high internal intensity in the superotemporal orbit. H and E pathology slide at x400 (f); note disposition of cholesterol crystals and hemosiderin deposits

case_images: Orbital CT scan showed an 8 mm x 11 mm intraorbital well-demarcated mass in the supratemporal area with expansion to the frontal and temporal bone and posterior pressure on the globe [Figure 4a-c]. In orbital MRI a hyperintense intraorbital mass was seen in T1 and T2 weighted images placed in the supratemporal area of the orbit and posterior to the globe [Figure 4d and e]. There were no epithelial components and endothelial lining [Figure 4f].
