Orbital Cholesterol Granuloma: A Case Report

Nanfack CN, Yannick B, Yuanyuan H, Yan L and Lucienne AB

Orbital cholesterol granuloma is a rare entity with few cases describe in the literature. We report the case of a 44 years old male presenting with a proptosis; an inferomedial displacement and motion limitation in upgaze of the left eye. The CT scan reveals an extraconal hypodense mass, frontal bone thinning and erosion infiltration of the zygoma. The management consists on the complete resection of the mass with curettage of the underlying bone cavity. The pathology shows cholesterol clefts; calcifications; and blood products degradation in between mononuclear cells and foamy macrophages and the absence of epithelial element thus confirming the diagnosis of cholesterol granuloma and ruling out dermoid cysts which is an important differential diagnosis.
